Coordination of Transmission and Distribution data exchanges for renewables integration in the European marketplace through Advanced, Scalable and Secure ICT Systems and Tools (TDX-ASSIST)
An Online Technical Webinar
Wednesday 9th September 2020 | 12.30 to 13:30
This project aims to design and develop novel Information and Communication Technology (ICT) tools and techniques that facilitate scalable and secure information systems and data exchange between Transmission System Operator (TSO) and Distribution System Operator (DSO). The three novel aspects of ICT tools and techniques to be developed in the project are: scalability – ability to deal with new users and increasingly larger volumes of information and data; security – protection against external threats and attacks; and interoperability –information exchange and communications based on existing and emerging international smart grid ICT standards.
First Presentation : Coordination of Transmission and Distribution Data Exchanges for Renewables Integration in the European Marketplace
Within the TDX-ASSIST project, twelve partners from UK, Belgium, France, Germany, Portugal and Slovenia aim to design and develop novel ICT tools and techniques to facilitate scalable and secure information systems for data exchange between TSOs and DSOs. The tools are designed to support active distribution network developments such as the Energy Internet of Things (IoT). TSOs and DSOs around Europe have in-country particularities, but they all face several common challenges. This presentation presents the TDX-ASSIST project with an overview of challenges such as grid observability and controllability; increasing hosting capacity for renewable energies and flexibility services with consumer participation in electricity markets.
Second Presentation : Energy Data Flow Mechanisms in Smart Grid Infrastructure to Enable TSO-DSO Interaction
The increase in decentralized renewable energy sources has created the need for greater coordination between both market actions and grid operations. The transitioning process for the distribution network from passive mode to active mode requires more coordination between the DSOs and TSOs in order to enhance renewables integration through advanced, scalable and secure ICT systems. Smart grid infrastructure is based on unrestricted data flow between the different parts of the grid in order to ensure flexible and reliable services through the different stages of the operation of the network and different time scales. An energy data flow mechanism is proposed in this presentation for the data flow within the smart grid infrastructure to organize the integration process of the renewable energy within the existed energy utilities.

Benefits and Applying to Join
There are many benefits in belonging to and participating within the world of CIGRE. Our members tell us that there are nine major benefits that stand out. For individual professionals, collective members and their wider organisations each benefit is enabled and substantiated by the CIGRE organisation, programme and outcomes it delivers.
1. Be prepared for the future
CIGRE’s unique structure and approach plugs members in to a future focused industry perspective simply not accessible from within a single organisation.
– CIGRE’s knowledge programme is derived from the latest collaborative expertise of thousands of industry professionals.
– CIGRE draws all this together into a strategy firmly focused on addressing the key issues, challenges and trends of the power system of today and tomorrow.
– CIGRE’s Technical Council channels the strategy into a comprehensive, pragmatic, constantly evolving technical programme of work.
– Using state of the art technology and techniques, CIGRE Working Groups systematically develop the workable, on the ground solutions the industry needs to succeed.
2. Learn from real world experiences, lessons and successes
As a collaborative, global community of pragmatic professionals, CIGRE members share best practice, technical expertise and solutions, openly and inclusively discussing and debating their real-world experiences, lessons and successes. By connecting and learning in this way they save time and money and reduce risk.
3. Inform your decisions with diverse perspectives from every corner of the globe
To make optimal power system decisions at home it is essential to take a world view about approaches to the environment, legislation, regulation, technologies and markets. CIGRE’s unique global network of practitioners allows experts to be deliberately selected to ensure a wide geographical representation. Each Working Group usually has experts from each continent, not just Europe or USA.
4. Solve local challenges
At the heart of CIGRE are its 59 National Committees (NCs) spanning over 90 countries. NCs are on the ground, local volunteer driven organisations. They implement CIGRE’s global strategic and technical plans to develop solutions to power system challenges. The solutions are shared across CIGRE’s global network, but ultimately applied locally.
NCs are where you’ll find the most motivated, knowledgeable power system professionals in your local industry. CIGRE gives you access to them and therefore the greatest opportunity to solve your local challenges, whether they be known or emerging.
5. Source the most authoritative reference information
Like the organisation itself, CIGRE publications stand alone as an authoritative technical source of power system knowledge and real-world solutions. The continuously growing body of thousands of CIGRE publications available at e-cigre.org is consistent in its unbiased, rigorous, pragmatic, applied nature. Around the world power industry professionals use CIGRE publications to inform their planning, decision making, product, service and solution development.
6. Get unbiased facts
Another unique aspect about CIGRE is its not for profit, volunteer based, global make up. CIGRE’s fact-based approach is completely unbiased, vendor neutral and open to inclusive, frank discussion and debate about any issues, trends and challenges facing the power industry. There are no hidden agendas at CIGRE.
7. Gain access to world leading experts
The calibre of CIGRE members is very high. Key CIGRE positions are filled by top technical people who have built their expertise over many years of power system experience, often internationally recognised by senior peers as world leaders. This applies at all levels of CIGRE, from Working Group members to Study Committee and Technical Committee chairs.
The Technical Council is peer elected to the level of leadership in their particular domain, thereby forming a group of experienced experts covering all aspects of power delivery.
Access CIGRE experts as your peers in inclusive, collegial situations, learning from them at a nominal cost.
8. Grow your skills
Grow your individual and organisational skills through CIGRE’s unique peer to peer environment and broad training and educational opportunities.
Professional team development is made easy through CIGRE participation, particularly relevant for smaller or isolated organisations, who can’t easily access a peer to peer relationship.
9. Connect with your industry in a technical setting
Grow your individual and organisational network, profile and influence by participating at CIGRE events, on Working Groups and by writing and revising of reports and brochures.
Transmission and distribution utility professionals can connect with product and consulting firms and learn their innovations in a non-commercial environment where the technical side is their focus.

We are excited and honoured to have the President of CIGRE and the Chair of CIGRE UK to share their insights.
Decarbonisation and the current pandemic has created challenges to power industry, but they have also created opportunities. Here in the UK, the carbon intensity of the electricity system has halved over the last five years. We have seen the longest period of coal-free operation in Britain (67 days) and an impressive 83.77% share of zero carbon sources on June 21. These are underpinned by new technologies and more intelligent ways of using energy to tackle the challenges that decarbonisation brings. These are the exciting areas where young engineers and professionals can get involve and contribute to the global effort of decarbonisation.
Wednesday 19th August, 2020 02:00 PM (BST)

Polly Osborne – a passionate champion for a sustainable world
Polly is a passionate individual who is all about making a difference to those around her and driving a better future for society through championing sustainable choices in her personal and professional life. From small things like mandatory adoption of reusable cups through to delivering two industry leading net-zero projects in the energy sector, her influence extends way beyond her current position. She is recognised in her Burns & McDonnell corporate HQ 5,000 miles away as a sustainability leader and has helped establish diversity policies in the UK organisation to achieve 33% of senior leaders as women.
She has made positive choices in her education and in her career, firstly a physics degree and then working at the Carbon Trust before embarking on an engineering degree so she could make practical differences to the way society engineers a lower carbon future. Never accepting second best she achieved a distinction and a special merit prize.
She is a strong influencer for her family, friends and colleagues, holding all to account and leading by example. It’s not always been easy, as she has had to battle institutional and everyday sexism in the workplace, from male bravado to ill-fitting PPE for women on construction sites.
As an assistant electrical engineer Polly would be expected to knuckle down and complete the work she is assigned, working predominantly inside the business with minimal client facing activity. But Polly has done anything but. She has been an outspoken advocate for Burns & McDonnell pursing projects that support net-zero outcomes and developing the engineering solutions that society desperately needs. She asked to be the project manager and through mentoring now leads two projects, E-Port Smart Energy and Zero2050, both radical in their ambition, creating whole energy system roadmaps to decarbonisation. At the professional level she is active in the sector’s women’s network and has recently presented two lectures, one to CIGRE and one to the IET on net-zero solutions.
As Burns & McDonnell UK STEM ambassador Polly leads initiatives to get the whole company engaged and active. From the Big Bang Fair through to school engagement, with a focus on encouraging young women to overcome prejudice about what an engineer looks like and does. Back in the office she supports the recruitment of female engineers through 1-to-1 engagement outside of the formal interview process and advocates for policies in the workplace that support flexibility and diversity.
MVDC Grid Feasibility Within Distribution Networks
an Online Technical Webinar

The evolving distribution networks
Contributor: James Yu
Most responsible governments have committed to a low carbon economy. The UK government has set out a clear ambition to take on the leadership in this international transition. A low carbon electricity network is critical to enable and to realise such a commitment. Unlike a conventional network where centralised generation is to supply all the electricity demands, more and more distribution connected resources (most of them are in the form of renewables) are playing an increasing active role in electricity supply security and reliability. From engineering perspective, the phenomenon can be reflected as the controllable and bi-directional power flow between transmission networks and distribution networks; from the customer perspective, customer can also take on multiple roles simultaneously be a generator or active demand responses party.
The GB Energy System Operator has already made a clear commitment that by 2025, it will have transformed the operation of Great Britain’s electricity system and put in place the innovative systems, products and services to ensure that the network is ready to handle 100% zero carbon. 
The majority of existing electricity networks were built in 1950s and 1960s, therefore a significant investment is required to renovate the network while expanding it at the same time to meet the electricity demand growth. GB networks operators have collectively been set to spend over £26billion between 2015 and 2023 to ensure GB grid can provide adequate available capacity to allow secure energy transfer to the customers, in additional to the £2billion per annum investment planned for transmission sectors and the bespoke Strategic Wide Works such as the Shetland HVDC Link, estimated about £800m. Distribution Network Operator (DNO) serves as the direct interface and takes on active coordinating role between all market participants, facilitating the markets and services in a neutral and non-discriminatory manner.
This can be achieved by extending the current role of DNOs to that of Distribution System Operators (DSOs). An effective DSO model will reduce system balancing costs, whilst enabling the flexible networks necessary to facilitate customer’s use of low carbon technologies. 
Innovation and sustainability have to play the critical role in a post-Pandemic economy. the distribution network is evolved to have more visibility and more controllability than ever before. Decentralisation, Decarbonisation and Digitalisation are the main themes of the distribution network development. Commercial innovations and the engineering advancement alike are required to enable a smarter distribution networks to meet the future requirements of our customers. The technology advancement of power electronics and its commercial availability are the catalyst of this transformation.
The enabling function of power electronics
Power electronics will play a key role in power systems of the future with multiple functionalities. An important area of application is identified in the distribution networks for larger uptake of low carbon technologies. Moreover with the uncertain nature associated with renewable resources (such as solar and wind) and the distributed renewable resources an enhanced co-ordination and management is required. The engineering challenges associated with integrating the unprecedented level of distributed renewable generations can include but not limited to:
- The unpredictable power flow from the embedded generation;
- Imbalance of energy demand between the 3-phase of AC supply;
- Wide voltage angle can prevent the connection between key circuits;
- Voltage control at both transmission and distribution level;
- Power quality
Power electronic device has been conventionally deployed at the renewable sector to fulfil the requirements set out in the Grid Code or Connection Codes, such as Fault Ride Through; Reactive power control (and the voltage control) on the connected busbar. With the help of power electronics solutions, power flow can be controlled in a wide range of conditions, and make it possible to implement widely.
The requirement to maintain a secure, reliable and economical distribution network has seen the increasing activities in both the engineering developments, such as
- The power electronic material (silicon carbide power electronics),
- Hardware design (e.g. new topology of converter; Solid State Transformer);
and the commercial innovation, such as:
- The planning and ownership of Statcom at Grid side
- Integrated function of synchronous condenser and Statcom to provide frequency support
 The customers are potentially paying distributed renewable generators over £1billion forecasted constraint costs within the coming two years (by April, 2022): https://data.nationalgrideso.com/balancing/bsuos-monthly-forecast/r/bsuos_forecast_for_summer_2020_–_including_new_services_–_forecast
Challenges with Power Electronic Devices
In additional to the ongoing engineering and commercial innovation in the power electronic sectors, there are still challenges prevailed over their widespread application in the power systems domain. The challenges associated with proliferation of power electronic devices in the distribution grids can include but not limited to:
- Converter topology suitable for different voltage levels in the distribution grids
- The selection of passive (inductors, capacitors and resistors) and power electronic components, with respect to size and power density.
- Selection of suitable power electronic materials based on application and voltage level (Silicon Carbide, Gallium Nitride etc)
- Reliability of the power electronic and its associated components
- Cost of power electronic devices and associated control systems
- Efficiency and power losses related to power electronic devices.
Existing Project (Pictures and reference)
CIGRE is an established international organisation and taking on the expectations to coordinate and standardise the relevant activities in this sector. Based on the previous efforts from working groups of both C6 (Distribution Systems and Dispersed Generation) and B4 (HVDC and Power Electronics). The newly established collaborative working group: C6.B4.37: Medium Voltage Direct Current has been set up to champion the efforts at international level.
A power electronic-based network upgrade can solve the issues associated with the traditional MV systems such as active control of the active and reactive power, independent reactive power compensation, harmonics and unbalance on the on the AC grids. To this end, a few existing examples are presented here
Example 1: ANGLE DC Project
Angle-DC is a smart and flexible method for reinforcing MV distribution networks, operated by Scottish Power Energy Networks. Angle-DC provides controllable power electronic based flexible connection that facilitates enhanced bi- directional power flow between two sections of the network, Isle of Anglesey and North Wales. The project aims to convert the existing 33kV Alternating Current (AC) assets to DC operation and will trial the first flexible MVDC link in the GB distribution system. Moreover, the project will provide learning to bridge the gap between transmission network and low voltage distribution DC technologies. It is expected that Angle -DC will bring a total saving of £69.2m by 2030 and £396.0m by 2050.
Figure 1 Single line circuit of the Angle-DC link with MVDC topology .
Example 2: LV Engine
LV Engine will trial the application of power electronic based smart transformers (STs) to facilitate the connection of Low Carbon technologies (LCTs). A ST is a power electronic device that provides multiple functionalities over and above standard voltage conversion of conventional transformers. SP Energy networks run the project and aims to demonstrate a low voltage Direct Current (DC) connection for LCTs. It is expected that LV Engine will bring a potential saving of £62m by 2030 and £528m by 2050.
Figure 2 Connection Scheme of SST to LV network 
Example 3: UK Network Equilibrium project
The project aims to install a back-to-back power electronic convertor (AC-DC-AC) which will allow power transfers across two different 33kV networks, called Flexible Power Link (FPL). The FPL will allow controlled transfers of both real and reactive power flows between the two networks. Western Power Distribution (WPD) as part of their “Network Equilibrium” project runs this activity. It is estimated that deploying such flexible power links across the UK could release 1.5 GW of capacity by 2050.
Figure 3 Back-to-back Flexible power link connection between two grids .
Example 4, Indonesia
Coupling of an industrial grid including own generation, highly unbalanced and distorted load (arc furnace) with a public grid. There is a surplus of generated energy in the industrial grid, but both grids cannot directly be interconnected. A back-to-back converter with sufficient rating towards the industrial grid to compensate the unbalance and lower order harmonics interconnects both grids. It reduces the unbalance load on the industrial grid power generators, reduces the harmonics in the industrial grid and enables four-quadrant power transfer between both grids.
Figure 4 Back-to-back Intertie connection between two industrial Grids .
Example 5, China – Wenchang Project
An MVDC system has been provided for CNOOC as part of the Wenchang platform submarine cable repair project. This was provided by the specialist power electronic equipment manufacturing RXPE on a turn-key basis.
The Wengchang project was started in 2010 as a result of customer negotiations and participation with the RXPE business, product development and engineering departments to help address the urgent loss of supply security problem. The MVDC was configured as a symmetrical bipole with a rating of 8 MVA / ±15kV, such that the positive and negative poles are identical and each pole can work independently of the other to provide security of supply to the remote platforms. The projects aims to convert a faulted 35 kV AC line to 3 MW DC line with voltage-source converter (VSC) topology as discussed in .

Example 6 Kylmäkoski, Finland
Pilot implementation of a point-to-point type of LVDC system implemented in co-operation with Elenia Oy (DNO) and ABB Oy Drives. Rectifier is a standard ACS800-11 module where only the bidirectional input power stage is used. The DC-voltage is boosted from normal 570VDC to 750VDC to minimize the DC-current and to maximize the available energy in DC-capacitor bank. The cabinet of the inverter consists of a 150 kVA converter module, an output transformer and an additional DC-capacitor bank as energy storage. The output transformer is a normal dry Dyn distribution transformer with a static shield and 460/400V transformer ratio.

CIGRE UK Women’s Network
25th June 2020 | 13:00 – 17:00 | Online event by Zoom
For special times, we are using the new “norm” to meet together, so the next CIGRE UK Women’s Network led gathering kindly sponsored by BakerHicks is a 4-hour fully online event focusing on clean technologies. As usual, we equally welcome both men and women from the engineering sector.
The zero carbon system operation of the electricity system and its network assets requires a fundamental change in how these are designed to operate, integrating newer technologies right across the system, from large scale offshore wind to domestic scale solar panels and increased demand side participation, by using smart digital systems for real-time management and control.
The first session will focus on clean technologies and how these are and could be evolving in a world post COVID-19. Our main speaker, Danielle Lane, Vattenfall UK Country Manager, will present the challenges and compromises of offshore wind development and how innovation is driving new opportunities. Our panelists, Gianluca Peviani, Dr. Heinz Sittler and Sina Beckmann will then detail some existing and new forms of clean technologies: how non-performing offshore oil platforms can be modified into powerful hydroelectric power plant, how hydrogen can soften the imbalances between electricity production and consumption and how to achieve low-carbon automotive supply chains by enabling, testing and scaling alternative clean technologies.
The second session will be another soft skill workshop with Robert Kahn. “Underlying concepts supporting the leadership model” will focus on the impact equation: Impact = Quality X Acceptance, managing our energy while removing a potential layer of conflict, and entertaining all “offers” while remaining assertive. This builds on the LeaderLike model introduced during our March event which will be summarized for new participants.
The third session will feature online networking with opportunities for participants to split into different virtual breakout rooms, each room being led by a panelist who will conduct a deep-dive into a clean technology topic addressing additional questions interactively.
The event is organised by the CIGRE UK Women’s Network for which a modest fee to register with payment by credit card only will be required (7-day refund before the event policy applies). Participation is limited due to the networking opportunity offered within each breakout rooms, so please book early!

CIGRE NGN Joint Wind Energy Webinar
Wednesday 17th June 2020
14:00 – 16:00 (BST)
In 2019, 60.4 GW of wind energy capacity was installed globally, a 19% increase from installations in 2018 and the second-best year for wind historically. Total capacity for wind energy globally is now over 651 GW. So how can we exploit the full potential of wind energy?
The speakers/topics are: –
- Professor Vladimir Terzija, “Smart Frequency Control in Power Systems with a High Penetration of Nonsynchronous Generation”.
- Dr Xianxian Zhao, “Fast Frequency Support from Wind Turbine Systems by Arresting Frequency Nadir Close to Settling Frequency”
- Dr Peter Wall, “Identifying scarcities on the All Island system in 2030 – perspectives from EU-SysFlex”
- Tolulope Mayomi, “The opportunities of dynamic line rating for overcoming curtailment challenges”
In light of the current global situation, the CIGRE UK and CIGRE Ireland Next Generation Network (NGN) committees have come together to create their first joint, online webinar on the topic of Wind Energy. Please note that the webinar is free and open to all members, however, registration from NGN members will be considered first if the numbers exceed our hosting capacity.
The event will be hosted via an Online Conference Platform. Please sign up to the Eventbrite page and you will receive the link and detailed agenda by email.
The proliferation of power electronic devices is resulting in new challenges within the power quality area. One topic that has seen an increased level of attention within the power quality area is harmonic distortions.
Traditionally, harmonics have been dealt with at the planning stage and mainly at transmission level in detail. That trend continues today with an increased emphasis on all connections that include power electronic converters. However, it is not simply the sheer amount of increased connections that is driving this enhanced level of attention. The equipment being introduced as well as the system itself, is changing. In the past, harmonic injections were confined to a few characteristic harmonics, but this is no longer the case. With renewable generation technologies utilising inverter-based grid connection characteristics, it is quite common to see harmonic injections at a wider harmonic spectrum. The system is also changing with the addition of an increased share of cable circuits bringing the system resonant frequencies to the lower end of the frequency spectrum.
Standards, technical recommendation and/or industry guidance documents that are being relied upon are becoming outdated and require updating to accommodate this increased contribution. Furthermore, the need to plan the system, such that the contribution from many sources is minimized, is increasing – not just at transmission level, but also in distribution systems due to the increased integration of distributed resources.
The subject matter of the talk is going to be development/state of the art in harmonics with four subject matter experts reflecting from their experience in working with harmonics.
To register for this event click here
Presentation and Discussion Topics:
- Introductory talk on harmonics to provide a basic overview of the subject matter, historical treatment of various types of connections, types of harmonic studies and/or calculations, why the industry should be concerned about harmonics, what is being done and where, do we see any international trends, is the industry late in starting to deal with harmonic distortions, what is being done at standardisation level? The presentation and discussion will be led by PSC’s Dr Zia Emin.
- The second talk will be on the application of the international standard (or rather the technical report adopted as standard by many countries) IEC 61000-3-6, and the difficulties faced in its application in complying with harmonic distortions by the TSOs that adopted the approach. This talk will concentrate on specific experiences of the Irish TSO, the difficulties of applying a methodology that provides relatively small emission limits, what can be done to alleviate these issues and how the standardization should take these into account in future revisions. The presentation and discussion will be led by a representative from EirGrid (Marta Val Escudero).
- The third talk will concentrate on how the UK industry has taken the case of increased penetration of renewables and its impact on the system harmonics and how it went about revising the applicable industry recommendation to cover new areas and change the approach of allocated limits. The audience will be able to understand what is changing with the new standardization, what it brings and how that may impact the various connectees. This talk and discussion will be led by a representative of a UK transmission owner, who have been dealing with such system modelling issues and have first-hand understanding of the impact the changes will bring and what is going to change. (Dr Forooz Ghassemi)
- The last talk takes the matter into distribution territory where quite a lot of changes are being observed. The talk will initially give an overview of the harmonic distortions from a distribution system level, before moving into active filtering. Development, both now and in the past, has been based on passive shunt mitigation measures when issues are encountered. However, with an increased number of inverter-based technologies, especially at distribution level, the possibility of changing the source of harmonic injecting devices into an opportunity where they can be utilized as active filters is gaining momentum. This talk will explore that angle and give the full background on an ongoing project where this is being tackled. The talk will be led by a distribution system engineer from Western Power Distribution, who is working actively on the harmonic mitigation via active filters project. (Chris Harrap).
The talks will be followed by a networking session with light buffet and drinks.
