Agenda

  • 5min: Introduction to Italy NGN
  • 5min: Introduction to UK NGN
  • 20min: Dr. Luigi Calcara (University of Roma “La Sapienza”- Italy) ‘Heatwaves effects on MV electrical grid’
  • 20min: Dr. Eduardo Alejandro Martínez Ceseña (University of Manchester – UK) ‘Techno-economic modeling and assessment of forward resilience measures’
  • 10min: Round table discussion

 

Abstracts

Heatwaves effects on MV electrical grid – In the last years, the frequency and the intensity of adverse meteorological conditions are on the rise and climate changes have the potential to affect negatively the electrical systems in many different ways. Local or extended electrical outages have been and are caused by extremely severe negative meteorological events of different nature, like strong winds, wet snow, heavy rain, and heatwaves. Of course, such interruptions of electrical systems affect also critical infrastructures with a negative impact on all human and industrial activities. To face this reality, the Italian Regulatory Authority for Energy, Networks and the Environment (ARERA), established new more stringent rules to maintain high standards of power quality services also through a more resilient electrical system. For this reason, there have been established very ambitious benchmark values for the key performance indicators, normally used to evaluate the quality of electric service. With the aim to increase the resilience of the distribution electrical networks, the DSOs are studying and developing new grid operations with improved assets adopting also advanced electrical technologies. In particular, the medium voltage joints are currently one of the components which require more attention: in fact, they make the system more vulnerable due to possible imperfections introduced during the construction phase both for unperfect manpower and for the complexity of the operations.

Techno-economic modeling and assessment of forward resilience measures – The importance of developing resilience energy systems is attracting research interest due to the recent climate change-driven extreme weather events experienced in different parts of the world. For example, in the UK, Ofgem (the network regulator) has highlighted the importance of considering resilience when developing the power system. However, as resilience is still an emerging topic, there are no standardised metrics and methodologies to quantify resilience and include it in operation and planning practices. This presentation provides an overview of the latest research from The University of Manchester which aims to address these research gaps. To be more specific, the key differences between classical reliability and resilience studies will be presented. The adequacy of different metrics and approaches used to quantify resilience will also be discussed. Proposed approaches to simulate the impacts of extreme events such as wind storms and floods will then be explored in the context of smart systems in urban areas and off-grid systems in isolated locations. The effectiveness of different resilience measures, such as asset hardening and the use of system flexibility, will be discussed in different contexts.

CIGRE UK NGN Young Members Showcase – The Winners

By | Blog, NGN Events | No Comments

The NGN Committee of CIGRE UK hosted an online presentation competition on 5th February 2021 to select the best UK young professionals to present at the upcoming CIGRE Centennial Paris Session in August 2021. The Paris Session includes a Young Member (YM) showcase for young professionals to present their contributions to CIGRE’s domains of work before an audience of leading experts from all around the world.

The NGN steering committee assessed abstracts and invited seven candidates to present their work at the presentation competition. Each presentation was judged by a panel of four senior CIGRE UK members, including Dr. Diptargha Chakravorty, Dr. Qiteng Hong, John Wright, and Dr. Konstantinos Kopsidas. Winners of the competition were nominated to attend the 2021 Centennial Paris Session and receive free tickets and a bursary towards travel if approved by the international CIGRE NGN committee.

The CIGRE UK NGN committee is delighted to announce the four winning candidates are:

 

Harry Evans1

Harry Evans, graduate electrical engineer at GHD, for their presentation entitled “Boston Spa Energy Efficiency Trial.”

Bio: Harry is a consultant electrical engineer working within GHD’s Energy team. During his time at the company, he has worked on a range of projects covering: SMART grid design of distribution networks; power systems modelling of generation connections; and he has co-authored a review into emerging transmission technologies. Harry has gained experience outside of his role at GHD in the development of fault level calculation code for application in offshore wind farm design software, and a continuing role as a contributing member to CIGRE WG B4.89.

Synopsis:What if a relatively small change at a substation level could reduce the regions carbon emissions and shrink customer bills? NPGs voltage optimisation trial in the town of Boston Spa is hoping to achieve just that. This presentation covers the initial stages of the project, which investigated static optimisation of substation voltages, and how customer smart meter data can be used to monitor and control the network more efficiently.

 

Rui Jing1Dr. Rui Jing, research associate at Cardiff University, for their presentation entitled “Planning extreme weather resilient urban energy systems.”

Bio:Dr. Rui Jing is a Research Associate in Cardiff University working with Prof. Nick Jenkins and Prof. Jianzhong Wu. His research focuses on multi-energy system modelling, urban energy transition, climate resilience energy systems, and energy-related nexus research. He got a Ph.D. from Xiamen University, China in 2019. He also has visiting experience in Imperial College London (2018-2019), research experience in the Chinese Academy of Science (2019-2020), and industry experience in energy auditing consultancy (2013-2015). So far, he has more than 20 journal publications, and the H-index is 11. He is also active in academic activities, e.g. acting as session chair for international conferences and serving as reviewers for more than 10 journals. He was recognized for several best paper awards and several outstanding reviewer awards.

Synopsis:Global climate change leads to more frequent and intense extreme weather events, such as typhoons, heatwaves, and rainstorms, which has posed serious risks for urban energy systems. Without preparation for such risks, the city administrators can only hope the next extreme weather event would not trigger a sudden blackout. Therefore, we propose an original planning model to design a ‘climate-resilient’ urban energy system and bridge the gap of addressing extreme weathers during energy system planning. The case study reveals that by investing an acceptable extra 3-5% could help design  a  ‘climate-resilient’ urban energy system.

 

Caleb Waler1Caleb Walker, graduate engineer at Scottish Power, for their presentation entitled “Accurate Prediction of Transformer Residual Life.”

Bio: Having graduated from Glasgow Caledonian University with a First BEng in Electrical Power Engineering in 2020, I am currently employed as a graduate engineer with SP Energy Networks.

Synopsis: The ageing process of power transformers is a complex mechanism, which means condition and health assessment of these critical assets is a challenging task. While transformers are in-service, obtaining insulating paper samples from the windings for direct analysis cannot easily be achieved, meaning the only practical way of assessing the state of degradation of the paper insulation is through prediction models. A new prediction method is currently being developed using Post-Mortem reports to give a more accurate estimate of the remaining useful life of transformers compared to existing methods, thus avoiding costly interventions or replacement of these high value assets.

 

Shuren WangDr. Shuren Wang, research associate at the University of Strathclyde, for their presentation entitled “A T-Type Modular Multilevel Converter (T-MMC) to Improve System Security.”

Bio: Shuren Wang is a researcher of the Electronic & Electrical Engineering Department at University of Strathclyde. He received the B.Sc. (Hons.) and M.Sc. (Distinguished) degrees from Yangzhou University, China, and the Ph.D. degree from University of Strathclyde, U.K.. His current research interests include power conversion, power electronics, MVDC, HVDC, and energy storage systems.

Synopsis: Power electronic converters are enabling massive integration of renewable energy sources. Meanwhile, system security and fault resiliency are increasingly concerned. A T-Type Modular Multilevel Converter (T-MMC) using state-of-the-art power electronic technology will be presented for bulk ac-dc power conversion applications. The salient features of the proposed T-MMC include: (1) resiliency against ac and dc faults; (2) effective ac grid support; (3) high operation efficiency; (4) flexible and efficient energy storage integration; (5) uninterruptable power flow during faults with the integrated energy storage.

 

Keep an eye out as we are due to hear back about the success of the nominated candidates in the coming months.

Examples of these efforts are increasing the renewable generation share of the total generation and increasing the efficiency of the power system and its equipment. But both of those solutions always faced a limitation like hosting capacity (HC) which represents the limit at which the current power system can accept renewable generation. Also the aging power systems equipment always stood as a hindrance in front of a sustainable grid. That’s why climate change and other technical and economic issues were always ahead of these renovation efforts. In this presentation we will discuss the role of the 4thindustrial revolution and its related technologies like the Internet of Things (IoT), Artificial Intelligence (AI) and Big Data (BD) in accelerating the renovation of the current legacy grid into the smart energy grids of the future.

Topics:

Lightning Phenomena in the Alpine Region of Austria – Lukas Schwalt

In the first part of this presentation, an introduction about thunderstorm formation and lightning physics will be given and secondly the key findings of Dr. Schwalt’s PhD thesis “Lightning Phenomena in the Alpine Region of Austria” will be presented. The motivation for the PhD thesis was to gather lightning ground truth data for Austria out of on-site measurements, because this area shows high lightning activity. For this purpose, real processes of cloud-to-ground flashes were recorded with a high-speed video camera and an electric field measurement system. Analyses of this exclusive data set provide insights about lightning characteristics in general and for the alpine region in particular.

 

Effect of Network Parameters on the Transient Over-Voltage Phenomenon During System Restoration – Diptargha Chakravorty

System restoration is currently a transmission-led approach of starting large conventional generators with self-start capability and energising a skeleton network. Increasingly, transmission connected fossil-fuelled generators are decommissioned around the world to meet the emissions targets. This makes it imperative to explore the possibility of using distribution connected DERs to support the whole system restoration.  However, energisation of network elements such as circuits and transformers pose significant challenges such as switching transients, Temporary Over Voltage (TOV) etc which can reduce the available options to restore a network and lead to a higher number of circuit breaker switching to avoid damaging equipment. This presentation will discuss the impact of different network parameters such as the strength of the system, saturation characteristic of transformers etc on the TOV and ways to manage it during restoration.

 

Speakers:

Lukas Schwalt is a CIGRE NGN AT member and he is a Post-Doc researcher at Graz University of Technology, Institute of High Voltage Engineering and Systems Performance. After completing his master in Electrical Engineering at Vienna University of Technology, he successfully defended his PhD thesis “Lightning Phenomena in the Alpine Region of Austria” at Graz University of Technology in 2019.

webinar_challenges_opportunities_02

Prof Zhang then highlighted the Energy research at Birmingham including smart grids, HVDC and FACTS, renewable energy control, energy storage, energy materials, transport, and energy policies. Prof Zhang mentioned that Birmingham is a great city very much related to the 1st industrial energy revolution, i.e., triggered by the development of commercial steam engines by James Watt in Birmingham in 1776. In recent years, Birmingham was named as the National Energy ‘Capital’. This would certainly encourage exciting low carbon energy technology developments as well as international collaborations.  Finally, he pointed out that the energy challenges could not be tackled by a single country alone. International collaborations become essential for successfully implementing the Paris agreement on Climate Change. CIGRE is certainly an excellent platform to facilitate international collaborations, propose innovative smart grid solutions and support individual career developments.

webinar_challenges_opportunities_03

Rob Stephen first highlighted the conflicting nature between ‘high reliability and security of supply’, ‘most economical solution’ and ‘best environmental protection’ aspects of power system. Rob then introduced the CIGRE’s technical activities (16 Study Committees, around 230 Working Groups with over 3800 experts from all over the world) and the structure of CIGRE. He then moved on to share his view on the challenges and opportunities from an extensive range of power system aspects, including active distribution networks, massive exchange of information, integration of HVDC/power electronics, significant installation of storage, new systems operations /controls, new concepts for protection, new concepts in planning, new tools for technical performance, increased use of existing infrastructure and new T&D developments and stakeholder awareness. Finally he highlighted the Power to Gas technology as the ‘Next Disruptor’, the potential of ‘e-Hydrogen Future Network’ and the grand vision of North Sea Wind Power Hub.  During Q&A session, he explained how CIGRE Steering Committee interacts with Technical Council and provided advice to young professionals on how to get involved in CIGRE and engage with the wider power community.

webinar_challenges_opportunities_04

Adam Middleton started off his presentation on his understanding of global megatrends – Decarbonization, Decentralization, Digitalization, Demand Growth and Diversity of Solutions. Adam highlighted the importance of considering effectiveness, sustainability of solutions, societal acceptability, and the need to act now to tackle the challenge. He also pointed out that the key to energy transition is ‘about how we get there and the only way we get there is to start with what we have’. He moved on to share his view of the impact of COVID-19 by adding new volatility, uncertainty, complexity and ambiguity to energy transition. He mentioned the important role of national governments under COVID-19 in supporting the recovery and transition of energy industry to move into a more sustainable future – ‘do not waste a good crisis’, said Adam. Finally, he emphasised the important role of considering sector coupling, the need of green hydrogen (from electrons to molecules) and the technical and economic challenges associated with it. During Q&A, Adam pointed out the importance of considering whole life cycle process when assessing the ‘Green level’ of a specific solution.

On Wednesday 17th, June 2020, 14:00 – 16:00 (BST), the CIGRE UK and CIGRE Ireland NGN came together to have their first joint, online webinar on wind energy.

The event was based on the background of the growing research and application of wind energy in the past decades of years. 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?

Four guest speakers were invited to share their perspective and experience on wind energy, including the latest research and development, pilot and commercial projects. The detailed information of the guest names and corresponding topics were:

  • Professor Vladimir Terzija, “Smart Frequency Control in Power Systems with a High Penetration of Nonsynchronous Generation”
  • 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”
  • Dr Xianxian Zhao, “Fast Frequency Support from Wind Turbine Systems by Arresting Frequency Nadir Close to Settling Frequency”

The event was successfully organised with more than 100 participants. Apart from the presentations, interactive polls and Q&A sessions were also taken place. With the rapid development of wind energy technology, the wind generation is anticipated to be one of the most significant contributors to meet the UK’s ambitious net-zero emission target.

CIGRE NGN Visit to St John’s Wood Substation, London, England

By | NGN Events | No Comments

On Tuesday 26th November 2019, members of the CIGRE UK NGN visited the St John’s Wood substation in London, one of most compact and complex substations operated by National Grid. This substation is the grid supply point (GSP) for both Westminster and Kensington & Chelsea boroughs. St John’s Wood substation hosts what is known as The London Connection, a 20km tunnel for a 400kV XLPE cable connection between Elstree and St John’s substation. This connection supports the supply for North West London and the City.

Before starting the visit around the substation, Julio Perez gave an overview of CIGRE UK and the activities organised by the NGN. Following this, James Watson from National Grid delivered a technical presentation on the importance of St John’s substation in the high-voltage supply for London, its configuration, as well as the type of equipment found at the substation.
StJohnsWoodSubstationt_01
After a safety briefing by James, the first stop was The London Connection underground tunnels, which houses the 400kV XLPE cables used for the connection to another major substation, Elstree. The London Connection is part of a series of underground tunnels designed to meet the increasing electricity demand from London whilst minimising road disruption.

StJohnsWoodSubstationt_02StJohnsWoodSubstationt_03

Then we visited one of the buildings containing some of the gas-insulated switchgear, to reconfigure the supply points when required. James explained to us how the gas-insulated mechanism operated to interrupt an arc when opening circuit breakers and also what are the main procedures for managing faults. At the end of the visit, we had the chance to visit one of the main super-grid transformers which serve to step-down the voltage from the transmission level, from 400kV to 132kV.

CIGRE NGN-IEEE Student Branch Joint Event, University of Manchester, UK

By | NGN Events | No Comments

On Wednesday 17th July 2019, the IEEE Student Branch UoM and the CIGRE UK NGN co-hosted an event at The University of Manchester. The event attracted 24 attendees, mostly new MSc and first-year PhD students.

The event had two primary aims: to increase awareness of IEEE Student Branches / Chapters and CIGRE NGN; and bring attention to the types of resources useful to young researchers produced by the IEEE and CIGRE.

These aims were met in the event through three talks. The first was delivered by James Hill, the CIGRE-UK NGN Institutions Collaborations Lead and Past-Chair of the IEEE PES Student Branch Chapter at UoM. His talk introduced the two institutions of IEEE and CIGRE, explained which publications are available from them, and how to be involved and get the most from the Student / NGN societies.

After this introduction, Prof. Paul Jarman explained how research can actively influence the direction that standards take, and conversely, how standards can help to influence and direct our research. Prof. Jarman drew on his vast experience from involvement with standards related to transformers to explain the process required for their establishment and revision.

Finally, Dr. Mathaios Panteli presented on his experience as a young researcher involved in a CIGRE working group during his PhD. He highlighted how beneficial this was to his career and how ideas he got from conversing with the senior personnel he was exposed to in this environment helped to add significant value to his final thesis.

CIGRE NGN Visit to Boskalis’ Cable Barge, Vlissingen, Netherlands 

By | NGN Events | No Comments

On Thursday 3rd May 2018 a group of 14 Cigre-UK NGN members travelled to the Netherlands for a unique opportunity to visit Boskalis’ Giant 7 cable barge.

The day started with technical presentations at Boskalis’ offices in Vlissingen where attendees were able to learn about subsea cable installation and repairs, and the interesting challenges faced. This was followed by an introduction to some of Boskalis’ past and present projects as well as a visit to their storage site at Vlissingen port where there was the opportunity to see the newly-built BS-III trenching tool .Cable-ship-2-300x225

In the afternoon, the group travelled to Rotterdam where the Giant 7 barge  was docked. The barge was being made ready for service and this allowed a great opportunity to explore and to understand the amount of work that goes in behind the scenes before the cable and trenching tool can be brought on board.

We would like to thank all of our attendees for their enthusiasm and questions throughout the day, and of course the team at Boskalis for their hospitality and especially for letting us stay on board for an extra couple of hours due to the interest and number of questions! Special mention goes to Hans Veth and Jack Wattel at Boskalis and to Tony Zymelka from ESCA (European Subsea Cables Association)/BBP Cables for their support in the organisation of this unique and fantastic event.

Following this success, we hope to add another cable ship visit to our 2020 events calendar so watch out for information on this soon!cable-ship-1-300x225
