C4 Liaison Meeting Agenda



C4 Study Committee Mission, Technology & Scope

Screen Shot 2021-01-07 at 11.20.13


Within its technical field of activity, Study Committee C4 deals with methods and tools for analysis related to power systems, with particular reference to dynamic and transient conditions and the interaction between the power system and its apparatus/subsystems (including external causes of stress and other installations). Specific issues related to the design and manufacturing of components and apparatus are not in the scopes of SC C4, as well as those specifically related to planning, operation and control, apart from those cases in which a component, apparatus, or subsystem behaviour depends on, or significantly interacts with, the performance of the nearby power system.



Within this framework, specific areas of attention include:

  • Power Quality Performance: Continuity of end-to-end electric power supply and voltage waveform quality (magnitude, frequency, symmetry). Analysis covers emission assessments from disturbing installations, measurement and simulation methods, identification of quality indices, monitoring techniques, immunity of sensitive installations, and mitigation techniques taking into account a co-ordinated approach across all voltage levels.
  • Electromagnetic Compatibility (EMC): High-frequency disturbances on the end-to-end electricity supply and all disturbances (HF or LF) reaching equipment other than through the electricity supply. Studies include measurement and simulation methods. Health effects related to low frequency EMF are however excluded.
  • Power System Dynamics: Development of advanced tools and new analytical techniques for assessment of power system dynamic/transient performance, security, design of controls and modelling of existing and new equipment, real-time stability evaluation and control.
  • Lightning: Analysis of lightning characteristics and interactions of lightning with electric power systems and equipment, including protection in MV and LV networks against lightning, and their standardisation.
  • Insulation Co-ordination: Methods and tools for insulation co-ordination and electro-magnetic transient analysis in electric power systems and equipment, contributing to optimisation of their cost and reliability.

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.

  3. Analyse network security under N-1 line contingency for all scenarios under the whole planning period.


Caleb Walker – Accurate Prediction of Transformer Residual Life

Caleb Waler1Bio: 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.


Harry Evans – Boston Spa Energy Efficiency Trial (BEET)

Harry Evans1Bio: 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.

Mohamed Ahmed Numair – IoT-based Demand Side Management of a Renewable Energy Powered Smart Microgrid

Mohamed Ahmed Numair1Bio: Mohamed Numair received his B.Sc. in Electrical Power Engineering from Tanta University, Tanta, Egypt, in 2019. He is currently pursuing his M.Sc. thesis in the demand side management of smart grids using the Internet of Things (IoT). He has just completed some modules from MSc Smart Grids and Energy Systems, University of Bradford, UK, as an Erasmus exchange student. He is also currently working as a research assistant at the high voltage and superconductivity laboratory, Tanta University. Where he is building an Internet of Things Innovation laboratory. His research interests include Smart Grids, Renewable Energy, Internet of Things (IoT) and Energy Management.

Synopsis: For the past few decades we have noticed global efforts into a green and sustainable energy system. 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.


Shuren Wang – A T-Type Modilar Multilevel Converter (T-MMC) to Improve System Security

Shuren WangBio: 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.


Jiabin Fan – Three-phase OPF Based Demand Response for Managing Unbalanced Voltage under High Renewable Energy Scenarios

Jiabin FanBio: Jiabin Fan received first class undergraduate degree from University of Strathclyde in electricity and electrical engineering department in 2018. He is currently working toward the PhD degree under the supervision with Dr. Ivana Kockar and he is the University John Anderson Research Award Studentship recipient. His research interests include optimal operation of distribution system, modelling DERs and local flexibility market.


Synopsis: With the increasing penetration level of renewable energy sources (RES) in distribution systems, there is an increased risk for occurrence of a three-phase voltage unbalance which could exceed security standard. This presentation introduces a method which seek to utilize the active domestic load response to provide flexibility services for distribution system operators (DSOs) which can also help balance the three-phase voltage. The analyses assume that the flexibility providers can receive economic compensation according to their contribution to their provision of flexibility services

Optimising subsea cable sizing: through improved modelling

An Online Technical Webinar

Wednesday 10th February 2021 | 12.30 to 13:30


As offshore wind farms have grown in number, in size and in distance from the shore, so too has the need for subsea high voltage power cables. With cabling now representing a significant part of the total cost of constructing wind farm projects, it is essential to optimise the design of the cable system such that it is best sized to cope with the required loads. Multiple separate activities are ongoing within Cigre B1 which will contribute to this optimisation process in the future. This webinar will introduce some of the challenges being tackled within Cigre B1, exploring the way in which the cable sizing models used in the design phase can be refined to ensure that the correct cable is selected for each project.

Bio: Phil Moore trained with GEC ALSTOM, Stafford and worked as a Relay Design Engineer before moving into academia. Over a period of 20 years he worked at several Universities, specialising in Electrical Power Engineering. In 2007, whilst Professor of Electrical Plant and Diagnostics at Strathclyde University, he co-founded Elimpus which is a condition monitoring solutions provider to the electricity supply industry. He has been the full-time Technical Director of Elimpus since 2009.

Why is innovation collaboration important: Relatively few innovations come about by groups working in isolation, rather, successful innovations require team work from the entire supply chain from manufacturers through to solution providers through to the end user.
