A CIGRE UK NGN and Study Committee B4 Collaboration.

Grid Forming technology is one of the potential solutions that can support zero carbon operation of GB’s electricity network. CIGRE UK NGN, in collaboration with experts from Study Committee B4, has organised this technical webinar to discuss the latest developments in Grid Forming technology in the UK. Dechao Kong, CIGRE UK Regular Member for B4 (DC Systems & Power Electronics) chaired this webinar, introduce the topic and provide an overview of the work of Study Committee B4.


13:00 – 13:10 Welcome & Overview – Dechao Kong | UK Regular Member B4

13:10 – 13:15 Introduction to the NGN – Siva Kaviya

13:15 – 13:50 Presentation/Q&A – Ben Marshall

Title: Verifying Grid forming technology performance- National HVDC centres experiences of Grid Forming.

Abstract- Grid forming converters come in a number of forms and have a number of applications and capabilities, many existing, some new, some evolving. However, what is critical is that the definitions between them are understood and that tests and modelling demonstrate and verify acceptable performance is provided. The National HVDC centre will describe its experience in supporting demonstration and testing across these topics.

13:50 – 14:25 Presentation/Q&A – Agusti Alvarez

Title: Demystifying grid forming converters: challenges and opportunities of a new converter control technology.

Abstract: Grid forming converters are seen as a central piece on the development of the future (and present) converter dominated networks, but are grid forming converters a silver bullet? This presentation will discuss the main implementations, advantages and challenges and review some of the recent projects.

Dechao Kong is the elected UK Regular Member of CIGRE B4 Study Committee since August 2020. He is currently a Power System Engineer and the Subject-Matter Expert in DC Systems and Power Electronics in National Grid ESO, UK. Dechao has been getting heavily involved in the UK’s academia and industry since 2008, contributing his such subject-matter expertise in technical strategy & policy development, new technology & innovation, engineering and asset management in the areas of DC Systems and Power Electronics. Dechao obtained his Ph.D. degree in Electrical Engineering from the University of Birmingham, UK. He is a Chartered Engineer and an IET member in the UK. He is also an active member with multiple roles in several CIGRE SC B4 & B5 Working Groups.




Ben Marshall oversees the team of Simulation Engineers undertaking detailed HVDC simulation studies in real-time using vendor-supplied replica hardware, to understand multi-infeed, multi-terminal and multi-vendor HVDC operation and interactions, for real schemes in GB; interpreting the results to gain insights to improve the design and operation of HVDC schemes.  Ben previously has had a 23 year long and varied career within National Grid with a broad range of experience, particularly with respect to the analysis of the operation and design of the AC and DC transmission systems. He has experience in both offline and realtime EMT simulation and in modelling of convertors across battery, solar wind and HVDC systems, He has developed deep technical skills relating to dynamic stability of power systems and the performance specification of HVDC convertors. Within the ESO, Ben advised on the specification, validation and modelling of new HVDC connections, supporting the compliance connection planning and requirements and provided technical leadership on AC and DC control systems, System Operability, Smart Grids and power system simulation; leading complex power system studies.



Dr Agustí Egea-Àlvarez has been a Senior Lecturer at the electronic & electrical engineering department of the University of Strathclyde since 2018. He obtained his BSc, MSc and PhD from the Technical University of Catalonia in Barcelona in 2008, 2010 and 2014 respectively.  In 2015 he was a Marie Curie fellow in the China Electric Power Research Institute (CEPRI). In 2016 he joined Siemens Gamesa as converter control engineer working on grid forming controllers and alternative HVDC schemes for offshore wind farms until 2018. His research interest are: control of grid-connected converters control, hybrid AC/DC networks modelling and control and advanced converter topologies for grid-connected applications.   He is a member of IEEE, IET and has been involved in several CIGRE and ENTSO-E working groups.
