Power Potential trials: a new ESO reactive power service from DERs in DNO networks 
Wednesday 4th March 2020 | 12.30 to 13.30


Power Potential is a TSO/DSO innovation project between National Grid ESO (the Electricity System Operator in Great Britain) and UK Power Networks (the distribution network company in the south-east boundary of Great Britain). The project aims to enable DERs connected to the distribution grid, to provide coordinated transmission services to the ESO, whilst maintaining distribution network security. The focus of the project is on the delivery of a dispatch control platform (DERMS, distributed energy resources management system) and a commercial market framework to validate and value the dynamic voltage control that can be exercised through these DERs.

This is the first trial of its kind to obtain reactive power services from DERs, to further utilise their potential under a new regional reactive power market. It involves a great deal of collaboration and coordination between the transmission and distribution companies, following a true whole-system approach.

This webinar presents the Power Potential trials preparation, to cover both technical and commercial aspects of the project. An overview of the Power Potential solution is presented here, and the design of the project trials is explained in detail. This includes the description of the instructions to dispatch DER in real-time following the virtual power plant concept and the commercial arrangements for the market trials. DER commissioning activities to ensure DER preparation for trials are also covered, as well as testing and business readiness aspects.

Richard is currently a Innovation Workstream Lead at UK Power Networks, where he is part of the team delivering the Trials workstream for Power Potential. With a career spanning more than 37 years in the Energy Sector, Richard has developed a wide industry knowledge from both the electricity generation and transmission sides of the business. For much of this time he has worked for National Grid, developing operational and commercial experience of the electricity networks in England and Wales. In more recent years, Richard has been a Lead Project Manager for National Grid, delivering a number of high value, complex substation projects in the South-East.






Inma Martinez Sanz, Power Systems Engineer, National Grid ESO

Inma is a Power System Engineer at National Grid ESO currently working for the Power Potential innovation project. She is leading and supporting the project technical delivery in terms of developing a novel control platform to provide reactive power services from distributed energy resources. Before joining National Grid, she was a Research Associate at Imperial College London where she obtained the Ph.D. degree in Electrical Engineering in 2015. Inma has extensive experience in the electricity sector, covering academic and industry research. In particular, her work in these years has mainly focused in the areas of power system dynamics and control, HVDC transmission, transmission/distribution interaction and grid integration of renewables.





Biljana Stojkovska, Power Potential Project Lead, National Grid ESO

National Grid Innovation Manager Dr. Biljana Stojkovska is an esteemed figure in the energy revolution with one of the most transformational projects that the energy industry has seen. The project is called Power Potential and Dr. Stojkovska is leading a team that will be pioneering a whole system approach to connect additional renewable energy and storage technology in a new regional power market trial.  This trial is expected to improve interaction between National Grid’s System Operator (SO), regional electricity distributors and renewable energy generators connected to the distribution system to create a cost effective new revenue stream and give greater robustness to the power system. This project is looking at how using previously unexploited power can benefit the energy industry and in turn all electricity consumers.  Addressing parity in the workplace, Dr Stojkovska is also a key member of the highly respected international council of large electric systems, CIGRE, and a passionate Chair of its Women’s Network advocating greater diversity in the engineering and energy sector. Dr Stojkovska is also a Chartered Engineer (CEng), Fellow of the IET (FEIT) and a EUR ENG.
