National Grid VSM/GCF Innovation Projects and Grid Code Proposal

The presentation will discuss National Grids innovation projects relating to Virtual Synchronous Machines / Grid Forming Convertors (VSM/GFC), which have contributed to the GC0100 Grid Code proposal of 2018 and more recent proposal of October 2019. The introduction will cover the history of the projects. It will then focus on the more recent work undertaken by National Grid and the Universities of Nottingham and Strathclyde and conclude with an update on the VSM/GFC Grid Code Workshop and Workgroup proposals.

The University of Nottingham project, “VSM Demonstrator” looked at various aspects of one particular implementation of VSM, particularly in relation to the general algorithm, the power and current limiter and the impact on harmonic performance.

The University of Strathclyde project, “Hybrid Grid Forming Convertors” uses a similar algorithm but applied to the STATCOM whilst leaving the generation largely untouched. This arrangement was thought to be particularly beneficial in offshore and retrofit applications. The project also compared the performance synchronous compensators of similar rating.

The VSM/GFC Grid Code Workshop is now concluding with plan in 2020 to convene a Work Group which will have the power to implement the Grid Code change.
