National Grid ESO is the electricity system operator for Great Britain.

In order to meet Government set net zero targets, there needs to be an increase in renewable energy sources supplying to the grid. When many renewable energy sources connect – this can cause problems with fundamental network stability. National Grid had studied Virtual Synchronous Machine (VSM) that would contribute to mitigating this risk.

The University of Nottingham were commissioned to create / implement the VSM hardware to validate their simulation model. TTPi built the VSM prototype for this. We were commissioned to create a versatile power controller to allow multiple connections to the power grid for generators, storage etc. 

The main aim was to create a flexible platform to allow renewables to deliver power to the grid in stable manner. 

The majority of grid-connected renewables use algorithms to synchronise with the supply, which limits the amount of energy that can be transferred before the grid becomes unstable. 

National Grid ESO with the University of Nottingham worked on virtual synchronous machine algorithm as a potentially more stable replacement for phase-locked loop systems.
