Helping the UK Power Grid Spin Back its System Inertia
Inertia acts rather like a car''s shock absorbers that smooths the shock over bumps in the road. Inertia provides a response that is temporary and is typically available for only a few seconds. That allows the power grid to ride though short duration faults. This keeps system frequency within controlled limits of around 50 Hz.
