Implementing Virtual Synchronous Generators for Renewable Integration
, 2022 In older centralized power systems, power is often generated by massive synchronous generators (SGs), with the grid frequency defined by the prime mover's rotational frequency. The rotor inertia attribute prevents the frequency from shifting and keeps the system stable if the load changes quickly.
