Progress of Active and Reactive Power Control in Virtual Synchronous Generator
摘要
Abstract
Grid-connected converter is important for distributed generation and microgrid technology in ac system.However,traditional control strategies of grid-connected converter ignores its differences with synchronous generator,which results in excessive rate of change of frequency and other undesired frequency performance.Therefore,virtual synchronous generator is proposed,which aims to imitate synchronous generator to improve frequency dynamics by storages.Considerable researches have investigated virtual synchronous generator control strategies,where active power control and reactive power control are implemented by frequency regulation and voltage regulation respectively.The results suggest its efficiency in relieving frequency problems.This paper discusses control strategies of virtual synchronous generator in voltage control and current control mode,where the active power control corresponding to inertia,droop and damping control and reactive power control are discussed respectively.关键词
