Voltage Control Strategies for Microgrid With Multiple Inverters
摘要
Abstract
For dealing with inaccurate distribution of reactive power caused by sever coupling between active and reactive component and voltage droop by adding virtual reactance to inverter during islanded operation of microgrid, a new online estimation of reference voltage for the first voltage controller of virtual synchronous generator （VSG） was proposed. An anticipant electromotive force （EMF） was estimated in advance according to the dispatched active and reactive power. This method would ensure VSG operating in the designed U-Q droop by compensating the voltage droop of inherent droop feature of VSG and line impedance; The second voltage controller was designed to solve the problem of voltage quality caused by dispatching periodicity in the microgrid central controller, the randomicity of load disturbance, the discrepancy of first voltage control and so on. Finally, the proposed scheme is testified on the Matlab/Simulink platform.关键词
