Abstract
As an effective carrier of distributed generation,microgrid is an effective way to ensure the distributed power reasonable utilization.However,due to the mismatch of line impedance and other factors in microgrid,reactive power supplied by distributed generation units cannot be shared reasonably.In order to share the reactive power accurately,this paper proposes a reactive power-voltage control strategy based on adaptive virtual impedance.This method changes the voltage reference value by adding an adaptive term based on the traditional virtual impedance.Meanwhile,a voltage recovery mechanism is used to compensate the output voltage of distributed generator in the process.Simulations and experimental results show that the proposed controller can achieve reasonable sharing of active and reactive power of load,and the feasibility and effectiveness of the proposed control strategy are verified.关键词
