Voltage Control Strategy for Grid Converter Based on Droop Control
In order to improve the voltage stability of the system.Based on the traditional droop control,an adaptive droop control method based on the combination of active current and reactive current is proposed.The control strate-gy of microgrid composed by parallel network converter is introduced in detail.The droop controller is divided into three units is current(power)decoupling,first order differentiation and droop control.From the point of view of syn-chronous generator,the design principle of first order differential link and droop coefficient is analyzed.The"com-munication mechanism"of power sharing in parallel system of grid converter is analyzed and verified.Finally,a sim-ulation model is established,and the feasibility of the proposed method is verified by the simulation results.
