Application of Reactive Power Control in Grid-Connected Photovoltaic Power Generation
Reactive power control can be applied to grid-connected photovoltaic power generation,which is a key measure to ensure the stable operation of power grid.In this paper,an improved Voltage-Reactive Power(V-Q)control algorithm is proposed to control the grid connection of photovoltaic power generation,and the implementation of the control algorithm is discussed.This method can effectively improve the response sensitivity of photovoltaic power generation grid-connected system,prevent the system from oscillation and over-regulation,and reduce the harmonic level.Taking a photovoltaic power plant in northwest China as an example,this paper deeply analyzes the influence of the improved V-Q control algorithm with adaptive proportion-integration-differentiation(PID)controller on the stability of the system.The research results show that the algorithm can ensure the stable operation of photovoltaic power generation system and provide reference for other photovoltaic power plants.
