Research on Voltage Stability of Large-scale Integration of Wind Power

Abstract

Large-scale integration of wind power will affect the static voltage stability of the power system. Through the power flow calculation of the regional power grid with wind turbines, the voltage stability of the power grid connected to the wind farm is analyzed based on the P-V curve method. Moreover, the variation of voltage is analyzed by changing the control mode of the fan and adding the reactive power compensator. The results show that the voltage stability of the constant voltage control mode is better than that of the constant power control mode, and the voltage level is obviously improved after adding reactive power compensation.
