Research on Coordinated Control of Reactive Power and Voltage in Large Scale Wind Farm Groups

Abstract:

Under the influence of the view that reactive power compensation on-spot, the study on control of reactive power and voltage in wind farms focused on a single wind farm optimal reactive voltage control. China's wind power resources are relatively concentrated and a region often have several or even a dozen wind farms. Wind farm thought as a unit to adjust often leads to irrational reactive power flow. Wind farm groups and collection substations must be thought together as a whole to manage. This paper makes use of collection substations to support area voltage, coordinates reactive power output of the wind farm groups based on the voltage sensitivity and improves the overall grid voltage level of the wind farm groups areas. Simulation results proved that the program can improve the regional power grid voltage level.
