Research on the Reactive Power Control Strategy in the Wind Power Integrated Region

This paper studied a reactive power control strategy in the wind power integrated region to stabilize voltage by controlling the reactive output of each wind farm. Firstly,the reactive adjustment quantity of the voltage control point was calculated and then the reactive adjustment quantities were distributed to each wind farm according to the optimal distribution rules of the reactive power source. This strategy made full use of the reactive regulating capability of the reactive compensation equipment in each wind farm so that all wind farms could be involved in the voltage stability control in the grid-connected region. Wind speed variation and voltage drop were simulated and the simulation results showed that the voltage variation could be effectively inhibited by this strategy.
