The coordination control of voltage and reactive power between wind turbines and SVC in large scale wind farm

The voltage and reactive power is controlled by both double-fed induction generator of constant voltage-control and SVC in wind farms. Firstly in this paper, the voltage and reactive power control principles of constant voltage-control double-fed induction generator and SVC are analyzed; secondly, mechanism analysis of coordination control was studied; finally, optimal control model of two devices was obtained through differential evolution algorithm, then coordination control is realized.
