Reactive power and voltage coordinated control research of wind farm adopting doubly-fed induction generators

摘要

For the wind power grid voltage control problem, this paper proposed a reactive power and voltage control strategy by coordinate the wind farm reactive power source. Considering wind internal loss and the machine voltage deviation, established a optimal control model and a objective function, using the improved particle swarm optimization (PSO) algorithm to solve the function, the control strategy can reduce the wind internal loss and stabilize the voltage of the machine on the basis of meet the requirements of PCC voltage. The example simulation proved the effectiveness and economy of the control strategy.
