Coordinated Dispatching and Frequency Control Strategy of Power Systems with Large Scale Wind Power Penetration

In this paper, a coordinated dispatching and frequency control strategy is presented for wind turbines (WTs) participating in frequency regulation from three levels. Firstly, the coordinated dispatching and frequency control strategy among multi-source power generation systems is given with the aid of the wind power installed capacity penetration rate; Secondly, the coordinated distribution strategy among the wind farms is presented by combing the incremental active power reference with parameters tuning method; Thirdly, the coordinated control is investigated by integrating droop control, inertia control and de-load control for each WT. Simulation results demonstrate that the proposed coordinated dispatching and frequency control strategy can obtain better frequency regulation performance for power systems with large scale wind power penetration.
