Research on Active Power Automatic Control Strategy of Wind Farm Energy Station Access System

摘要

Wind farms are included in the grid Automatic Generation Control(AGC)will help for power system control.In order to minimize the imbalance between the active output of wind farm and the reference value,a power automatic control strategy for wind farm was proposed in the paper,which is considered the dispatching of safe operation of grid and the number of start and stop of wind turbines.The wind turbines in the wind farm were divided into three different categories according to the output characteristics and operation state of the wind turbines.By combining with the energy storage control of wind farm,the selection of power regulation turbines was carried out while considering the constraints such as the climbing rate and the power distribution value of the wind turbines,the proposed method effectiveness was verified with simulation example analysis,which could take Ml account of the individual information of wind turbines and make the output power adjustment of wind farm reach the optimization effect both in economy and safety.
