Abstract
In order to improve and solve the problems of local voltage stability,reactive power margin,etc.after integrating large-scale wind farm into power grid,the model for the reactive power coordination of wind farm equipped with the double-fed induction generator (DFIG) and the static VAR compensator (SVC) is established based on the actual operation condition of a wind farm,while a multi-object control strategy with the comprehensive consideration on the coordination between them is put forward as well.On the basis of the measured data of all the nodes within the wind farm,the multi-object optimal control model for the best voltage stabilities of all the nodes including the points of the common coupling (PCC) of the wind farm and the largest overall reactive power margin is derived with the improved chaos ant colony algorithm by the coordination strategy,so as to meet the real-time requirement of the algorithm,and thus improve the voltage level of the local power grid including the PCC busbar and increase the reactive power margin within the wind farm.The result of the simulation made by taking a wind farm in the Northwest China as the actual case shows that the reactive voltage coordination control strategy can better improve the local voltage stability of the wind farm,and then increase the reactive power margin in that region.关键词
