摘要
Abstract
With the increasing scale of wind farms,a wind farm can participate in grid voltage control by sending some reactive power. To reduce the active power loss and node voltage fluctuation caused by the reactive power flowing in the wind farm,a reactive power allocation strategy is proposed. Considering the internal topology of the wind farm,the ef?fects of the internal circuit distribution and electrical equipment parameters on the power flow are taken into account. To minimize the internal grid loss of the wind farm,the doubly-fed induction generator(DFIG)units are employed as a continuous reactive power source. Then,the particle swarm optimization(PSO)algorithm is used to solve the construct?ed reactive power model,thus realizing the reasonable allocation of reactive power output of each unit. Finally,a wind farm in Shandong Province is taken as an example,and the reactive power output of each unit is optimized,which re?duces the system’s active power losses and effectively improves the quality of node voltage.关键词
