摘　　要：通过传统发电机输出功率定义有功功率流动系数,对风电场-抽水蓄能站进行统一调度,由该系数与风电场输出功率比值来决定风电的功率消纳策略。以传统发电机输出功率波动最小作为目标函数,建立跟随电网负荷变化的抽水蓄能站发电优化调度模型,采用改进的非洲野狗算法对系统进行优化,并在算法中加入动态迭代步长,旨在算法前期加快迭代速度、在算法后期增强计算精度。仿真结果证实了所提优化运行策略在系统运行中的有效性与可行性。By defining the active power flow coefficient based on the output power of traditional generators,the unified scheduling of wind farm-pumped storage stations is carried out.The power consumption strategy of wind power is determined by the ratio of this coefficient to the output power of the wind farm.A pumped storage station power generation optimization scheduling model is established with the objective function of minimizing the fluctuation of traditional generator output power.The system is optimized using the African wild dog algorithm with Gaussian mutation operator,and a dynamic iteration step is added to the algorithm to accelerate the iteration speed in the early stage and enhance the calculation accuracy in the later stage.By comparing simulation results,the effectiveness and feasibility of the optimization operation strategy proposed in the article in system operation have been confirmed.
