【摘要】 通过求得光伏电站有功功率的期望值解决了其有功输出不确定的问题,并通过调整光伏并网系统的有关参数来调节其无功输出,使得光伏电站能够参与配电网的无功优化。建立了以网损最优为目标的函数模型,并用改进的细菌群体趋药性算法(bacterial colony chemotaxis,BCC)求得目标函数的最优解。通过实例计算分析,验证了该模型和算法的有效性。更多还原

【Abstract】 In this paper,the problem of PV power station’s active output uncertain is solved by calculating expected value of the active power. By adjusting the related parameters of PV connected system to regulate the reactive power output,so to keep the PV power station can involve in reactive power optimization of distribution network. Function model with the smallest network loss as objective is established and the optimum solution of objective function is obtained by the use of modified Bacterial Colony Chemotaxis( BCC) algorithm. The validity of the model and algorithm is verified through calculation and analysis of real examples.更多还原
