摘要
针对光伏电站并网运行给配电网无功优化带来的问题,根据光伏发电的运行特性,构建了含光伏电站的配电网无功优化数学模型,并提出改进的布谷鸟算法求解无功优化模型的方法,对含光伏出力的IEEE-33节点配电系统进行无功优化。结果表明,所提出的改进算法能有效降低配电网的有功网损,各节点远离电压崩溃点。
For reactive power optimization problems of photovoltaic grid connected system,according to the operating characteristics of PV power generation,the mathematical model for reactive power optimization of distribution network with PV station was established.And then an improved cuckoo search algorithm was proposed to solve reactive power optimization model.The method was applied to the optimization problem of IEEE-33 node distribution system with PV power generation.The results show that the improved algorithm can effectively reduce the power loss of distribution network,and the nodes are far away from the voltage collapse point.
