摘要
分布式电源(DG)的接入对配电网重构带来诸多影响,使含DG的配电网重构难以用传统模型来描述。为了充分发挥DG对配电网的有利作用,将DG视为可调度设备,建立了以网络开关组合、DG注入功率、DG位置为控制变量的配电网综合优化重构模型,采用量子进化算法(QEA),以网损最小为目标函数,对模型进行求解,降低了配电网的有功损耗。采用IEEE33节点测试系统进行仿真计算,结果表明了该方法是正确、有效的。
Distributed Generation(DG) brings lots of difficulty to network reconfiguration,making it hard to describe the problem while using the traditional model.In order to make use of the beneficial effect of DG,this paper establishes a integrated optimization configuration model regarding network switches、DG power、DG location as variables,and takes network loss as the objection,using quantum evolutionary algorithm(QEA) to solve the model.The effectiveness and correctness of the method proposed in this paper is verified through the simulation results of IEEE 33-node system.
