摘　　要：针对含可调度式分布式电源的配电网优化问题,提出一种基于均匀网络理论的配电网协调优化方法。首先通过基尔霍夫电压和电流定律,建立出以网损最小为目标的网络均匀性条件;其次,提出均匀网络逼近算法解决电源出力的约束问题;最后,结合提出的高效单环网重构算法,给出考虑电容器投切、重构和可调度式电源优化的配电网协调优化算法。算例首先验证了均匀网络逼近算法的准确性,在此基础上,采用IEEE33标准节点系统验证了方法的高效性和实用性。This paper proposes a coordinated optimization method based on uniform network theory for joint optimization including dispatch DG in distribution networks.The uniform network condition is established via minimization network losses objective and KVL and KCL laws.The output constrains of DG is solved by approaching uniform networks algorithm.The coordinated optimization algorithm considering capacitor switching,reconfiguration and dispatched DG is solved by efficiently reconfiguration with single loop.The accurate of uniform network algorithm is verified.The efficiency and practicability of the method are verified by the IEEE33 standard node system.
