摘要:

为了实现配电网运行经济性与可靠性的协调，提出一种基于进化规划算法的配电网运行方式定制方法。以定制周期内电能损耗最小为目标，以供电可靠性、潮流平衡、电压幅值、电流偏移等为约束条件，并计及配电网辐射型、无孤岛运行方式的约束，通过结合改进随机变异策略的进化规划算法对配电网开关状态向量进行寻优搜索，解决了考虑多种约束条件下配电网运行方式的定制问题。算例分析结果表明，该方法可在保证供电可靠性的基础上获取具有低电能损耗的配电网运行方式，对于科学地制定配电网运行计划，提高配电网运行管理的规范性，具有重要的意义。

Abstract:

In order to realize the coordination of economy and reliability of distribution network operation, a decision method of operation mode for distribution network based on evolutionary programming algorithm (EPA) is put forward. The minimum energy losses are taken as the objective, and the power distribution reliability, power flow balance, voltage amplitude, current offside, radiation and no-islanding are considered as the constraints during the selection of operation mode. The operation mode of distribution network considering multiple constraints is determined through searching the states of switches by using EPA combined with improved random mutation strategy. The example results indicate that an operation mode of distribution network and sufficient power supply reliability can be determined by the proposed method. The method has important significance to decide the operation plan and to improve the normalization of operation and management.

Key words: distribution network operation mode electric energy loss evolutionary programming algorithm decision method
