摘要:
合环操作在提高供电可靠性的同时也可能导致过大的合环电流,对配电网的安全稳定运行产生冲击。文章针对10 kV配电网合环电流调控问题,提出了一种基于改进多目标和声优化算法的综合调控策略:以调节变压器分接头和投切电容器组为优化手段,兼顾合环操作的安全性与经济性,将合环电流最小、合环网络损耗最小作为目标函数,建立了合环电流综合调控模型;利用基于动态参数及Pareto最优解的改进和声算法求解模型,并利用递归算法求解计及过程安全性的调控元件动作顺序。最后基于Matlab/Simulink平台对某实际合环算例进行仿真,结果表明,相比于传统和声搜索算法,本文所提算法获取全局最优解的能力更优。
Abstract:
The loop closing operation may lead to excessive current which could lead to an impact on the safe and operation stability of the distribution network, although it can improve the power reliability. To solve the problem of loop closing current adjustment in 10 kV distribution network, a comprehensive control strategy based on improved multi-objective harmony optimization algorithm was proposed in this paper. A comprehensive control model of loop closing current, which considers the safety and economy of loop closing operation, is established to realize the objective of minimal loop closing current and minimal power loss by adjusting transformer taps and switching capacitor banks. An improved harmony algorithm based on dynamic parameters and Pareto optimal is used to solve the model, then a recursive algorithm is used to solve the action sequence of control elements considering process security. Finally, simulation based on Matlab/Simulink platform was performed for a practical case of loop closing operation, and results show that the proposed algorithm has better ability to achieve global optimal solution compared with the traditional harmony search algorithm.
