【摘要】：为了提高配电网运行的经济性,提出一种基于图解蚂蚁系统的配电网动态重构问题的求解方法。求解过程分为离线和在线两个阶段。离线阶段完成拓扑分析,形成同时包含配电网拓扑结构和时段长度两部分的可行解解集,用构造图表示。在线阶段通过模拟蚁群在构造图中的行走过程完成搜索寻优。离线阶段仅需完成一次拓扑分析即可支持在线阶段各时段拓扑结构的求解。在线阶段通过时段延伸方法将搜索空间由可行解解集缩小为较优解解集。仿真算例验证了提出的算法可以有效缩小搜索范围,找到最优解。
[Abstract]:In order to improve the economy of distribution network operation, a solution to the dynamic reconfiguration problem of distribution network based on graphical ant system is proposed. The solution process is divided into two stages: off-line and on-line. A set of feasible solutions including both topological structure and time length of distribution network is formed. By simulating the walking process of ant colony in the construction map, searching and searching optimization can be completed in the online stage. In the off-line stage, only one topological analysis can be completed to support the solution of the topological structure in each period of the online stage, and the on-line order can be obtained. The search space is reduced from the feasible solution set to the optimal solution set by the time extension method. The simulation example shows that the proposed algorithm can effectively narrow the search range. Find the optimal solution.
