摘要
提出使用改进模拟植物生长法求解配电网络重构问题。该算法充分考虑植物生长过程中的智能化因素,避免了搜索过程中的随机机制,缩小了搜索空间,减少了迭代次数。以未来一段时间内网损最小为目标函数,建立配电网重构的数学模型。根据配电网的结构特点,以基本环路为单位形成可断开关集,避免了一些不可行解的产生,降低了变量的维数,提高了搜索效率。通过对IEEE69节点测试系统的计算和分析表明,该方法在解决配电网络重构问题上具有很高的搜索效率和寻优性能。
Distribution network reconfiguration using improved plant growth simulation algorithm is proposed. The algorithm fully considers the intelligent factor in the process of plant growth. It can avoid random mechanism in searching process, which compresses the searching space and reduces the iteration number. This paper selects minimum network loss in the near future as objective function to establish the mathematical model of distribution network reconfiguration. According to the characters of distribution network, the sets of switches are formed that can be opened by basic loops. It can avoid the production of the infeasible solutions, which dramatically reduces the dimension of variable and improves the efficiency of calculation. The test result on IEEE 69-bus distribution network shows the prominent efficiency and significant global optima searching performance.
