摘    要:为解决配电网的重构问题,提出了一种改进的禁忌搜索(Tabu search)方法.该方法结合配电网络的闭环设计和开环运行的特点,将遗传算法中的优化编码技术引入到Tabu搜索算法中,并以有功网损最小为目标函数对配电网络进行优化.对3个典型IEEE测试系统进行了优化计算,将其结果与模拟退火算法和遗传算法的计算结果进行比较证实,改进的Tabu搜索算法比模拟退火算法和遗传算法具有更高的搜索效率.

关 键 词:电力系统  配电网重构  禁忌搜索  组合优化  输配电工程

Abstract:To deal with distribution network reconfiguration, an improved Tabu search method is presented and applied to the optimization of distribution network. In this method, considering the features of distribution network, i.e., interconnected meshed network in design and radial tree structure in operation, the optimal encoding method in genetic algorithm (GA) is led into the Tabu search algorithm and the minimization of active power loss is used as the objective function. The optimization calculations of three typical IEEE testing systems by the presented method are conducted and the calculation results are compared with those by annealing algorithm (SA) and GA respectively. The comparison results show that the improved Tabu research algorithm possesses better search efficiency than GA and SA.
Keywords:Power system  Distribution network reconfiguration  Tabu search  Combinational optimization  Transmission and distribution
