基于改进禁忌搜索的配电网重构

An improved tabu search for reconfiguration of distribution systems

在配电网的运行中,常需根据负荷的变化情况及时调整网络中的开关状态,以达到整个网络消除过载、损耗最小的目的。为了解决配电网优化重构问题,提出了一种改进禁忌搜索(TS)方法。该方法根据配电网在正常运行的情况下呈辐射状的特点,将同步开关法的思想用于TS优化编码策略中,以系统有功网损最小为目标函数对配电网进行重构。通过对典型系统的计算,结果表明该算法具有更高的搜索效率和可靠性。

Under the operation of distribution network, switches＇ status are usually altered according to the change of load power in order to diminish overload and minimize the transmission loss. To optimize distribution network reconfiguration, an improved method is presented and applied to optimize distribution network. In this method ,considering the features of distribution network, i.e., radial structure in normal operation, the principle of synchronous switch is used for TS to optimize the code tactics and the minimization of active power loss is used as the objective function. The presented method is conducted by typical testing system, the calculation result shows that the new method possesses better search efficiency and dependability.
