基于解空间高效编码的配电网重构连续化算法
Continuous Algorithm for Distribution Network Reconfiguration Based on Efficient Encoding of Solution Space
摘要
Abstract
This paper proposed a continuous algorithm for distribution network reconfiguration (DNR) based on efficient encoding of solution space.By estimating the exchange range of switch exchange through deduced approximate formula of network loss,the solution space was compressed and the efficiency of op-timization was improved.To avoid directly solving discrete variables,a double-population solution space including discrete variables and continuous variables solutions was established,which can reduce the a-mount of calculation and is suitable to apply continuous variable optimization method to solve DNR prob-lem.After reducing the radius of the confidence interval variables,two kinds of non-effective solutions were avoided,and the number of times of power flow calculation was also decreased.The improved criss-cross optimization algorithm improves the convergence speed and precision.Simulation results verify the correctness and effectiveness of the proposed algorithm.关键词
