摘要
针对配电网网络重构问题,在考虑配电网电压稳定的前提下,提出了降低配电网网损的目标函数,利用蚁群算法正反馈的特性,将其应用于配电网重构中,并设置中心控制蚂蚁搜索当前最优解作为各条边信息素更新依据。为满足配电网辐射状结构要求,结合P rim算法,使蚂蚁一次遍历对应一个辐射网形,即一个有效的开关组合,大幅度缩小了问题的解空间。实例证明采用的蚁群算法可以得到较文献[1]网损更小的配电网重构方案,且重构后的系统在处理负荷增大问题上较重构前系统有更好的调控能力,系统稳定性得到提高。
An ACS (ant colony system) algorithm is proposed in the paper to solve the problem of distribution network reconfiguration which is a multi-objective optimization problem. Considering voltage stability of distribution network, setting the objective function to be loss minimization, the proposed method puts a control ant to refresh pheromone. Prim algorithm is used to make a mapping between a traverse of an ant with a validity switch combination. Case study shows that the proposed method is efficient and can give better result than the method proposed in[1].
