摘要
配电网网络重构是配电网自动化系统的一个重要组成部分,给电力的供应提供了可靠性,给电力操作提供了灵活性。配电网网络重构的解是一组开关的组合,网络重构的目标多种多样,在实际应用中如何选取适合不同的配电网络重构方法是研究的目的。重点在启发式搜索和前推回代的配电网潮流计算方法的基础上以系统网损最小为目标函数来优化配网结构。首先生成一个1×N阶描述配电网开关通断的矩阵,然后以网损不能再减少为目的对所有的联络开关进行搜索,而寻找全局最优解。
Reconfiguration of distribution networks, which is a key function of distribution automation system, is an important guarantee to enhance reliability of power supply and flexibility of power operating condition. Solution of reconfiguration of distribution networks is a set of combination of switch, objects of reconfiguration for distribution networks are multifarious. How to apply the proper reconfiguration method in real application is emphasized. Distribution network optimization is realized by it taking least system network loss as the objective function based on heuristic search and forward/backward sweep method power flow algorithm. First, according to structure of distribution networks and information of switch create an 1 ×N matrix, than search all of tie switch in the light of network loss cannot again reduce. And finally it seek overall and optimal solution.
