基于渔夫捕鱼优化算法的配电网络重构

针对正常运行条件下配电网络重构问题,提出一种基于模拟渔夫捕鱼寻优算法(SFOA)的配电网络重构算法。以有功网络损耗最小为目标函数,建立配电网络重构的数学模型,并采用易于编码实现、寻优能力较强的渔夫捕鱼算法对重构模型进行求解。根据配电网络的特点,应用一种基于网孔开关的编码策略,在不背离算法本身搜索方法前提下,简化移动搜索和收缩搜索,以实现对解空间的全局搜寻。最后利用Visual C++对IEEE-33节点算例进行重构,结果表明,提出的方法是有效可行的。

Reconfiguration of Distribution Network Based on Optimization Algorithm on Simulating the Fisher Fishing

For reconfiguration of distribution network under normal operating conditions, a novel method is proposed which is based on optimization algorithm simulating the fisher fishing (SFOA). The minimization of active power loss is used as the objective function, a mathematical model of distribution network reconfiguration is established, and then adopted SFOA which encodes easily, strong ability to obtain the optimal distribution network. According to the characteristics of the distribution network, a coding strategies based mesh switch is applied, simplified the moving search and shrinking search without departing from the search algorithm itself to achieve a global search for the solution space. Finally, used Visual C for the IEEE-33 node examples reconfiguration, result shows that the proposed method is feasible and effective.
