摘要：
A multi-objective dynamic distribution network reconfiguration method is proposed to improve its rationality and effectiveness. The reconfiguration model is built, which takes the minimum network loss and switching frequency as its comprehensive optimization objective. The network connectivity discrimination method based on the algebraic connectivity of graph theory is adopted to quickly eliminate the ineffective solutions. The real number coding strategy based on the independent loop is used to significantly reduce the variable dimension. For solving the complex model, an optimal, compound, multi-objective differential evolution algorithm is designed, which integrates different mutation strategies and considers both individual diversity and convergence speed to solve the contradiction of group smart evolution algorithm between the searching depth and optimization speed. As an example, the multi- objective dynamic reconfiguration of IEEE 33-bus distribution network is carried out. The optimal Pareto solution set obtained and the performance-cost ratio of switching operation are analyzed, which demonstrates the effectiveness and superiority of the proposed method.
