【摘要】：为使得配电网重构更为合理而有效,提出一种配电网多目标动态重构新方法。以降低网损和减少开关操作次数为综合优化目标构建配电网多目标动态重构模型,采用基于图论中代数连通度的网络连通性判别方法快速消除无效解,采用基于独立环路的实数编码策略大幅降低变量维数。针对该复杂模型的求解,设计一种新型的复合型微分进化多目标优化算法,通过融合不同特点的变异策略,兼顾个体多样性和收敛速度,解决了群智能进化算法存在的寻优深度与速度之间的矛盾。最后以IEEE 33节点配电系统为例进行多目标动态重构,通过对求得的Pareto最优解集以及开关操作性价比进行分析,验证了该方法的有效性和优越性。
[Abstract]:In order to make the reconfiguration of distribution network more reasonable and effective, a new multi-objective dynamic reconfiguration method is proposed. The multi-objective dynamic reconfiguration model of distribution network is constructed with the objective of reducing network loss and reducing switching operation times. The network connectivity discrimination method based on algebraic connectivity in graph theory is used to quickly eliminate invalid solutions. A real number coding strategy based on independent loop is used to reduce the dimension of variables significantly. For the solution of the complex model, a new complex differential evolution multi-objective optimization algorithm is designed. By combining the mutation strategies with different characteristics, the diversity and convergence rate of individuals are taken into account. The contradiction between optimization depth and speed of swarm intelligence evolutionary algorithm is solved. Finally, taking IEEE 33-bus distribution system as an example, the multi-objective dynamic reconfiguration is carried out. The effectiveness and superiority of this method are verified by analyzing the Pareto optimal solution set and the switching cost ratio.
