Multi-objective distribution network reconfiguration based on system homogeneity

Distribution network reconfiguration is a multi- objective and discrete nonlinear combinatory optimization problem. In this paper, a novel multi-object distribution network reconfiguration method is proposed based on system homogeneity. Firstly, the relationship between power loss and reliability of systems with different homogeneity is analyzed. Then, to enhance system reliability and homogeneity, a new multi-objective model is established by coupling the reliability index with system homogeneity. Based on the adaptive settings and fast iteration method, an improved multi-objective harmony search algorithm is proposed to solve the model. The test results on the 33-bus system show that the proposed method is corrective and effective.
