A NEW MULTI-OBJECTIVE ALGORITHM FOR DISTRIBUTION NETWORK RECONFIGURATION

Distribution network reconfiguration is an important content in distribution management system, which is a nonlinear combinatorial optimization problem in essence. It is difficult to obtain perfect results by traditional approach. A new algorithm for distribution network reconfiguration is proposed, which sufficiently utilizes and synthesizes load balancing method and branch exchanging method to improve load balancing process; and also uses a new partitioning power flow calculation method and a new heuristic rule deduced from the formula of branch exchanging network loss estimation, and resolves the multi objective distribution network reconfiguration problem properly. Theoretical analysis and numerical example show that the method is highly efficient and feasible, and conforms to the practical demands in distribution automation.
