Hierarchical Reconfiguration Optimization of Distribution Network Considering Multiple Indexes

With the enlarging scale of distribution network and increasing access users, distribution network has more and more complicated wiring. The existing adjustment methods based on manual operation are not only inefficient, but are also difficult to provide optimal adjustment solution. In this paper, hierarchical reconfiguration of distribution network involving multiple indexes is proposed to establish a mathematical optimization model for network reconfiguration. Examples are analyzed using a typical regional distribution network. The examples indicate that this method can reduce part of unnecessary reconfiguration analysis, and when there is need for the network to perform reconfiguration calculation, the method achieves a good optimization effect in the calculation. This optimization method can improve and optimize the distribution network in terms of economy, safety, reliability, etc.
