Distribution Network Reconfiguration Based On Particle Swarm Optimization

Distribution network reconfiguration is the important measure of optimal operation of distribution systems, which may bring out great benefit both in economy and in society. The paper proposed a new approach for distribution network reconfiguration based on Particle Swarm Optimization which is a novel intelligent optimization algorithm. That is significant not only to solve the problem itself but also to develop the intelligent technology in the new field.Distribution network reconfiguration covers with many aspects, such as load forecast, flow calculation, optimum objective selection, and search technology. The paper emphasized on optimization technology study, and did some research on network modeling, topology analysis, and flow calculation.Firstly, an applied power flow algorithm of distribution network with topology structure identification was developed. Simple model of distribution network was build based on speciality of the problem and emphasis of the research. The node class, the branch class, the layer class and the feeder class were defined to dynamically show the distribution network. Bread first search strategy was employed to identify changes of topology structure. Hierarchy of distribution network was utilized to modify backward/forward power flow algorithm, which could calculate branch currents and node voltages in the same layer simultaneity.Secondly, a novel distribution network reconfiguration algorithm based on...
