Multi-Objective Optimal Configuration of Multiple Switchgear Considering Distribution Network Fault Reconfiguration

The power supply and distribution network of prosumer group is equipped with contact switch section switch. After feeder fault occurs, the topological structure can be adjusted by changing state each in system, so as to realize reconstruction after fault, restore free area. optimal configuration different types switchgear appropriate position reduce time location isolation, further reconfiguration which greatly improves reliability for group. This paper introduces a series Boolean expressions describe existence switches network, then determines corresponding load interruption according types. On this basis, model established. By minimizing investment cost loss, multi-objective optimization index Finally, proposed tested through RBIs bus 4 network. test results show that solution effectively cost, improve maximize income.
