Abstract

This paper presents an application of a multi-objective seeker-optimization-algorithm (MOSOA) for solving multi-objective design of advanced power distribution systems (PDS) considering fixed cost, non-linear variable cost and reliability as the objective functions including DGs (distributed generations) and D-FACT (distribution-FACT) devices. The proposed planning methodology uses contingency-load-loss index (CLLI) for reliability evaluation, which is independent of failure rate and fault repair duration of the feeder branches. To enhance the reliability and efficiency of existing PDS, planning strategy includes distribution automation devices such as automatic recloser (RA). Performance of the proposed approach is assessed and illustrated on a 54-bus PDS, considering real-time design practices. Furthermore, a qualitative comparison is made with NSGA-II, showing the efficacy of the proposed planning approach.
