A Hybrid Application Based on Expert Knowledge for Solving the Switches Placement Problem in Distribution Networks

[摘要] In planning a distribution network, after routing newly feeders, optimal placement of sectionalizers and tie switches is an important task. However, it is very difficult for planners to select the optimal place of tie switches and sectionalizers, because too many candidate locations exist. In this paper, tie switches and sectionalizers placement problem on radial distribution networks are formulated, and a microgenetic algorithm (MGA) in conjunction with fuzzy logic (FL) is proposed as solution. A FL is used to apply expert knowledge that takes into load priority and failure rate and a MGA is used to considerate reliability indices. The costs associated with installation of switches are shown. A 104-bus test system is presented and the results are compared to the solution given by other techniques. This comparison confirms the efficiency of the proposed method which makes it promising to solve complex problems of tie switches and sectionalizers placement in radial distribution networks...
