摘要

This paper presents a new solution approach to determine the optimal number and locations of both manual and automatic switches, with respect to probabilities of all feasible control sequences under contingencies. Furthermore, both transformer and bus failure rates are incorporated in the proposed problem formulation to reach more practical results. An artificial bee colony based algorithm is also introduced to solve the optimization problem. Besides, prevalent cost function formulation of switch placement problem is extended by incorporating operation probabilities of switches and the affiliated infrastructures. Bus number four of the Roy Billinton test system is employed to illustrate the effects of the proposed approach on distribution networks reliability. Moreover, performance of the developed algorithm is studied in several scenarios, and the obtained results are compared with those of previous methods. Detailed numerical results and comparisons presented in the paper show that the proposed solution approach could noticeably improve the obtained results with low computational burden; thus, it can be used as an effective tool for joint automatic and manual switch placement within practical distribution networks.
