Switch Deployment in Distribution Networks

This chapter presents the optimal switch deployment in distribution systems. First, an explanation regarding different types of switches and their functionality is introduced. Then, a fundamental description of fault management procedure in distribution networks is presented. Thereafter, the mathematical formulation of optimal fault management process is described. Optimal switch deployment problem is formulated in the format of mixed integer programming (MIP). The impact of remote controlled switch (RCS) and manual switch (MS) is scrutinized on the interruption cost once they are installed either individually or simultaneously. The concept of switch malfunctions is explained and the influence of this issue on the optimal solution of the problem is discussed. Finally, the effect of uncertain parameters such as failure rate and repair time on the solution of switch deployment problem is investigated. It was shown that the uncertainty imposes a significant risk on distribution companies (DisCos).
