A two-level optimization method is presented to find the optimal number and location of conventional protective devices be upgraded remote-controlled switches (RCSs) for an existing distribution network (DN). The effect distributed generation (DG) on this problem considered. In first level, a nonlinear binary program proposed maximize restored customers subject technical topological constraints. All feasible interchanges between ties involved in restoration, when fault occurs at all possible locations are found considering switching dependencies. second cost function, combining expected interruptions (ECOST) switch cost, minimized with respect RCSs. function computed based optimum restoration policies obtained from level. placement RCSs using algorithm tested 4-feeder 1069-node test system compared solution genetic (GA) same system.
