Abstract

The steady-state power flow equations are the basis for every computational problem related to power systems. One of these problems is the service restoration problem, which should be solved to reenergize out-of-service loads. In this paper, a two-stage power flow model is presented for electrical distribution systems. The two-stage power flow model can be applied to solve the service restoration problem in electrical distribution systems based on any heuristic or meta-heuristic method generating the state of switches and zones as a sequence of binary digits. Moreover, to minimize the number of non-faulted out-of-service zones and nodes while considering technical constraints, each topology generated by a heuristic or meta-heuristic method is evaluated and ranked using the proposed two-stage power flow model. Therefore, the highest-ranked topology is selected as the optimum topology. Finally, a meta-heuristic method is used to address the restoration problem on a 44-node test system, demonstrating the effectiveness and practicality of the proposed method.
