Power System Restoration Based on Maximum Power Transfer using Dijkstra’s Algorithm

Abstract

The present paper studies the service restoration of the distribution network based on real power flow of the distribution lines using Dijkstra’s algorithm. The procedure is done to decrease the amount of load shedding and ensure quality of the voltage level under various outages and load conditions. The objective function in this paper is to maximize the amount of power restored with minimization of real power loss and the constraints of normal conditions of the distribution network. To crack this multi objective, multi constraint combinatorial problem, the methodology which is proposed has two steps. In step one Dijkstra's calculation is utilized to acquire the power flow path from the feeder to all the buses, which is based on maximum power transfer. Second step performs the load flow analysis. Based on the load flow analysis results the constraints are checked. The proposed methods are verified on 33-bus single feeder and 16-bus three feeder distribution network and the simulation results reveal their validity.
