Automatic Reestablishment of Power Supply in Distribution Systems using AHP Method

Abstract- The continuity of electric energy supply to consumers is a permanent objective of the power utilities, pursuing the development of technological solutions to improve the performance of the power re-establishment in contingency conditions. The main purpose is to minimize the impact on the number of consumers affected and reduce the time required to re-establish the energy supply. In this way, the power utilities have been employing efforts for the automation of distribution networks in order to reestablish power in a more agile way, resulting in better indexes of continuity and increase consumer satisfaction. Therefore, the purpose of this paper is to develop a methodology to reestablish the electric energy supply by using remote-controlled switches, regarding the validation of the technical viability for distribution networks reconfiguration in real time by means of computational simulations. The best option for the load transfer using remote-controlled switches, after contingencies, will be defined based on AHP method. The effectiveness of the proposed algorithm is demonstrated with case studies involving actual systems.
