ABSTRACT: Continuity in power supply for the consumers is a permanent concern from the utilities, pursued with the development of technological solutions in order to improve the performance of network restoration conditions. Using remotely controlled switches corresponds to one possible approach to reach such an improvement and gives some convenient remote resources, such as the fault detect, isolation, and transfer loads. This paper presents a methodology implemented in a computer programming language for allocation of these devices in electric distribution systems based on the analytic hierarchical process (AHP) method. The main contributions focus on considering the impact of installing remotely controlled switches in the reliability indices and the AHP decision-making algorithm for the switches allocation. The effectiveness of the proposed algorithm is demonstrated with case studies involving actual systems of the AES Sul utility located in Southern Brazil.

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.

The best option for the load transfer using remote-controlled switches, after contingencies, will be defined based on multicriteria decision making. The effectiveness of the proposed algorithm is demonstrated with case studies involving actual systems.
