Algoritmo BVNS Aplicado no Problema de Restauração de Redes de Distribuição de Energia Elétrica, considerando Programa de Resposta da Demanda

ABSTRACT

In this work, a model based on the BVNS (Basic Variable Neighborhood Search) solution technique is proposed to solve the problem of restoring electrical energy distribution systems, considering in the model the participation of customers who are part of a demand response program and that can contribute to the restoration process allowing a number of its loads to be disconnected by the utility. The mathematical model consists of minimizing the cost of energy not distributed in the system due to unrestored sections, added to the remuneration costs of customers who are part of the demand response program, subject to the technical, physical and operational restrictions of distribution networks. This is a mixed integer nonlinear programming problem in which solution proposals are obtained through the BVNS algorithm. The neighborhood structure of the BVNS algorithm is based on the Node-Depth Representation technique. In this restoration process, carried out by the BVNS algorithm, for each solution evaluated, if any restriction is violated, a Genetic Algorithm is processed to perform load cuts in the sections with customers who are part of the demand response program. To test the efficiency of the proposed model, test results on a 53-section distribution system are presented.
