Algoritmos microgenéticos e lógica difusa aplicados ao controle de bancos de capacitores em redes de distribuição.

Abstract

This work presents an artificial intelligent-based algorithm for the solution of the reactive power compensation problem. It intends to increase the computational efficiency of the genetic algorithms to turn them applicable to real electrical distribution systems. The reactive power compensation problem in a radial distribution system is formulated and solved by a hybrid algorithm. It uses a microgenetic algorithm in conjunction with fuzzy logic. The objective function includes economic savings obtained by energy and power loss reduction and the acquisition and installation costs of fixed and switched capacitors. The hybrid algorithm determines the capacity, location and control schedule of the capacitors banks. The results presented in this work are very promising.
