Algoritmos genéticos para localização e ajustes ótimos de reguladores de tensão em sistemas de distribuição.

Abstract

This work deals with the localization and optimal adjustment of tri-phase voltage regulators and single phase regulators banks in radial distribution systems. Low and peak system loading conditions are considered. This problem is solved using an Genetic Algorithm which minimizes the bar voltage deviation related to the system rated voltage and losses reduction with the regulators installation. The operation taps and the regulators localization are assumed as discrete variables. The load flow calculation is made with the Power Summation Method and a constant power modeling is used for the load representation. The implemented algorithm is validated by study of a distribution system presented in technical literature. In addition, an analysis of a regional distribution system is presented.
