Controle Volt/VAr utilizando geração distribuída em redes de distribuição

Abstract

This document presents a centralized strategy of voltage control and reactive power (Volt/VAr) to a distribution system using concepts of smart grids. The methodology developed acts as an intelligent control module of the equipment arranged in the distribution system, which are capacitor banks, voltage regulators and transformers. Voltage levels depend on the reactive power ux of the electrical system, distributed generation will act as a regulating device voltage for the Volt/VAr control, by having reactive power injection/absorption system capacity.With the completion of Volt/VAr control, it has improved voltage levels, reduction of power losses under normal operating conditions and also increases the lifetime of the distribution system equipments. The solution of Volt/VAr control problem is based on fuzzy logic, which seeks to joint and coordinated optimization of existing control equipment in the system. The results show to be e_cient with distributed generation acting as a voltage control device and are presented to a test network IEEE 34 bus.
