Coordenação Volt/Var em Alimentadores de Distribuição Utilizando Lógica Fuzzy

Abstract

This paper presents a methodology to voltage coordination in distribution system using a cascade of Mamdani Fuzzy Controllers. The control devices considered are On-Load Tap Changer - OLTC and capacitor banks in substation, and Line Drop Compensator - LDC and capacitor banks along of feeders. The system can assess the control effectiveness for the distribution system operating on radial or meshed networks, and considering the inclusion of distributed generation. The system demand is modeled using a load curve. To illustrate the methodology performance it is used a system operating with different topologies.
