Utilização de sistemas armazenadores de energia para controle do perfil de tensão em regime permanente em redes elétricas de distribuição

Abstract

This work aims to implement a study for the analysis of a performance of an energy storage system using Li-ion battery. For this, a tool of the software MATLAB, version 2016a, Simulink was used. The study mentioned elaborates a switching control of the battery system using a voltage level control of the grid, using the high and low limits disposed on Módulo 8 of Procedimentos de Distribuição de Energia Elétrica no Sistema Elétrico Nacional – PRODIST, from Agência Nacional de Energia Elétrica – ANEEL. The study provides a methodology for the analysis of the problem, the choice of the most interesting technology, considering the technical and economical factors and the bank capacity sizing. In order to extend the lifetime of the battery, a strategy to limit the discharge current was implemented and also the monitoring of the State of Charge – SoC of the battery. To dispatch the energy storaged in the battery, a two level voltage converter was used for it. Also, a DC/DC converter based on the Boost converter topology was used, its control was based on the information described above. To control the recharge of the bank – battery, a AC/DC converter based on controlled 6-pulse rectifier with Thyristors was used, with its charge control made with a control command connected to a DC/DC converter using Buck topology For the analysis of the arrange developed the 13 bus bar distribution test feeder of Institute of Electrical and Electronics Engineers – IEEE will be used.
