Estudo de compensação de reativos por banco de baterias

Abstract

Electrical distribution networks are responsible for delivering stable energy to their consumers, however, due to the gradual growth of loads, in many scenarios, low voltage occurs in the network, which even causes the loss of equipment for the consumers it serves, which ends up providing new alternatives. to overcome the problem, making the implementation of a battery bank (BESS) more viable, compensating reactives in the network according to the region's needs, making progress in this emerging technology. This work's main objective is to analyze ways of using BESS as a source of reactives for the network, helping to increase voltage. This methodology consists of dividing it into three main stages, with the first analyzing load levels in search of undervoltage, and the second adjusting the best time for adjustment using a daily discharge curve. In the third stage, two reactive compensation approaches are verified, enabling the study. The test methodology is verified using the OpenDSS software, in a 4-bar IEEE test system consisting of three loads maintaining their demands in order to analyze the impacts caused by distributed generation (DG) and the best use of BESS manipulated in different conditions .
