Following the dissemination of distributed photovoltaic generation, the operation of distribution grids is changing due to the challenges, mainly overvoltage and reverse power flow, arising from the high penetration of such sources. One way to mitigate such effects is using battery energy storage systems (BESSs), whose technology is experiencing rapid development. In this context, this work studies the influence that the reactive power control dispatched from BESS can have on a real distribution feeder considering its original configuration as well as a load transfer scenario. The studied feeder supplies a soccer stadium (Mineirão), which has on its roof a photovoltaic generation plant of 1320 kWp, and the Federal University of Minas Gerais Campus—UFMG, where two BESSs with a total capacity of 1150 kVA/1750 kWh are yet to be installed. The aim of the analysis is to validate the use of active and reactive power injection provided by BESS in controlling the feeder losses and voltage profile. The methodology consists of analyzing typical load curves obtained from feeder measurement data and carrying out simulations considering the BESS injections. The power flow simulations are done using OpenDSS focusing in analyzing the influence of BESS injections. Specifically, the BESSs are used for power factor control, volt–VAR control and power factor correction, whereas the analyses are devoted to the feeder performance, namely losses and voltage profile.
