João Alberto Passos FilhoWesley PeresThis paper presents two new steady-state voltage control methodologies for microgrids. The main idea is to use the power factor angle of photovoltaic (PV) inverters to develop two control schemes, a primary one for local voltage control at the interconnection point and a secondary one for voltage control through the coordinated adjustment of several PV generation units. Mathematically, the proposal is based on a set of non-linear equations that represent the equations of the grid, the PV system model, and the proposed control schemes. These equations form a generalized and expanded power flow problem, which can be solved efficiently by the traditional Newton-Raphson method. Complementarity conditions and sigmoid functions are used to treat the inverter limits, carried out automatically and simultaneously with the problem’s solution. Computational simulations carried out on a small-scale tutorial system and the IEEE 38-bus system demonstrate the effectiveness of the methodologies. In addition, the performance of the secondary control scheme was evaluated under different load, irradiance, and temperature conditions, considering a time horizon of 7 days (168 hours). The results indicate that the developed control has great potential to improve the voltage profile of microgrids.
About Me
Holds a Bachelor's degree (2010), a Master's degree (2012), and a Ph.D. (2016) in Electrical Engineering from the Federal University of Juiz de Fora. Currently an Associate Professor IV in the Department of Electrical Engineering at the Federal University of São João del-Rei (since 2014), teaching undergraduate and graduate courses (PPGEL, since 2017). At PPGEL/UFSJ/CEFET-MG, he has been the deputy coordinator since July 2024 and the local coordinator of PPGEL at UFSJ. He was a full member of the board representing the Electrical Systems area from July 2018 to June 2024. At UFSJ, among other administrative roles, he is one of the Engineering coordinators of the Scientific Initiation Chamber at the Research Dean’s Office. Additionally, he is a member of the Graduate Affirmative Actions Management Committee at PROPE/UFSJ (2025-2027).
An IEEE member since 2014, he was elevated to Senior Member in 2022 and served as Vice-Chair of the IEEE Minas Gerais Section (2022-2023). He is currently the Chair of the IEEE MG Section (2024-2025).
