Research
His primary research interests include harmonic mitigation in renewable energy systems, control of power converters, and the integration of renewable energy sources into the grid.
Research Background:
- Oil immersed converters: Development of a prototype for a two-level three-phase converter immersed in oil, aiming to enhance the thermal and dielectric characteristics of the converter. Oil-immersed converters applied in medium-voltage systems
- Study of Modulation Strategies: Development of a Matlab/Simulink platform for testing Two- and Three-Level Converters,in Three- and Four-leg Converters. Utilization of Space Vector Pulse Width Modulation (SVPWM) Technique.
- Control Strategy for Two-phase Three-wire Converters: Use of the Conservative Power Theory to adequately synthesizing control references for a PV-based multifunctional inverter operating in a two-phase three-wire grid, providing flexible controllability to supply loads’ active current.
- Development of a Smart Battery System: Development of a pilot plant consisting of a microgrid with distributed generation, loads, and various battery banks. Commissioning of the pilot plant installed at the School of Engineering of UFMG. Comparative study and selection of battery technologies most suitable for photovoltaic power generation. Study and development of control alternatives for distributed generation and storage systems in a microgrid scenario.
