The rapid development of power electronics is associated with the rising needs for renewable energy, electric mobility, and intelligent power systems. Under these conditions, collaboration at an international level becomes essential for researchers trying to participate in the development of the area. For many graduate and undergraduate students as well as young researchers in Latin America (IEEE Region 9), lack of funds usually hinders their ability to attend conferences on the international, or even regional, level. This problem is solved by the IEEE PELS ACE Travel Grants, which provide financial assistance to active members of the IEEE PELS, who are the first authors of conference papers. Besides the assistance, which is provided by the program, attendance of these conferences has its own value because it allows participants to present their research and make connections with other researchers.
The increasing integration of renewable energy sources into power grids requires adaptive strategies to maintain stability, especially in island and distribution grids. This article presents the development of a 200 kVA battery inverter with grid-forming control for the integration of photovoltaics (PV) into island grids. The inverter uses a three-phase Active Neutral Point Clamped (ANPC) topology with two interleaved legs and a DC-DC converter with flying capacitor topology. According to grid connection standard VDE-ARN 4105, PV systems must disconnect from the grid in the event of unintended islanding. However, the integration of renewable energy is crucial for future grid reliability, especially in isolated or disaster-affected regions. The energy management system aims to integrate PV systems into the grid during island grid operation, prevent battery overcharging, and ensure grid-serving functionalities. Using the VDE 4105 guidelines, the system controls PV active power by adjusting the grid frequency and optimizes the battery’s state of charge (SoC) for reliability and durability. Power-Hardware-in-the-Loop (P-HiL) laboratory tests demonstrate the effectiveness of the system in maintaining uninterrupted grid operation and adapting PV generation to the needs of the microgrid.
