HVAC/HVDC Grids

The development of electrical systems involves the integration of large volumes of renewable energy and regional interconnection between countries and continents. The growth of interconnected electrical systems has highlighted the need to develop SuperGrids, which require advanced techniques for power system analysis integrating HVDC Grids. This line of research integrates the study of techniques, models, and tools for expansion planning and operational planning, considering probabilistic aspects associated with renewable energy sources and the operation of system components.
