Dr. Ing. Sergio F. Contreras is currently a posdoctoral researcher at the IAT institute of the University of Bremen. His research interest comprises planning and management of hybrid active distribution networks and multi-energy systems based on computational intelligence techniques; multi-objective optimization, evolutionary computation, swarm intelligence, metaheuristic algorithms, multi-criteria decision making, uncertainty models and graph techniques. Durting his doctoral studies he proposed a probabilistic multi-objective microgrids planning (POMMP) methodology for the planning under uncertainties of microgrids with high penetration of distributed energy resources and the capacity of providing ancillary services to the main grid. Prior to his doctoral studies, he worked at Siemens in the electric motors manufacturing area as Junior design engineer. His professional experience was in the proposal and development of research projects about energy efficiency; the definition, implementation and planning of tests under international standards in electric motors; execution of projects in energy efficiency and product development.
