UniGreen represents a group of researchers from various fields of expertise. The primary goal is to make a synergy between different departments at the Faculty of Electronic Engineering to improve scientific and research excellence in renewable energy sources and microgrids. The group has been expanded by joining colleagues from the Faculty of Sciences and Mathematics, who we believe can significantly contribute to the work of this group with their experience. Key R&D activities are in three focus areas: Photovoltaic technologies, Microgrids, and Smart grids integration.
