Mario Vašak (born on 13th August 1980 in Bjelovar, Croatia) is a full professor at the Department of Control and Computer Engineering, University of Zagreb Faculty of Electrical Engineering and Computing (FER) and he is heading its Laboratory for Renewable Energy Systems. His research interests are in the domain of dynamic systems predictive control with applications to systems from the low-carbon energy sector: wind turbines, energy-efficient buildings, microgrids, water distribution systems and electrified railway transport. He is the main inventor of the US patent for fault-tolerant control of wind turbine generators. He designed the concept of hierarchical and modular energy management in buildings with integrated microgrids for enabling their economically optimal interoperation. He had a leading or collaborator role on several research projects funded by the European Union or Croatian national funds related to implementation of this concept and its verification from the level of consumption control in individual buildings to the level of coordination of infrastructure and buildings in the smart city environment (ERDF ENHEMS-Buildings, HRZZ 3CON, FP7 UrbanWater, FP7 DYMASOS, ERDF FER-KIET). He is the coordinator of the 3Smart project (Smart Building – Smart Grid – Smart City) financed from ERDF through the Interreg Danube Transnational Programme. He is the author or co-author of more than 15 papers in international scientific journals and overall of more than 100 internationally reviewed papers. He served as president of Control Systems Chapter of the IEEE Croatia Section in period 2014-2017.
