Jimmy Ehnberg

Forskare at Chalmers, Electrical Engineering, Electric Power Engineering

Jimmy Ehnberg got his MSc. Degree in electrical engineering at Lunds Institute of Technology at the University of Lund in 2001. He got Lic. eng. and Ph.D. degree from Chalmers in 2003 and 2007, respectively. Today he is working as project coordinator at Elteknik in Smart grids and his research interest are among others distribution grids and integration of renewables to the grid. He is also a co-founder of STEEP-RES that is a multidisciplinary research group focusing on renewable electricity production for autonomous grids in developing countries. Jimmy is director of the master's programme in Electric power engineering.
