Abstract
In this paper a concept of real-time reactive power control by electric vehicles is discussed. Electric vehicles pose potential issues for low-voltage distribution grids, such as violations of the minimum voltage boundary. Grid reinforcement can be prevented with innovative control concepts utilizing the existing power electronics in electric vehicles. The Fraunhofer Institute for Solar Energy Systems in Freiburg, Germany, developed and evaluated an on-board charging system featuring a four-quadrant charger and an on-board grid controller, the communication and control strategies. Simulation studies show significant effects in the low-voltage grid. The proof-of-principle was carried out in the lab, demonstrating the complete signal processing chain.
