Infos

In this book an overall energy system optimization is performed in various contexts. The system takes respect of a grid connection and its load, a mechanical drive train system (mDTS). To achieve best performance of the mDTS, a battery system as part of a power link is included as energy storage. 

Philip Karl-Heinz Dost holds a graduate diploma from Ruhr University Bochum, he is the head of group of Energy Storage Systems within the Institute of Power Systems Technology and Power Mechatronics. He has been working in the field of energy systems with focus on energy storage systems and electromobility as well as power electronic devices.
