EI2460 Batteries for Energy Storage in Electrical Systems 6.0 credits

Batteries in electrical systems provide new possibilities for balancing and operating the electrical system, and can be seen as a new component in the electrical system. This course aims to provide an understanding of these possibilities, as well as to provide knowledge about mathematical methods in order to model and analyze the impact on the electrical system.
