The annual NEIS conference is hosted by the chair of Electrical Power Systems of the Helmut Schmidt University in Hamburg. Since 2013 it provides a forum for scientists and experts to discuss prospective and recent developments in the fields of energy supply and energy storage technologies. This year's conference continues to focus on electrical power grids and grid-related aspects, including load management, power system measurements and identification techniques, energy storage systems, and the integration of electric mobility into the grid.
