Smart distribution grid application with different storage elements

Abstract

On account of the profound change process in electric power generation, transmission and distribution a lot of activities are started to plan, to build up and to operate smart distribution grids. Experiences from laboratory test setups are well known, experiences from public used smart grids are actually published only a little. Therefore there are numerous questions how to adapt the smart grid characteristics to the special boundary conditions of a given grid region and which divergences must be considered between planning and operation. This paper describes some key experiences in planning, building up and operating a smart grid for the German isle of Pellworm. It takes into account the first lessons learned from the operation of this smart grid.
