Aggregation of Time-Dependent Flexibility in Cellular Organized Distribution Grids

Abstract

An increasing amount of flexibility providing entities are being installed in distribution grids supporting the development of active distribution networks. In distribution grids with cellular structure, aggregation of provided flexibility on cellular level enables the power exchange between energy cells without exchanging detailed information about each flexibility providing entity across energy cell boundaries. A multi-step optimization routine is developed to take account of the aggregation on energy cellular level based on cellwise power and energy limitations.
