Comparison of planning alternatives for active distribution networks

Abstract

A key element on the development of the future active distribution networks is to provide the network with storage devices, in order to compensate possible negative effects brought by a large integration of unpredictable generation. Software tools to aid Distributors to correctly assess the effectiveness of the use of storage as an alternative to traditional planning solutions (e.g. upgrading of the distribution lines) can be useful to planner engineers. The tool developed by the authors assists the DSO in defining the best integration strategies of distributed storage systems in distribution networks and in assessing their potential as an option for a more efficient operation and expansion of future electricity distribution networks. Examples derived by a representative distribution network are presented. (4 pages)
