Holistic view of active distribution network and evolution of distribution automation

Active network management of distribution networks has been proposed to enhance the reliability of network and the hosting capacity for renewable energy sources. Traditional distribution automation solutions are not scalable enough to utilize large-scale distributed energy resources in network management. The concept of commercial and technical aggregator is therefore merged with the concept of active network management. The aim of this paper is to provide a holistic overview of active network management utilizing flexibility services from aggregator. Special emphasis is given to distribution automation and how these systems need to be evolved.
