The future organization of Danish electricity market for integrating DERs — A view of FlexPower project

This paper presents a view of the Danish FlexPower project to reform the existing electricity market by coordinating vast Distributed Energy Resources (DERs) for integration in future scenarios. Aiming to maximize the preservation of the existing market structure, Aggregator, the key player in mobilizing small-scale DERs to participate in the existing electricity market, is proposed in this paper to cope with the day-ahead, intra-day and regulating power market. Possible future organizations of different time-scale markets are also introduced and discussed with the precise roles and responsibilities of Aggregator. It is seen that the most appropriate function for Aggregator's capabilities is to cluster DERs as an expended ancillary service. In addition, the interactions with current market actors are introduced in detail.
