Prosumers as Aggregators in the DEZENT Context of Regenerative Power Production

Abstract

Captive consumers of the current traditional and centralized power management systems will become proactive in the future of the smart grid. Their flexibilities will allow them to become prosumers. A prosumer (producer-consumer) is defined as a user that not only consumes electricity, but can also produce and store electricity. A new concept of aggregator has been introduced in the power market. The aggregator exploits the active participation of prosumers in order to provide commercial service in the power market. In this paper, we focus on power market models in which prosumers interact in a distributed environment during the purchase or sale of electric power. We propose a new aggregator which operates in the DEZENT power market model. The aggregator consists of a collection of prosumers who make use of reinforcement learning and of optimization techniques for the planning phase of their electricity production and consumption. In the paper we discuss the assumptions on which the aggregator design is based and we compare its behaviour with that of the aggregator proposed in the EU ADDRESS projects.
