An Efficient Peer-to-Peer Based Blokchain Approach for Prosumers Energy Trading in Microgrids

The pressure of climate change and the need to adopt renewable energy sources (RES) have led to an increased development of microgrid technologies. Their modularizable and scalable nature presents opportunities for the development of a new class of players in the power system, i.e. prosumers. The large-scale integration of RES creates acute challenges to the existing power systems. In this context, a reliable and secured balance between energy generation and consumption is highly required. To overcome these problems at microgrid level, a key role is played by the peer-to-peer energy trading using the blockchain concept. In this paper, we present an efficient approach that can be useful for energy trading using blockchain from both active participants (prosumers and consumers). The proposed approach meets the new Romanian regulation regarding prosumers. The results of the study emphasize that the proposed methodology could lead to an efficient balance between local supply and demand with benefits to the participants.
