Peer-to-Peer Energy Trading Framework for Microgrid Community Considering Community Hybrid Energy Storage

Peer-to-peer energy trading enhances intracommunity energy utilization and economic benefits in prosumer microgrids. This paper optimizes the operation of a microgrid community with profit-driven community hybrid energy storage using the Nash bargaining framework and dynamic bidding price-based peer-to-peer energy transactions. The decentralized, privacy-preserving optimization is validated on a microgrid community having three microgrids and a community hybrid energy storage system. Results show that dynamic bidding increases social welfare by <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\sim 18.16 \%$</tex> and self-consumption by <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\sim 27.31 \%$</tex> compared to the absence of peer-to-peer trading.
