Evaluating decentralized P2P trading methods of local renewable energy for local consumption

Abstract

The liberalization of electricity buying and selling and regional decentralization have progressed with respect to the stable use of electricity, and the use of renewable energy is being promoted for global warming countermeasures. However, renewable energy has large fluctuations in output, depending on time and place, so the amount of power can be either too large or too small, preventing a stable regional power system from being formed. We propose new decentralized peer-to-peer (P2P) negotiation methods for optimizing the surplus and shortage of power within a region by sharing local renewable energy, and we evaluate the methods by multi-agent simulation.
