Multi-agent Reinforcement Learning for Low-Carbon P2P Energy Trading among Self-Interested Microgrids
This addresses energy management and carbon reduction for self-interested microgrids, but it is incremental as it applies known methods to a specific domain.
The paper tackled the challenge of uncertain renewable generation and demand in microgrids by developing a multi-agent reinforcement learning framework for peer-to-peer energy trading, resulting in improved renewable utilization, reduced reliance on high-carbon electricity, and increased community-level economic welfare.
Uncertainties in renewable generation and demand dynamics challenge day-ahead scheduling. To enhance renewable penetration and maintain intra-day balance, we develop a multi-agent reinforcement learning framework for self-interested microgrids participating in peer-to-peer (P2P) electricity trading. Each microgrid independently bids both price and quantity while optimizing its own profit via storage arbitrage under time-varying main-grid prices. A market-clearing mechanism coordinating trades and promoting incentive compatibility is proposed. Simulation results show that the learned bidding policy improves renewable utilization and reduces reliance on high-carbon electricity, while increasing community-level economic welfare, delivering a win-win situation in emission reduction and local prosperity.
