Coordinated Operation of Wind-Solar-Hydrogen System Based on Nash Bargaining

Wind-Solar-Hydrogen energy system will become a key direction for the development of the future energy system. This study focuses on the coordinated operation of systems integrating wind, solar, and hydrogen. Firstly, a multi-agent optimal operation model considering direct electricity trading is constructed. Secondly, a collaborative operation framework is established based on Nash bargaining theory, which is decomposed into two optimization problems: maximizing the benefits of the wind-solar-hydrogen alliance and negotiating electricity trading payments. The Alternating Direction Method of Multipliers (ADMM) is used to solve these problems, achieving efficient solutions while protecting the privacy of each agent. Finally, the proposed cooperative mechanism is verified through simulation examples. The results show that it can significantly increase the benefits of each agent and the overall benefits of the alliance, demonstrating the effectiveness of the model in balancing individual and collective rationality.
