An Interactive Operation Method of Integrated Energy Microgrids Based on Non-cooperative Game

With the advancement of microgrid technology, the coupling and energy flow between various microgrids have become increasingly intertwined. To better facilitate energy flow, the comprehensive energy trading market is progressively developing and expanding. Building on this, this paper proposes an interactive operation method based on Peer-to-Peer (P2P) transaction and non-cooperative game theory. Firstly, a microgrid P2P trading model is established with the objective of maximizing profits. Secondly, a P2P transaction pricing mechanism for microgrid groups is constructed using the supply-demand ratio (SDR). Subsequently, a non-cooperative game model is formulated based on the established model, and the existence and uniqueness of the Nash equilibrium are proven. Additionally, the Nikaido-Isoda function is introduced to improve computational accuracy while reducing computational complexity. Finally, simulation results validate the effectiveness of the proposed method.
