Leader-Follower Game Optimization for Multi-Microgrid Integration in Distribution Networks

To address the multi-agent economic operation problem of a distribution network with multiple microgrids, a leader-follower game optimization model is proposed. In this model, the distribution system operator (DSO) serves as the leader, aiming to maximize its profit by setting transaction prices for microgrids (MGs). The MGs, as followers, optimize their operational strategies to minimize costs based on the given transaction prices. By integrating the DSO's pricing strategy with the MGs' power purchase and sale plans within the distribution network, the model fosters a mutually beneficial outcome for all stakeholders. Simulation results, conducted on an IEEE 33-bus system with multiple microgrids, demonstrate the effectiveness and practicality of the proposed approach.
