Distributed Power Distribution Management in AC Microgrids Using Game Theoretical Approach

Recent advancements in the modern grid and energy sector have pivoted the focus towards the optimal power allocation of large-scale distributed generator (DG) units, especially when user-generated power integrates with microgrids (MGs). This study employs the Cournot oligopoly game to ascertain the Nash equilibrium between the power generation company and the power generation user when the MG operates in an island mode. Through this Nash equilibrium, we determine the ideal proportion of power production between the company and the user. To maximize the benefits and maintain MG stability, we introduce a distributed control approach rooted in consensus theory. This methodology prompts each DG to adjust its power output in line with the collective consumption load. By leveraging the Nash equilibrium-derived optimal power generation ratio, we effectively eradicate the steady-state frequency deviation across all DG units within the MG, consequently upholding power quality standards for users. Simulation outcomes affirm the efficacy of our proposed control strategy in meeting the outlined research objectives.
