A FAST NASH EQUILIBRIUM CALCULATION METHOD IN AN ELECTRICITY RETAIL MARKET WITHIN A MICRO-GRID USING MULTI-AGENT SYSTEM

摘要

This paper proposes a method aiming at searching for the optimal Nash Equilibrium (NE) using Multi-Agent System in an electricity retail market with perfect static gaming within a micro-grid (MG). This method is designed distributedly and is capable of doing directional search to acquire a better calculation speed. Results show that this method is effective in finding optimal NE with lower electricity retail price. It takes advantage of competition, when number of players in the gaming increases, competition gets fiercer, the retail price decreases while the retail quantity increases, this is attractive to consumers and promotes the development of market environment. The proposed method calculates fast and satisfies the need of a real operation. Its scalability into a large MG is also good.
