Distributed coordination method of microgrid economic operation optimization based on multi-agent system

Microgrid economic dispatch is an important content of microgrid operation optimization, distributed control algorithm can be a good solution to solve microgrid economic dispatch problem. Replicator dynamics algorithm employed in the framework of a distributed multi-agent system (MAS)is presented in this paper. It divides a global optimization problem into multiple coordination optimization problems between agents to be solved. Each distributed generation in microgrid is controlled by an intelligence agent, and agents that in peer status imitate individual organisms interact with each other by the game algorithm to maximize their own benefits. When the game reach the nash equilibrium point, global optimal solution is obtained. The feasibility and effectiveness of the proposed distributed coordination method have been verified by a numerical test system.
