Energy Management for Microgrids Using a Hierarchical Game-Machine Learning Algorithm

This paper presents an energy management strategy for microgrids using a multiagent game-learning algorithm. This microgrid is powered by photovoltaic (PV) systems equipped with batteries and is intended to be operating in islanded mode. The proposed energy management strategy is applied to wireless communication networks by addressing the tradeoff between the communication signal's quality of service (QoS) and energy availability. A two-layer algorithm combining multiagent-game and reinforcement learning (RL) is designed for base stations (BSs) in order to accomplish the goal mentioned above. The proposed method shows improvement in the microgrid's performance and has a higher converging speed compared to a direct RL approach. The designed energy management algorithm was tested in multiple case studies.
