Applications of game theory in microgrids

Abstract

A microgrid, which can be defined as a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid, has been studied extensively in recent years. This paper will explore the application of non-cooperative game and cooperative game in microgrids. For an individual microgrid that is connected with renewable energy sources through DC-DC converters, a non-cooperative game theory based PI controller tuning method is proposed to help make more stable output voltage. For microgrids that are connected in network, a cooperative game theory based local energy exchange scheme is proposed to help them meet their energy requirements while achieving higher individual utility.
