Neighbors' Personality Traits Impact in Residential Microgrid Units' Cooperation for Energy Sharing Based on a Complete Game Theoretic Approach

In this paper, a game-theoretic strategy is used to investigate residential units' cooperation on excess demand. Since household consumption during the weekdays is approximately consistent, retailers should buy energy from substations to supply the consumer demand and announce day-ahead market prices to them. conversely, if a unit needs excess demand, it must purchase it on the spot market at a higher price. Using social-technical cooperation of nearby neighbors, this study examines the allocated excess budget costs due to unscheduled excess demand. In this complete information game-theoretic social approach, every player has their own economic characteristics based on their level of cooperation and decision making. The proposed method is applied on residential test microgrid utilizing GAMS employing CPLEX solver. Based on simulation results, neighbors are able to cooperate and supply excess demand among themselves. Furthermore, the given approach reduces total cost by up to 25%.
