A Stackelberg Game Approach for Energy Sharing Management of a Microgrid Including Photovoltaic and Wind Turbine Prosumers

Abstract

In this paper, the problem of energy sharing management of a microgrid including photovoltaic and wind turbine prosumers is considered. To solve this problem, a single-leader multi-follower Stackelberg game approach is performed. In the given approach, as a centralized coordinator, microgrid operator (MGO) conducts energy sharing between the prosumers, and therefore, is taken as the leader. Due to the mission of the leader, the MGO determines internal buying and selling prices in each time slot. Thus, the prosumers, which behave as followers, adjust their consumption values based on the pricing policy of the MGO. Accordingly, the MGO aims to optimize the energy sharing in the microgrid with the maximization of its profit while all prosumers act in their interests. To achieve this purpose, an optimal pricing model is given. Also, a case study is presented to perform the game approach and show its effectiveness.
