摘要：
An analytical model of multi-leader multi-follower Stackelberg game between the distributed energy stations (DES) and the end users (EU) is proposed in order to explore the interactions between the two parties. The hierarchical Stackelberg game model considers the benefits of both DES and EU, and enables EU to make demand responses to maximize their welfare. In this model, the DES lead the game by independently deciding the amount of natural gas input for generation of both the electricity and heating energies and jointly setting the energy prices to maximize their own profit. While the EU, play as followers and determine the energy demands based on the prices the DES announced. The results show that the leaders game follows a supermodular game, which finally reaches a unique Nash equilibrium (NE). Moreover, the closed-form expression of the Stachkelberg equilibrium (SE) of the game between DES and EU is derived. The exsistence and uniqueness of the SE are also proved. Furthermore, a distributed algorithm is proposed to obtain the SE of this game with limited information. Numerical studies demonstrate the validity of the proposed game scheme as well as the efficiency of the distributed algorithm. © 2018 Automation of Electric Power Systems Press.
