A game model for multi-energy transaction in a gas-heat-power network-coupled system

With the development of multi-energy convertors, different systems are coupled with each other both in power flow and market behaviors. Analysis of multi-energy transaction patterns and market equilibrium is one of the heated topics. Game theory provides us a powerful tool to settle such problems. This paper proposes a game model for transaction in integrated multi-energy networks such as a gas-heat-power system. Detailed network modeling and individual interest of each system are included. A general structure of such problems is given and solution methodology is put forward to obtain the Nash equilibrium. Case studies demonstrate the effectiveness of the proposed model and the interplay between these three systems. Some prospects for future researches are also given.
