Low-carbon Economic Dispatch Of Multi-region Electricity-gas Integrated Energy System Based On Cooperative Game

With the continuous development of society and economy,the increasingly serious greenhouse effect has brought a series of environmental problems.For this reason,my country has released the "two-carbon strategy" target to meet the challenges.In this context,the introduction of carbon capture systems in the integrated energy system has played a positive role in the operation of a low-carbon economy.However,in the face of the relationship between complex energy mutual conversion and economic benefits between multiple regional integrated energy systems,how to achieve low-carbon Maximizing the carbon economy is important.Therefore,based on the cooperative game,this paper introduces a multi-regional electricity-gas integrated energy system,constructs a regional low-carbon optimal operation model considering carbon capture and demand response,and proposes a multi-regional low-carbon optimal operation method based on cooperative game.First,the basic framework of the electricity-gas integrated energy system considering the carbon capture system is studied,and how the electricity-gas integrated energy system can realize the mutual conversion and complementarity of energy is analyzed as a whole.In order to construct a regional electricity-gas integrated energy system,a model of the internal carbon capture system,electricity-to-gas equipment,photovoltaic power generation,and electricity and gas energy storage equipment was established in the lowcarbon system.Secondly,aiming at the optimization of low-carbon economy of electric-gas integrated energy system,a low-carbon economy operation model of electric-gas integrated energy system considering carbon capture system and demand response is established.And the niche particle swarm algorithm is used to solve the model,which improves the convergence speed of complex models and avoids falling into the local optimal solution.By setting the electricity and gas loads and power outputs solved in different scenarios,the advantages of demand response,the coupling effect of electricity-to-gas equipment on the network,and the carbon capture equipment for low-carbon economic operation of the integrated energy system model are compared and analyzed.The simulation shows that the low-carbon optimization model of electric-gas integrated energy system considering carbon capture and demand response improves the economy and environmental protection of the system.Finally,aiming at the problem of coordinated low-carbon economy optimization of multiple regional electric-gas integrated energy systems,a low-carbon economic model of multi-regional electric-gas integrated energy systems based on cooperative game is established,and the distributed ADMM algorithm is used to solve the model,improving the The model solution speed is improved and the private information inside the integrated energy system is protected.The simulation results show that the integrated energy system maximizes the collective interests after the cooperative game,and distributes the interests reasonably through asymmetric Nash bargaining,so that each participating system will not suffer losses,and the enthusiasm of the system to actively participate in the cooperative game is improved.
