The "double carbon" strategic goal has put forward higher requirements for the transformation and development of China’s energy structure,prompting the energy industry to develop towards clean,low-carbon,and high-quality.As a multi-energy integration platform,the integrated energy system can efficiently utilize clean energy,promote multi-energy synergistic supply and heterogeneous energy gradient utilization,improve energy utilization efficiency,and reduce carbon emission.As the smallest unit of the integrated energy system,the park integrated energy system takes the park as the carrier to supply and manage multiple energy sources,such as electricity,heat,and gas,to achieve efficient energy utilization and emission reduction,improve the safety,stability,and economy of urban energy supply,and help achieve the goal of "double carbon".It is important to strengthen the construction of integrated energy systems in parks for the transformation of energy structure and sustainable development in China.Therefore,The thesis mainly researches the multi-park integrated energy system with multi-energy interconnection,and the main contents are as follows.(1)The integrated energy system model of the park is studied.Firstly,the mathematical model of the important equipment of the integrated energy system of the park is established;secondly,the integrated energy system model based on energy hubs is introduced,and the integrated demand response mathematical model is established.(2)An economic optimal dispatch model of the integrated energy system of the park considering the stepped carbon trading mechanism is constructed.Firstly,a stepped carbon trading mechanism model is established.Then,the low-carbon economic optimal dispatching model of the integrated energy system of the park considering the carbon trading mechanism was established for the requirements of the operating cost of the integrated energy system of the park and the environmental protection of the system,to minimize the operating cost and carbon emission of the park,take into account the constraints of energy balance,stable operation of equipment and safe operation of the system network,and combined with the comprehensive demand response,and simulated to verify the example.(3)The optimal scheduling model of a multi-park integrated energy system considering the interests of users is established.First,the operation mode of the multi-park interconnected integrated energy system is analyzed,and the architecture and model of the multi-park integrated energy system are established.Then,considering the interests of multiple subjects in multi-park,a comprehensive demand response and user participation and compensation mechanism are established,and a multi-park integrated energy system optimal scheduling strategy based on the hybrid game mechanism is constructed.The grey wolf intelligent optimization algorithm combined with CPLEX is used to solve the scheduling model.Finally,the analysis proves that the proposed optimal scheduling strategy has certain advantages in enhancing the enthusiasm of users’ participation in demand response,taking into account the system economy,environmental protection,and the interests of different interests,and provides a reference for achieving stable and economic operation of the multi-campus integrated energy systems in the future.
