Optimization Study of Flexibility Scheduling Strategies for Independent and Interactive Operation of Regional Integrated Energy Systems

In today’s increasingly severe energy crisis, integrated energy systems have become an important way to solve the above problems because they can realize multi-energy complementarity and improve energy efficiency. The mathematical model of the integrated energy subsystem and the regional integrated energy system is constructed, and its objective function and constraints are analyzed, and then, based on the example, the data analysis of the operating costs of the multiple systems under the interactive operation mode and the independent operation mode is carried out. The results show that the system can save $6.61 \%$ of the total cost compared with the independent operation, which has better economic efficiency and energy utilization. By considering the changes in the costs of independent and interactive operation of the integrated district energy system at different confidence levels, it is concluded that the interactive operation mode is superior to the individual operation mode at any confidence level.
