Abstract

Abstract: Integrated energy system is an important way to achieve coordinated optimization between different energy systems. This paper firstly analyzes the four subsystems of electricity-heat-cool-gas, and constructs an economic optimization scheduling model for the park integrated energy system with the total cost as objective. Secondly, the non-linear method is used to transform the constructed scheduling model into a mixed integer programming problem. Finally, based on two scenarios of independent operation and coupled scheduling of subsystems, and combined with the time-of-use electricity price, the mixed integer programming software is used to solve the model. The result shows that, compared to the independent operation mode, the coupling scheduling mode can flexibly combine various energy conversion devices, greatly reducing the system's external energy purchase and the total system costs.

Key words: integrated energy system, electricity-heat-cool-gas subsystem, economic optimization scheduling, independent operation, coupled scheduling
