Low-carbon Optimal Scheduling of Regional Integrated Energy System Under Different Heating Modes

In recent years, with the ever-increasing contradiction between energy supply and environmental protection, how to reduce environmental pollution, improve energy efficiency, and establish a safe and efficient energy utilization model have become the focus of worldwide attention. Based on the concept of low-carbon economy, this paper introduces the carbon trading, and takes the minimum sum of total operating cost and carbon trading cost as the objective function to establish a low-carbon economic model of the regional integrated energy system (IES), which is composed of gas turbines, photovoltaic cells, storage batteries and other com-ponents. The problem of low-carbon optimal scheduling when heat pumps, electric boilers and gas boilers are used as auxiliary heating equipment respectively, is studied. A case study is performed to show the effectiveness of this model. Finally, the impact of the coefficient of performance (COP) of the heat pump on system economic benefits is analyzed.
