Carbon trading mechanism is an effective means to control greenhouse gas emissions. This paper focuses on the low-carbon economic operation of the integrated energy system under carbon trading mechanism in China. The integrated energy system includes the energy storage, ground source heat pump, and other equipment. The objective of this paper was to minimize the annual total cost of the system considering the carbon trading cost and study the operation modes under different carbon trading prices by commercial optimization software. The simulation results show the operation modes in summer are changed obviously with the increase of the carbon trading prices, while the operation modes in winter basically are not changed with the fluctuation of the carbon trading prices; under the carbon trading mechanism, the integrated energy system can not only reduce the carbon emissions, but also reduce the annual total cost through carbon trading, which shows its advantages and good development prospect. In addition, the setting of the carbon emission quota has a direct impact on the economy of the enterprises. Furthermore, the ground source heat pump and the electric refrigeration units can stabilize the fluctuation of the equipment output caused by the change of natural gas prices in this integrated energy system.

考虑碳交易机制的综合能源系统低碳经济运行

碳交易机制是控制温室气体排放的有效手段。本文着眼于碳交易机制下我国综合能源系统的低碳经济运行。综合能源系统包括储能、地源热泵等设备。本文的目的是在考虑碳交易成本的情况下最小化系统的年度总成本，并通过商业优化软件研究不同碳交易价格下的运行模式。仿真结果表明，夏季运行方式随着碳交易价格的上涨而发生明显变化，而冬季运行方式基本不随碳交易价格的波动而变化；在碳交易机制下，综合能源系统不仅可以减少碳排放，还可以通过碳交易降低年度总成本，显示出其优势和良好的发展前景。此外，碳排放配额的设定直接影响到企业的经济。此外，地源热泵和电制冷机组可以稳定这个综合能源系统中天然气价格变化引起的设备输出波动。
