考虑碳排放权交易的短期节能调度

Short-Term Energy-Saving Schedule with Carbon Emission Trading Considered

针对如何降低火电系统CO2排放量问题,简要介绍了碳排放权交易的理论,提出在电力系统短期调度中引进碳排放权交易机制,以进行总量控制,逐渐减小CO2排放量。在电力市场条件下,分别以CO2排放最小、火电厂收益最大和电网购电费用最小为目标建立优化数学模型。采用水电调峰法对改进的IEEE14节点系统算例进行分析,验证所建立的模型的合理性。结果表明,目前在我国以火电为主系统中考虑碳排放权交易,可以降低火电的减排成本,有利于控制总体排放水平。

This paper deals with how to reduce CO2 emissions in the thermal power system. Firstly, it briefly introduces the carbon emissions trading mechanism, and proposes that the mechanism should be introduced in the short-term dispatching and control in the electric power system to control the total emission and reduce it gradually. Secondly, under the condition of electricity market, an optimized model is established with the minimum CO2 emission, maximum thermal power profit and minimal grid purchase cost respectively. Thirdly, the improved IEEE14 bus system is analyzed with peak shaving method to verify that the model is reasonable. The results suggest that taking carbon emission trading into consideration can reduce the cost of emission reduction in the thermal power plant and help to control the overall emission level.
