| 摘要: |
| 在将环境成本全部计入发电成本的基础上，构建跨省输电合同双方火电机组发电权交易模型，并以西电东送南通道的贵州和广东为例，计算环境成本对交易收益的影响；通过敏感性分析研究主要不确定性因素对交易收益的影响程度，并基于此确定交易的可行区域。结果表明：不计环境成本时，广东火电机组受外来电力影响的负荷可通过交易全部得到利用，交易双方均获得收益；计及环境成本之后，广东1 000 MW机组参与交易的收益增加，300 MW以下机组无法参与交易，所有机组的总交易收益降低；计及环境成本的单位煤耗成本及其省间差异分别是影响最大的正面因素和负面因素，可交易电量的降低量和输电损耗主要影响广东300 MW机组参与交易的收益，在这4个因素发生使收益降低的变动时，广东300 MW机组参与交易的可行性最先变化。 |

| Abstract: |
| A model of thermal power unit generation right trade between two parties of trans-province power transmission contract is built with the environmental cost as a part of generation cost and the impact of environmental cost on the trade profit is calculated for Guizhou and Guangdong in south channel for sending power from west to east China. The sensitivity analysis is adopted to analyze the impact of main uncertainty factors on the trade profit and determine the feasible trade areas. Results show that，without the environmental cost，all the thermal power units of Guangdong can operate through the generation right trade and both parties get profit；with the environmental cost，the trade profit of Guangdong 1 000 MW units increase while the total trade profit decrease because its units below 300 MW are out of the trade；with the environmental cost，four main factors influence the trade profit of Guangdong 300 MW units，including the unit coal price，its difference between provinces，the amount of tradable electricity reduction and the power transmission loss. When the variation of the four factors makes the trade profit decreasing，the trade feasibility of Guangdong 300 MW units is influenced first. |
