【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1000 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300MW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]:On the basis of taking environmental cost into account of generation cost, this paper constructs a power generation right trading model for power generation units of both sides in inter-provincial transmission contract, and takes Guizhou and Guangdong as examples to calculate the impact of environmental cost on transaction income. Based on the sensitivity analysis, the degree of influence of the main uncertainty factors on the trading returns is studied, and the feasible region of the transaction is determined. The results show that the loads of Guangdong thermal power generating units affected by external electricity can be fully utilized by trading without taking into account the environmental costs, and both sides of the transaction can benefit from the load, taking into account the environmental costs, Guangdong 1000 MW units to participate in the transaction income increase, less than 300MW units can not participate in the transaction, the total transaction income of all units reduced; Considering the environmental cost, the unit coal consumption cost and its inter-provincial difference are the most positive and negative factors, respectively. The reduction of tradable electricity and the transmission loss mainly affect the profit of Guangdong 300MW unit participating in the transaction. The feasibility of 300 MW units in Guangdong to participate in the transaction is the first to change when these four factors cause the decrease of income.
