摘要
随着生态国内生产总值(ecologicalgrossdomestic product,Eco-GDP)核算体系的提出,燃煤机组减排带来的生态效益受到关注。为此,该文在发电收益目标函数中加入环保税和空气质量指数(air quality index,AQI)生态补偿金,提出能够驱动机组更为精细化减排的差别化燃煤机组安全约束组合(security-constrained unit commitment,SCUC)模型。该模型以环保税代替传统排污费,将燃煤机组排放的多项大气污染物纳入征税范畴;建立差别化AQI补偿金模型核算因发电计划调整、空气质量改善带来的生态效益。首先,利用高斯烟团扩散模型计算燃煤机组大气污染物排放对人口聚集区域大气污染物浓度的贡献额,即建立两者的源–受体映射关系;其次,考虑区域人口数量和AQI等级差别化因素整定补偿金调整系数;最后,以发电收入、发电成本、环保税和补偿金为优化目标,建立了Eco-GDP核算体系下的SCUC混合整数规划模型。算例表明,模型在定量评估燃煤机组计划调整对重点人居环境空气质量改善程度及由其带来的生态效益方面,具有合理性和可行性。
Under ecological gross domestic product(Eco-GDP) accounting system, the ecological benefits of emission reduction of coal-fired generation arouse worldwide concerns. This paper proposed a security-constrained unit commitment(SCUC) model for differentiated coal-fired units incorporating environmental protection tax and air quality index(AQI) ecological compensation. In the proposed model, the ecological damage of multiple air pollutants was calculated using tax instead of traditional pollution fee, and the AQI compensation model quantified the ecological benefit of power generation re-scheduling. Firstly, a Gaussian puff air dispersion model calculated the variation of regional air pollutant concentration caused by coal-fired units, namely it mapped regional air pollutant concentrations in response to the changes of generation scheduling. Secondly, the compensation was calculated considering differentiated regional population and AQI adjustment coefficients. Finally, integrating generation income, cost, tax and compensation, the SCUC model under Eco-GDP accounting system was formulated as a mixedinteger programming problem. Case studies demonstrate the validity and usefulness of the proposed model in improving air quality at densely populated regions.
