摘要

目前基于系统排污总量控制方式制定的燃煤机组发电计划，缺乏针对性地缓解人口密集区域空气污染强度的调控机制。为此，在传统机组组合问题基础上，追加考虑污染物时空扩散特性的差别化环境容量裕度约束，通过限制对人口密集区域有较大影响的燃煤机组出力，来降低其排污量，进而改善相关区域空气质量，减小对人口健康的负面影响。其中，燃煤机组对人口密集区域污染物浓度贡献值的建模参照高斯烟团扩散模型、气象预报和重点地区污染等级预测信息进行。以混合整数规划形式建立了考虑环境容量裕度的机组组合模型，并对其进行了仿真分析。算例表明，差别化的环境容量裕度约束，能够在不引起系统经济和空气质量指数明显劣化的条件下，对人口密集区域空气污染强度实施更有针对性的调控，降低燃煤机组对人口健康的影响。

Abstract

At present

the generation schedule of coal-fired units based on the total air pollution of the whole system lacks the targeted regulation mechanism for mitigating air pollution concentration for densely populated areas. Thus

the differentiated environmental capacity constraints based on temporal and spatial dispersion characteristics of air pollutants are added to the conventional security-constrained unit commitment model. By curtailing the generation of coal-fired units that have severe impacts on air pollution concentration of densely populated areas to decrease the discharge capacity

the ambient air quality in these areas is improved and the health impact to human is decreased. In this model

the contribution from coal-fired units to the air pollutant concentration of densely populated areas is based on Gaussian puff dispersion model

forecasting meteorological information and forecasting pollution levels for key urban areas. The proposed model is formulated as a mixed integer programming problem and is simulated on a test system. The simulation results show that the proposed model with differentiated environmental capacity constraints can mitigate the health impact to human by the targeted regulation to the air pollution intensity in densely populated areas

without causing the noticeable degradation of system economy and air quality index.
