电力部门的排放大大加剧了环境空气污染及其相关的对人类健康的不利影响。在这项研究中，我们探讨了如何经济有效地减少健康影响，由于细颗粒物（PM2.5）可归因于发电厂排放的内部化实时健康成本在工厂调度决策和重新优化机组的承诺和经济调度，根据这些影响。我们发现，将时间和位置变化的健康损害成本内化到电力系统运营决策中，可以通过减少煤炭发电量和污染物排放位置和时间的战略转变，减少61%-97%的不利健康影响。我们还发现，在电网中增加储能可以通过减少风电限电来减轻对健康的影响。我们的研究结果表明，在确定排放的社会成本时，需要考虑时间和空间的异质性。
Emissions from the power sector significantly contribute to ambient air pollution and its associated adverse human health impacts. In this study, we explore how to cost-effectively reduce health impacts due to fine particulate matter (PM2.5) attributable to power plant emissions by internalizing real-time health costs in plant dispatch decisions and re-optimizing the unit commitment and economic dispatch in light of these impacts. We show that internalizing the time- and location-varying health damage costs into power system operational decisions can reduce 61%-97% of adverse health impacts through decreases in coal generation and strategic shifts in the location and timing of pollutant releases. We also find that adding energy storage to the grid can mitigate health impacts by reducing wind power curtailment. Our findings demonstrate the need to consider temporal and spatial heterogeneity when determining the social cost of emissions.
