这项工作考虑了与空气源热泵运行相关的二氧化碳排放的潜在减少,这可以通过使用需求侧管理来实现。为了实现二氧化碳排放的大幅减少,人们普遍认为,供暖部门的电气化将需要与电力供应的脱碳相结合。通过影响电动热泵运行的时间,使其与边际碳排放系数较低的发电更吻合,有人建议可以进一步减少这些排放。为了研究这种可能性,基于2020年至2050年情景的英国电网模型与空气源热泵机组的动态模型和住宅人口的热模型相结合。对热泵的性能和与热泵相关的二氧化碳排放量进行了比较,包括有和没有需求侧管理干预,这些干预旨在在所产生的电力的边际排放系数较低时优先运行。研究发现,这些干预措施不太可能在实现进一步减排方面有效。在基于2035年左右的情景中,观察到的降幅约为3%,但在其他情景中,降幅微乎其微。在高风力发电量(2050年)的情况下,这里考虑的DSM方案倾向于改善热舒适性(排放量增加最小),而不是实现排放减少。讨论了产生这种现象的原因,并提出了进一步的建议。
This work considers the potential reduction in the carbon dioxide emissions associated with the operation of Air Source Heat Pump which could be achieved by using demand side management. In order to achieve significant reductions in carbon dioxide emissions, it is widely envisioned that electrification of the heating sector will need to be combined with decarbonisation of the electrical supply. By influencing the times at when electric heat pumps operate such that they coincide more with electricity generation which has a low marginal carbon emissions factor, it has been suggested that these emissions could be reduced further. In order to investigate this possibility, models of the UK electrical grid based on scenarios for 2020 to 2050 have been combined with a dynamic model of an air source heat pump unit and thermal models of a population of dwellings. The performance and carbon dioxide emissions associated with the heat pumps are compared both with and without demand side management interventions intended to give preference to operation when the marginal emissions factor of the electricity being generated is low. It is found that these interventions are unlikely to be effective at achieving further reductions in emissions. A reduction of around 3% was observed in scenarios based around 2035 but in other scenarios the reduction was insignificant. In the scenarios with high wind generation (2050), the DSM scheme considered here tends to improve thermal comfort (with minimal increases in emissions) rather than achieving a decrease in emissions. The reasons for this are discussed and further recommendations are made.
