针对建筑能源消耗过高问题,文章在独栋建筑中构建了带有热泵和热能储存的混合光伏/热能耦合系统,将其与需求侧管理概念相结合,开发了一个动态模拟模型描述其运行性能,进而对需求侧管理进行配置优化,分析了不同配置下的成本和能源使用情况。结果表明,需求侧管理下耦合系统上网电量占总发电量比率相比无储能系统在供暖、供冷季白天分别提升了23.96%,7.07%,索取电量在夜间大幅提升,总体增加了5.07%,104.50%,系统电力负荷调控能力良好,水箱温度设定点在供暖季及供冷季分别为43,24℃,是所有优化配置中总能耗最低的,比没有PVT和水箱的系统,年能耗降低41.77%,比不实施管理策略的节能率提高了7.10%。储能期消耗的电量在供暖、供冷季约占总耗电量的50.9%,72.7%。需求侧管理配置优化能够进一步降低系统能耗,特别是那些具备节能优势的系统,这对节能降耗具有良好的现实意义。

针对现有微电网规划评价方法在评价过程中未能充分考虑系统与环境中不确定因素对于评价结果影响的问题,提出一种基于后悔理论-多准则妥协解排序法(VIKOR)的微电网规划评价方法。首先,考虑微电网规划阶段的需求,构建了包含系统经济性、环保性与技术性等在内的微电网规划评价指标体系;而后,顾及专家主观经验与指标客观数据所包含的信息,采用层次分析法(AHP)-相关性定权法(CRITIC)对指标体系进行主客观组合赋权;最后,考虑不确定因素对评价结果的影响,基于后悔理论在评价过程中引入欣喜-后悔函数与状态变量对VIKOR法进行改进,建立了基于后悔理论-VIKOR法的微电网规划评价模型。算例分析表明,所提评价方法考虑系统与环境中不确定因素以及决策者心理预期对于规划方案评价结果的影响,贴近于实际的微电网的规划方案决策需求。

Despite the large emission of chlorinated volatile organic compounds(CVOCs)into the atmosphere,the ultimate fate of these compounds remains largely ***,we explore the photochemical conversion of an important class of CVOCs,namely chlorobenzene(CB),on mineralα-Fe_(2)O_(3)particulates under atmospheric relevant conditions.A series of chamber reactions composed of the CB with/without SO_(2)or NO_(2)are performed,followed by in situ diffuse reflectance infrared Fourier transform spectroscopy measurements and density functional theory *** show that CB can be considerably degraded byα-Fe_(2)O_(3)under light irradiation,whereas the reaction is markedly suppressed by adding SO_(2)or NO_(2)owing to their competitive adsorption and surface *** particular,we discover that CB can be ultimately converted into polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs)under dark state or light irradiation,suggesting a possible origin of atmospheric PCDD/Fs from this overlooked photochemical source.
