在实现零碳建筑的路径中引入市场化交易机制,对提高建筑业主建设零碳建筑积极性、促进全社会减排目标具有重要作用。本文分析了国内外零碳建筑引入市场化交易机制方式及发展现状,综合考虑了市场化交易机制的可行性与额外性,建议优先采用绿色电力交易与以CCER为主的碳信用产品交易,并针对我国零碳建筑引入市场化交易机制后存在的潜在技术问题进行讨论,以将近零碳建筑提升至零碳建筑为目标,提出了1种基于长期零碳排放锁定的成本效益法,确定了技术降碳与市场化交易机制综合应用时的约束方式,量化了零碳建筑引入市场化交易机制对碳交易市场的影响。结果表明:当市场化交易减排时间不低于10 a时,零碳建筑可同时兼顾环境效益与成本效益;当市场化交易减排比例不超过30%时零碳建筑成本效益最优;在此减排时间和比例下,积极推广零碳建筑参与碳交易市场,每年将带来150万t碳信用产品成交量,占自愿核证碳减排量市场成交量的10%~20%;综合考虑建筑自身资源、可行性与零碳建筑环境与成本效益,建议约束建筑设计阶段预购买交易产品的市场化交易减排时间不低于10 a。

针对微网独立运行时面临运行成本高,受可再生能源出力和多能负荷功率不确定性影响大等问题,提出一种基于混合两阶段鲁棒优化的多微网合作运行方法。首先,为了应对源荷双重不确定性挑战,在传统两阶段鲁棒优化基础上,提出一种基于多场景数据的最恶劣概率场景驱动的混合两阶段鲁棒优化方法,并采用可并行计算列与约束生成(column and constraint generation,C&CG)算法来提高求解效率。然后,在建立的多微网点对点分布式能源交易系统框架上,根据纳什谈判理论构造多微网合作成本最小化问题和收益分配问题,并提出一种耦合可并行计算C&CG的交替方向乘子法进行求解。最后,根据各微网不同的贡献率,设计一种基于点对点电能交易贡献度的非对称纳什谈判机制来分配各微网的合作收益。算例结果表明,所提方法能兼顾系统的鲁棒性、经济性和隐私性,并实现每个微网公平合理的收益分配。

In this work, two new dyes YK-1 and YK-2 with carboxylic acid and hydroxamic acid as anchoring groups,respectively, in combination with diphenylamine as donor and perylenemonoimide as acceptor were synthesized and applied in p-type dye-sensitized solar cells（p-DSCs） and dye-sensitized photoelectrochemical cells（PEC）. The results showed that the sensitizer（YK-1） based on carboxylic acid displayed a higher conversion efficiency of 0.064% under AM 1.5 solar conditions in p-DSCs. However, it was interesting that the hydroxamic acid based sensitizer（YK-2） on Ni O photocathode displayed better performance in a hydrophilic environment over a broad p H range under visible-light irradiation because of a versatile covalent attachment to Ni O surfaces. This may be ascribed to hydroxamic acid anchors, which have more sites interacting with the surface of Ni O in aqueous solution. This study demonstrates that YK-2 containing hydroxamic acid anchoring group is a promising candidate to achieve highly efficient and stable activity for dye-sensitized PEC system.
