To realize the goal of net zero energy building(NZEB),the integration of renewable energy and novel design of buildings is needed.The paths of energy demand reduction and additional energy supply with renewables are separated.In this study,those two are merged into one integration.The concept is based on the combination of photovoltaic,thermoelectric modules,energy storage and control algorithms.Five types of building envelope systems,namely PV+TE(S1),Grid+TE(S2),PV+Grid+TE(S3),PV+Battery+TE(S4)and PV+Grid+Battery+TE(S5)are studied,from aspects of energy,economic and environmental(E3)performance.The new envelope systems can achieve thermal load reduction while providing additional cooling/heating supply,which can promote advance of NZEBs.It is found that there is a typical optimum setting of thermal energy load for each one of them with minimum annual power consumption.Except for the S1 system,the rest can realize negative accumulated power consumption in a year-round operation,which means the thermal load of building envelope could be zero.The uniform annual cost for S1 to S5 under interest rate of 0.04 are 19.78,14.77,23.83,60.53,64.94$/m2,respectively.The S5 system has the highest environmental effect with 3.04 t/m2 reduction of CO_(2) over 30 years of operation.

Study on the Fine Configuration of Reservoir in River Facies Oilfield in Bohai Sea Area

引用

Open Journal of Applied Sciences 2024年第2期14卷 391-397页

作者： Jianmin zhang Xijie Wang Pengfei Mu shicong Lyu Jun Xie Bohai Oilfield Research Institute Tianjin Branch of CNOOC Ltd. Tianjin China

The geological conditions of offshore shallow water delta oil reservoirs were complex, with limited well data and large well spacing. Taking A Oilfield in the Bohai Sea Area, China as an example, the target sand body was formed in a shallow water delta sedimentary environment, with well-developed underwater distributary channels and frequent branching and diversion. The reservoir was strong non-uniformity and uneven plane water cut pressure. To this end, based on the existing work of predecessors, combined with seismic, logging, and production dynamics data, and based on the genesis mechanism of shallow water delta reservoirs, the boundary of composite river channels was identified through seismic facies, and logging facies were used to subdivide them into single river levels within the composite river channels. Then, seismic waveform characteristics were applied to track and characterize the plane distribution of single river channels, guiding the efficient development of offshore shallow water delta oil fields and achieving increased storage and production in Bohai Oilfield, China.

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。

传统螺栓连接件的直径小于钢梁预留孔的孔径,导致螺栓与孔壁存在间隙,容易引发钢梁与上部混凝土板间发生相对滑移使组合梁挠度增大。为尽量减小或消除上述间隙,本文引入铰制孔螺栓和螺纹孔螺栓作为组合结构的剪力连接件,并提出锥套自锁螺栓连接件。设计并开展了8个螺栓连接件推出试验,基于各试件的荷载-滑移曲线,研究了3种螺栓连接件与传统螺栓连接件间的抗剪承载力、滑移能力及抗剪刚度等受剪力学性能的具体差异。研究结果表明:3种螺栓连接件的破坏形态与传统螺栓连接件表现一致,均为螺栓杆剪断,混凝土无压溃现象;3种螺栓连接件的抗剪承载力均接近于传统螺栓连接件的抗剪承载力;基于试件的荷载-滑移曲线,3种螺栓连接件均可分为弹性阶段、塑性阶段及破坏阶段;3种螺栓连接件的延性系数和抗剪刚度均明显优于传统螺栓。综合考虑力学性能、施工性能和经济性,本文建议选用铰制孔螺栓用于组合结构的剪力连接件。

Photo-driven water splitting photoelectrochemical cells by tandem organic dye sensitized solar cells with I-/I3- as redox mediator

引用

Science China Chemistry 2020年第2期63卷 228-236页

作者： shicong zhang Haonan Ye Haoran Ding Fengtao Yu Jianli Hua Key Laboratory for Advanced Material Feringa Nobel Prize Scientist Joint Research Center and School of Chemistry and Molecular EngineeringEast China University of Science and Technology

Dye-sensitized photoelectrochemical tandem cells have shown the promise for light driven hydrogen production from water owing to the low cost,wide absorption spectra in the visible region and ease to process of their constitutive photoelectrode materials.However,most photo-driven water splitting photoelectrochemical cells driven by organic dye sensitized solar cells exhibit unsatisfactory hydrogen evolution rate,primarily attributed to their poor light capturing ability and low photocurrent performance.Here we present the construction of a tandem system consisting of an organic blue-colored S5 sensitizer-based dyesensitized photoelectrochemical cell(DSPEC) wired in series with three spectral-complemental dyes BTA-2,APP-3 and APP-1 sensitizers-based dye-sensitized solar cell(DSC),respectively.The two spectral-complemental chromophores were used in DSC and DSPEC to ensure that the full solar spectrum could be absorbed as much as possible.The results showed that the photocurrent of tandem device was closely related to the open-circuit voltage(Voc) of sensitized DSC,in which the tandem configuration consisting of S5 based DSPEC and BTA-2 based DSC gave the best photocurrent.On this basis,tandem device with the only light energy and no external applied electrical bias was further constructed of BTA-2 based 2-junction DSC and S5 based DSPEC and obtained a photocurrent of 500 μA cm-2 for hydrogen generation.Furthermore,I-/I3-was used as a redox couple between dye regeneration and O2 production on the surface of Pt-IrO2/WO3.The strategy opens up the application of pure organic dyes in DSC/DSPEC tandem device.

Effects of anchoring groups on perylenemonoimide-based sensitizers for p-type dye-sensitized solar cells and photoelectrochemical cells

引用

Journal of Energy Chemistry 2018年第3期27卷 728-735页

作者： Kang Yun shicong zhang Fengtao Yu Haonan Ye Jianli Hua Key Laboratory for Advanced Materials Institute of Fine Chemicals School of Chemistry and Molecular Engineering East China University of Science and Technology

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.

Spin-decoupled metasurface for simultaneous detection of spin and orbital angular momenta via momentum transformation

引用

Light(Science & Applications) 2021年第4期10卷 636-647页

作者： Yinghui Guo shicong zhang Mingbo Pu Qiong He Jinjin Jin Mingfeng Xu Yaxin zhang Ping Gao Xiangang Luo State Key Laboratory of Optical Technologies on Nano-Fabrication and Micro-Engineering Institute of Optics and ElectronicsChinese Academy of SciencesChengdu 610209China School of Optoelectronics University of Chinese Academy of SciencesBeijing 100049China

With inherent orthogonality,both the spin angular momentum(SAM)and orbital angular momentum(OAM)of photons have been utilized to expand the dimensions of quantum information,optical communications,and information processing,wherein simultaneous detection of SAMs and OAMs with a single element and a single-shot measurement is highly anticipated.Here,a single azimuthal-quadratic phase metasurface-based photonic momentum transformation(PMT)is illustrated and utilized for vortex recognition.Since different vortices are converted into focusing patterns with distinct azimuthal coordinates on a transverse plane through PMT,OAMs within a large mode space can be determined through a single-shot measurement.Moreover,spin-controlled dual-functional PMTs are proposed for simultaneous SAM and OAM sorting,which is implemented by a single spin-decoupled metasurface that merges both the geometric phase and dynamic phase.Interestingly,our proposed method can detect vectorial vortices with both phase and polarization singularities,as well as superimposed vortices with a certain interval step.Experimental results obtained at several wavelengths in the visible band exhibit good agreement with the numerical modeling.With the merits of ultracompact device size,simple optical configuration,and prominent vortex recognition ability,our approach may underpin the development of integrated and high-dimensional optical and quantum systems.
