1Photovoltaic and Solar Power Forecasting for Smart Grid Energy Management显示文摘Due to the challenge of climate and energy crisis,renewable energy generation including solar generation has experienced significant growth.Increasingly high penetration level of photovoltaic(PV)generation arises in smart grid.Solar power is intermittent and variable,as the solar source at the ground level is highly dependent on cloud cover variability,atmospheric aerosol levels,and other atmosphere parameters.The inherent variability of large-scale solar generation introduces significant challenges to smart grid energy management.Accurate forecasting of solar power/irradiance is critical to secure economic operation of the smart grid.This paper provides a comprehensive review of the theoretical forecasting methodologies for both solar resource and PV power.Applications of solar forecasting in energy management of smart grid are also investigated in detail.Can Wan Jian Zhao Yonghua Song Zhao Xu Jin Lin Zechun Hu 2015CSEE Journal of Power and Energy Systems2015,1,4:29
2Situation Awareness of Active Distribution Network:Roadmap,Technologies,and Bottlenecks显示文摘With the rapid development of local generation and demand response,the active distribution network(ADN),which aggregates and manages miscellaneous distributed resources,has moved from theory to practice.Secure and optimal operations now require an advanced situation awareness(SA)system so that operators are aware of operation states and potential risks.Current solutions in distribution supervisory control and data acquisition(DSCADA)as well as the distribution automation system(DAS)generally are not able to meet the technology requirements of SA.In this paper,the authors’participation in the project of developing an SA system as the basic component of a practical active distribution management system(ADMS)deployed in Beijing,China,is presented.This paper reviews the ADN’s development roadmap by illustrating the changes that are made in elements,topology,structure,and control scheme.Taking into consideration these hardware changes,a systematic framework is proposed for the main components and the functional hierarchy of an SA system for the ADN.The SA system’s implementation bottlenecks are also presented,including,but not limited to issues in big data platform,distribution forecasting,and security evaluation.Potential technology solutions are also provided.Jin Lin Can Wan Yonghua Song Renle Huang Xiaoshuang Chen Wanfang Guo Yi Zong You Shi 2016CSEE Journal of Power and Energy Systems2016,2,3:13
3Distributed Photovoltaic Generation in the Electricity Market:Status,Mode and Strategy显示文摘With the increasingly serious climate change and energy crisis,photovoltaic(PV)generation,as one of the most important renewable energy resources,has experienced dramatic growth worldwide due to its environmental friendliness.How-ever,the uncertainty and intermittency of PV bring inevitable challenges to power systems.With the rapid development of distributed PV and the continuous evolution of the electricity market,increasingly high penetration levels of distributed PV generation have led to a series of problems in power system operations,such as voltage fluctuation,frequency deviation,etc.The market participation of distributed PV needs to be solved.Reasonable market participation form,market mechanism and bidding strategies are vital to the development of distributed PV in the electricity market.This paper comprehensively reviews the development and impacts of distributed PV in the electricity market and discusses the relevant market modes and bidding strategies in detail.Sifan Jiang Can Wan Chen Chen Erbao Cao Yonghua Song 2018CSEE Journal of Power and Energy Systems2018,4,3:7

5A review on applications of heuristic optimization algorithms for optimal power flow in modern power systems显示文摘Optimal power flow(OPF)is one of the key tools for optimal operation and planning of modern power systems.Due to the high complexity with continuous and discrete control variables,modern heuristic optimization algorithms(HOAs)have been widely employed for the solution of OPF.This paper provides an overview of the latest applications of advanced HOAs in OPF problems.The most frequently applied HOAs for solving the OPF problem in recent years are covered and briefly introduced,including genetic algorithm(GA),differential evolution(DE),particle swarm optimization(PSO),and evolutionary programming(EP),etc.Ming NIU Can WAN Zhao XU 2014Journal of Modern Power Systems and Clean Energy2014,2,4:6
6A new Multilocus Sequence Analysis Scheme for Mycobacterium tuberculosis显示文摘Objective Tuberculosis remains one of the most serious infectious diseases in the world. In this study, a scheme of Mycobacterium tuberculosis (M. tuberculosis) multilocus sequence analysis (MLSA) was established for the phylogenetic and epidemiology analysis. Methods To establish the scheme of M. tuberculosis MLSA, the genome of H37Rv, CCDC5079 and CCDC5180 were compared, and some variable genes were chosen to be the MLSA typing scheme. 44 M. tuberculosis clinical isolates were typed by MLSA, IS6110-RFLP, and soligotyping, to evaluate the MLSA methods. Results After comparison of the genome, seven high discrimination gene loci (recX, rpsL, rmlC, rpmG1, mprA, gcvH, ideR) were chosen to be the MLSA typing scheme finally. 11 variable SNP sites of those seven genes were found among the 44 M. tuberculosis isolate strains and 11 sequence types (STs) were identified. Based on the Hunter-Gaston Index (HGI), MLSA typing was not as good for discrimination at the strain level as IS6110-RFLP, but the HGI was much better than that of spoligotyping. In addition, the MEGA analysis result of MLSA data was similar to spoligotyping/PGG lineage, showing a strong phylogenetic signal in the modern strains of M. tuberculosis. The MLSA data analysis by eBURST revealed that 4 sequence types (ST) came into a main cluster, showing the major clonal complexes in those 44 strains. Conclusion MLSA genotyping not only can be used for molecular typing, but also is an ideal method for the phylogenetic analysis for M. tuberculosis.LU Bing DONG Hai Yan ZHAO Xiu Qin LIU Zhi Guang LIU Hai Can ZHANG Yuan Yuan JIANG Yi WAN Kang Lin 2012Biomedical and Environmental Sciences2012,25,6:4
7Electric Load Clustering in Smart Grid:Methodologies,Applications,and Future Trends显示文摘With the increasingly widespread of advanced metering infrastructure,electric load clustering is becoming more essential for its great potential in analytics of consumers’energy consumption patterns and preference through data mining.Moreover,a variety of electric load clustering techniques have been put into practice to obtain the distribution of load data,observe the characteristics of load clusters,and classify the components of the total load.This can give rise to the development of related techniques and research in the smart grid,such as demand-side response.This paper summarizes the basic concepts and the general process in electric load clustering.Several similarity measurements and five major categories in electric load clustering are then comprehensively summarized along with their advantages and disadvantages.Afterwards,eight indices widely used to evaluate the validity of electric load clustering are described.Finally,vital applications are discussed thoroughly along with future trends including the tariff design,anomaly detection,load forecasting,data security and big data,etc.Caomingzhe Si Shenglan Xu Can Wan Dawei Chen Wenkang Cui Junhua Zhao 2021Journal of Modern Power Systems and Clean Energy2021,9,2:4
8Immunological Evaluation of a Novel Mycobacterium tuberculosis Antigen Rv0674显示文摘Objective This study aimed to characterize the diagnostic and vaccine potential of a novel Mycobacterium tuberculosisantigen Rv0674. Methods To evaluate thediagnostic potential and antigenicity of Rv0674, IgG was evaluated using ELISA and interferon (IFN)-γ was done by using ELISpot assay among TB patients and healthy donors. For immunogenicity evaluation, BALB/c mice were immunized with Rv0674. Cytokine production was determined by cytokine release assay using an ELISA kit, and the antibodies were tested using ELISA. Results The results of serum Elisa tests showed that Rv0674 specific immunoglobulin G (IgG) response was higher in TB patients than negative controls. And Rv0674 had good performance in serological test with sensitivity and specificity of 77.1% and 81.1%, respectively. While it shows poor sensitivity and specificity of 26.23% and 79.69% for IFN-γ tests. In BALB/c mice, Rv0674 adjuvant by DDA/PolyI:C could also induce a high level of IFN-γ, interleukin-2 and interleukin-6 as well as a high IgG titer in both high-and low-dose groups indicating that Rv0674 is essential in humoral and cellular immunity. Moreover, the cytokine profile and IgG isotypecharacterized Rv0674 as a Th1/Th2-mixed-type protective immunity with the predominance of Th1 cytokines. Conclusion Rv0674 may be a good potential candidate for the development of TB serological diagnosis and a new TB vaccine.XIAO Tong Yang LIU Hai Can LI Xiao Qin HUANG Ming Xiang LI Gui Lian LI Na YAN Yu Han LUO Qiao WANG Xue Zhi LI Ma Chao WAN Kang Lin 2019Biomedical and Environmental Sciences2019,32,6:3
9Preliminary Study on Drug Susceptibility Profile and Resistance Mechanisms to Macrolides of Clinical Isolates of Non-tuberculous Mycobacteria from China显示文摘Objective Macrolide susceptibility and drug resistance mechanisms of clinical non-tuberculous mycobacteria(NTM) isolates were preliminarily investigated for more accurate diagnosis and treatment of the infection in China. Methods Four macrolides, including clarithromycin(CLAR), azithromycin(AZM), roxithromycin(ROX), and erythromycin(ERY), were used to test the drug susceptibility of 310 clinical NTM isolates from six provinces of China with the broth microdilution method. Two resistance mechanisms, 23 S r RNA and erm, were analyzed with nucleotide sequence analysis. Results Varied effectiveness of macrolides and species-specific resistance patterns were observed. Most Mycobacterium abscessus subsp. massiliense were susceptible and all M. fortuitum were highly resistant to macrolides. All the drugs, except for erythromycin, exhibited excellent activities against slow-growing mycobacteria, and drug resistance rates were below 22.2%. Only four highly resistant strains harbored 2,058/2,059 substitutions on rrl and none of other mutations were related to macrolide resistance. G2191 A and T2221 C on rrl were specific for the M. abscessus complex(MABC). Seven sites, G2140 A, G2210 C, C2217 G, T2238 C, T2322 C, T2404 C, and A2406 G, were specifically carried by M. avium and M. intracellulare. Three sites, A2192 G, T2358 G, and A2636 G, were observed only in M. fortuitum and one site G2152 A was specific for M. gordonae. The genes erm(39) and erm(41) were detected in M. fortuitum and M. abscessus and inducible resistance was observed in relevant sequevar. Conclusion The susceptibility profile of macrolides against NTM was demonstrated. The well-known macrolide resistance mechanisms, 23 S r RNA and erm, failed to account for all resistant NTM isolates, and further studies are warranted to investigate macrolide resistance mechanisms in various NTM species.LI Fu LI Gui Lian PANG Hui LIU Hai Can XIAO Tong Yang LI Shuang Jun LUO Qiao JIANG Yi WANG Rui Bai WAN Kang Lin 2018Biomedical and Environmental Sciences2018,31,4:3
10Correlation between serum miR-154-5p and urinary albumin excretion rates in patients with type 2 diabetes mellitus:a cross-sectional cohort study显示文摘This study aimed to investigate the correlation between serum miR-154-5p and urinary albumin to creatinine ratio(UACR)in patients with type 2 diabetes mellitus(T2DM)and the association with biomarkers of inflammation and fibrosis in diabetic kidney disease(DKD).A total of 390 patients with T2DM were divided into three groups:normal albuminuria(UACR<30 mg/g,n=136,NA),microalbuminuria(UACR at 30-300 mg/g,n=132,MA),and clinical albuminuria(UACR>300 mg/g,n=122,CA).Circulating miR-154-5p,inflammatory(C-reactive protein(CRP);erythrocyte sedimentation rate(ESR);and tumor necrosis factor-a(TNF-α)and fibrotic markers(vascular endothelial growth factor(VEGF);transforming growth factor-β1(TGF-β1);and fibronectin(FN),and other biochemical indicators were assessed via real-time PCR,enzyme-linked immunosorbent assay,and chemiluminescence assay in patients with T2DM and 138 control subjects(NC).UACR,miR-154-5p,glycated hemoglobin(HbA1c),serum creatinine(sCr),blood urea nitrogen(BUN),ESR,CRP,VEGF,TNF-α,TGF-β1,and FN were significantly higher and the estimated glomerular filtration rate(eGFR)was significantly lower in NA,MA,and CA groups than in NC subjects(P<0.05).Elevated levels of UACR and miR-154-5p were directly correlated with HbA1c,sCr,BUN,ESR,CRP,VEGF,TNF-α,TGF-β1,and FN and negatively correlated with eGFR(P<0.05).miR-154-5p,HbA1c,sCr,BUN,eGFR,ESR,CRP,VEGF,TNF-α,TGF-β1,and FN were important factors affecting UACR.These findings indicated that elevated serum miR-154-5p is significantly correlated with high UACR in patients with T2DM and may offer a novel reference for the early diagnosis of DKD.Huiwen Ren Can Wu Ying Shao Shuang Liu Yang Zhou Qiuyue Wan 2020Frontiers of Medicine2020,14,5:2
11First Report in China on the Identification and Drug Sensitivity of Mycobacterium elephantis Isolated from the Milk of a Cow with Mastitis显示文摘Objective In this study, milk from a cow with mastitis was analyzed to determine the presence of mycobacterial infection. Milk quality and security problems pertaining to the safe consumption of dairy products were also discussed in this study. Methods Milk was preprocessed with 4% Na OH. Then, mycobacteria were isolated from the milk sample on L-J medium. The isolate was identified using multiple loci Polymerase Chain Reaction(PCR) and multi-locus sequence analysis with 16 S r RNA, sod A, hsp65, and ITS genes. The drug sensitivity of the isolate to 27 antibiotics was tested through alamar blue assay. Results Smooth, moist, pale yellow colonies appeared on the L-J medium within a week after inoculation. Based on the results of multiple loci PCR analysis, the isolate was preliminarily identified as non-tuberculous mycobacteria. The 16 S r RNA, Sod A, hsp65, and ITS gene sequences of the isolate exhibited 99%, 99%, 99%, and 100% similarities, respectively, with those of the published reference strains of Mycobacterium elephantis(M. elephantis). The drug sensitivity results showed that the strain is resistant to isoniazid, p-aminosalicylic acid, and trimesulf but is sensitive to ofloxacin, rifampicin, amikacin, capreomycin, moxifloxacin, kanamycin, levofloxacin, cycloserine, ethambutol, streptomycin, tobramycin, rifabutin, ciprofloxacin, linezolid, cefoxitin, clarithromycin, and minocycline. Conclusion To the best of our knowledge, this study is initially to report the isolation of M. elephantis from the milk of a cow with mastitis in China.JI Ling Yun XU Dong Lei YIN Shu Peng LIU Hai Can LI Gui Lian JIANG Yi WEI Jian Hao ZENG Hao LOU Yong Liang LYU Jian Xin WAN Kang Lin 2017Biomedical and Environmental Sciences2017,30,7:1

16Interfacial-Strain-Induced Structural and Polarization Evolutions in Epitaxial Multiferroic BiFeO_3(001) Thin Films显示文摘Varying the film thickness is a precise route to tune the interfacial strain to manipulate the properties of the multiferroic materials.Here,to explore the effects of the interfacial strain on the properties of the multiferroic BiFeO_3films,we investigated thickness-dependent structural and polarization evolutions of the BiFeO_3 films.The epitaxial growth with an atomic stacking sequence of BiO/TiO_2 at the interface was confirmed by scanning transmission electron microscopy.Combining X-ray diffraction experiments and first-principles calculations,a thickness-dependent structural evolution was observed from a fully strained tetragonality to a partially relaxed one without any structural phase transition or rotated twins.The tetragonality(c/a) of the BiFeO_3 films increases as the film thickness decreases,while the polarization is in contrast with this trend,and the size effect including the depolarization field plays a crucial role in this contradiction in thinner films.These findings offer an alternative strategy to manipulate structural and polarization properties by tuning the interfacial strain in epitaxial multiferroic thin films.郭海中 Ruiqiang Zhao Kui-juan Jin Lin Gu Dongdong Xiao Zhenzhong Yang Xiaolong Li Le Wang Xu He Junxing Gu Qian Wan Can Wang Huibin Lu Chen Ge Meng He Guozhen Yang 2015功能材料信息2015,12,3:1
