| 1 | Overview of Mechanism and Mitigation Measures on Multi-frequency Oscillation Caused by Large-scale Integration of Wind Power显示文摘In recent years,the large-scale integration of re-newable energy sources represented by wind power and the widespread application of power electronic devices in power systems have led to the emergence of multi-frequency oscillation problems covering multiple frequency segments,which seriously threaten system stability and restrict the accommodation of renewable energy.The oscillation problems related to renewable energy integration have become one of the most popular topics in the field of wind power integration and power system stability research.It has received extensive attention from both academia and industries with many promising research results achieved to date.This paper first analyzes several typical multi-frequency oscillation events caused by large-scale wind power integration in domestic and foreign projects,then studies the multi-frequency oscillation problems,including wind turbine’s shafting torsional oscillation,sub/super-synchronous oscillation and high frequency resonance.The state of the art is systematically summarized from the aspects of oscillation mechanism,analysis methods and mitigation measures,and the future research directions are explored. | Yongning Chi Bingjie Tang Jiabing Hu Xinshou Tian Haiyan Tang Yan Li Sujuan Sun Lei Shi Lei Shuai | 2019 | CSEE Journal of Power and Energy Systems2019，5，4： | 23 |
| 2 | A Study on Bisphenol A,Nonylphenol,and Octylphenol in Human Urine amples Detected by SPE-UPLC-MS显示文摘Objective To establish a comprehensive analytical method based on SPE‐UPLC‐MS for the simultaneous determination of bisphenol A (BPA), nonylphenol (NP), and octylphenol (OP) in urine samples. Methods Sixty urine samples collected from healthy subjects were analyzed for BPA, NP, and OP concentrations. The samples were de‐conjugated by adding β‐glucuronidase and sulfatase. After the enzymatic treatment, the samples were subjected to the OASIS HLB column solid phase extraction cartridges so as to be cleaned and concentrated. The UPLC separation was performed on a Acquity UPLCTM BEH C18 column (2.1×100 mm, 1.7 μm) with a gradient elution system of methanol‐water as the mobile phase. Triple‐quadrupole mass spectrometry analyzer was used for the qualitative and quantitative analysis of UPLC‐MS/MS system. Results The limit of detection of BPA, NP, and OP was 0.10, 0.10, and 0.15 ng/mL, respectively. The recoveries of BPA, NP and OP were 80.1%‐108%, 81.3%‐109%, and 81.5%‐98.7%, respectively. Among the 60 urine samples, BPA was detected in 8 samples at the level of 0.297‐32.7ng/mL, NP was detected in 29 samples at the level of 1.69‐27.8 ng/mL, and OP was detected in 17 samples at the level of 0.407‐11.1 ng/mL. Conclusion The method is simple with high sensitivity and selectivity, and is suitable for the determination of BPA, NP, and OP in urine. As shown by our analysis , BPA, NP, and OP appear to be prevalent in human urine. This is particularly true for NP. The results from our study is therefore valuable for future studies to assess the exposure to BPA, NP, and OP in the general population. | XIAO Jing SHAO Bing WU XiaoYan SUN XiaoJie WU YongNing | 2011 | Biomedical and Environmental Sciences2011，24，1： | 13 |

| 4 | Regulation of microbiota–GLP1 axis by sennoside A in diet-induced obese mice显示文摘Sennoside A(SA) is a bioactive component of Chinese herbal medicines with an activity of irritant laxative, which is often used in the treatment of constipation and obesity. However, its activity remains unknown in the regulation of insulin sensitivity. In this study, the impact of SA on insulin sensitivity was tested in high fat diet(HFD)-induced obese mice through dietary supplementation. At a dosage of 30 mg/kg/day, SA improved insulin sensitivity in the mice after 8-week treatment as indicated by HOMA-IR(homeostatic model assessment for insulin resistance) and glucose tolerance test(GTT). SA restored plasma level of glucagon-like peptide 1(GLP1) by 90% and mRNA expression of Glp1 by 80% in the large intestine of HFD mice. In the mechanism, SA restored the gut microbiota profile, short chain fatty acids(SCFAs), and mucosal structure in the colon. A mitochondrial stress was observed in the enterocytes of HFD mice with ATP elevation, structural damage, and complex dysfunction. The mitochondrial response was induced in enterocytes by the dietary fat as the same responses were induced by palmitic acid in the cell culture. The mitochondrial response was inhibited in HFD mice by SA treatment. These data suggest that SA may restore the function of microbiota–GLP1 axis to improve glucose metabolism in the obese mice. | Jiamei Le Xiaoying Zhang Weiping Jia Yong Zhang Juntao Luo Yongning Sun Jianping Ye | 2019 | Acta Pharmaceutica Sinica B2019，9，4： | 5 |
| 5 | Characteristics of blood glucose excursions in type 2 diabetes mellitus patients with three different Traditional Chinese Medicine syndromes显示文摘OBJECTIVE:To explore the characteristics of blood glucose excursions of type 2 diabetes mellitus patients with three different Traditional Chinese Medicine(TCM) syndromes.METHODS:One hundred and nine patients with type 2 diabetes mellitus were recruited from the Department of Endocrinology and the Department of TCM of the Sixth People's Hospital affiliated to Shanghai Jiao Tong University.Subjects were divided into three groups according to TCM syndrome:intrinsic Damp(n- 42),Yin deficiency and internal Heat(n = 25),and Qi and Yin deficiency(n- 42).Subcutaneous interstitial glucose was monitored with a continuous glucose monitoring system for 3consecutive days to investigate the glycemic profile in each group.Plasma C-peptide levels were measured,and an arginine test was taken in 10 patients randomly selected from each group.Glucose data and glycemic variability were analyzed to investigate the differences among the groups.The change in C-peptide levels and the results from arginine trial were used to evaluate β cell function.RESULTS:Indicators reflecting blood glucose level were the highest in subjects with Yin deficiency and internal Heat syndrome,and parameters reflecting glycemic variability were the lowest in those with Qi and Yin deficiency syndrome.The change in C-peptide levels showed that subjects with Qi and Yin deficiency syndrome had the best βcell function among the three groups;this was confirmed by the arginine trial.CONCLUSION:Patients with Qi and Yin deficiency syndrome had a more stable blood glucose profile,as glycemic variability was higher in those with intrinsic Damp syndrome and those with Yin deficiency and internal Heat syndrome. | Zhang Hongyan Zhou Jian Zhang Lei Ma Jianhui Sun Yongning Zhao Yuwu | 2015 | Journal of Traditional Chinese Medicine2015，35，5： | 4 |

| 14 | Hierarchical and lamellar porous carbon as interconnected sulfur host and polysulfide-proof interlayer for Li–S batteries显示文摘A robust three-dimensional(3D)interconnected sulfur host and a polysulfide-proof interlayer are key components in high-performance Li–S batteries.Herein,cellulose-based 3D hierarchical porous carbon(HPC)and two-dimensional(2D)lamellar porous carbon(LPC)are employed as the sulfur host and polysulfide-proof inter-layer,respectively,for a Li–S battery.The 3D HPC displays a cross-linked macroporous structure,which allows high sulfur loading and restriction capability and provides unobstructed electrolyte diffusion channels.With a stackable carbon sheet of 2D LPC that has a large plane view size and is ultrathin and porous,the LPC-coated separator effectively inhibits polysulfides.An optimized combination of the HPC and LPC yields an electrode structure that effectively protects the lithium anode against corrosion by polysulfides,giving the cell a high ca-pacity of 1339.4 mAh g^(-1) and high stability,with a capacity decay rate of 0.021% per cycle at 0.2C.This work provides a new understanding of biomaterials and offers a novel strategy to improve the performance of Li–S batteries for practical applications. | Peifan Wang Xin Dai Peng Xu Sijiang Hu Xuyang Xiong Kunyang Zou Shengwu Guo Junjie Sun Chaofeng Zhang Yongning Liu Tengfei Zhou Yuanzhen Chen | 2023 | eScience2023，3，1： | 1 |

| 16 | A Comprehensive AC Fault Ride-through Strategy for HVDC Link with Serial-connected LCC-VSC Hybrid Inverter显示文摘An HVDC link with line-commutated converter(LCC)as a rectifier at the power sending end and with a serial-connected LCC and voltage source converter(VSC)hybrid inverter(SLVHI)at the power receiving end,has been adopted for the forthcoming Baihetan HVDC engineering project in China.To realize the AC fault ride-through(FRT)of SLVHI,a new strategy based on DC chopper(DCC)is proposed in this paper.Firstly,the mathematical model is built to investigate the VSC DC overvoltage mechanism after SLVHI commutation failure(CF)and related factors.Secondly,a modified DCC topology of SLVHI is designed to adjust the unbalanced power dissipation based on voltage drop depth.Thirdly,an enhanced voltage-dependent current order limiter(VDCOL)is proposed to deal with the unbalanced power after DCC switch-off.With the cooperation between modified DCC and enhanced VDCOL,the proposed FRT strategy can realize CF mitigation and VSC DC overvoltage suppression simultaneously.Finally,the inverter side AC FRT performances of the HVDC link with SLVHI were studied using PSCAD software/EMTDC algorithm.The simulation results validate the effectiveness and superiority of the proposed strategy,with better CF mitigation and VSC DC overvoltage suppression abilities than offered by other existing FRT strategies under different fault scenarios. | Fan Cheng Liangzhong Yao Jian Xu Yongning Chi Yuanzhang Sun Zhibing Wang Yan Li | 2022 | CSEE Journal of Power and Energy Systems2022，8，1： | 0 |
| 17 | Hierarchical Control of DC Microgrids Robustness and Smartness显示文摘This paper investigates the hierarchical control of DC microgrids.Compared to AC microgrids,DC microgrids encounter complicated converter-level control,and simplified system-level management.To address these characteristics,a new three-level control hierarchy is introduced.The converter control level encapsulates sophisticated converter topologies and inner control loops into a black-box representation.The voltage coordination level uses DC voltage signals to coordinate both static and transient power sharing.The energy management level optimizes the power flow and power quality in a broader scope through communication.This architecture lowers the focus of control to bottom levels.More functions are allocated to the converter control and voltage coordination levels.They can maintain basic microgrid performance with fully local control,thereby ensuring reliable power supply in case of communication failures.Moreover,taking advantage of DC microgrids’simplified system-level operation patterns,the energy management level uses straightforward algorithms to achieve intelligent functions.As a result,this architecture achieves both robust and smart control by exploring DC microgrids’critical features. | Yunjie Gu Heya Yang Wei Sun Yongning Chi Wuhua Li Xiangning He | 2020 | CSEE Journal of Power and Energy Systems2020，6，2： | 0 |
