| 1 | A Day-ahead Economic Dispatch Method Considering Extreme Scenarios Based on Wind Power Uncertainty显示文摘As the intermittency of wind power is a growing concern in the day-ahead economic dispatch,this paper proposes a day-ahead economic dispatch method considering extreme scenarios of wind power by using an uncertainty set.The uncertainty set inspired by robust optimization is used to describe wind power intermittency in this paper.Four extreme scenarios based on the uncertainty set are formulated to represent the worst cases of wind power fluctuation.An economic dispatch method considering the costs of both load shedding and wind curtailment is proposed.The economic dispatch model can be easily solved by a quadratic programming method owing to the introduction of four extreme scenarios and the uncertainty set of wind power.Simulation is done using the IEEE 30-bus system and the results verify the effectiveness of the proposed method. | Jian Xu Bao Wang Yuanzhang Sun Qi Xu Ji Liu Huiqiu Cao Haiyan Jiang Ruobing Lei Mengjun Shen | 2019 | CSEE Journal of Power and Energy Systems2019，5，2： | 5 |
| 2 | Superconducting gap evolution of kagome metal CsV3Sb5 under pressure显示文摘Kagome superconductors AV3Sb5(A=Cs,V,Sb) have served as an ideal platform to unveil the intriguing competitions between charge-density-wave(CDW),superconductivity and possible nontrivial topological states.We report soft point-contact spectroscopy(SPCS) studies on CsV3Sb5under pressure up to 2.5 GPa.Its superconducting transition temperature Tcand gaps for SPCS at pressure P=0.1 GPa suggest the absence of the adverse local strain effect as observed in point-contacts at ambient pressure,while the SPCS-determined Tcunder hydrostatic pressure deviates from the reported double dome feature below 2.5 GPa.Three distinct gap values in CsV3Sb5are proposed to exist through the whole pressure range with 2Δ1/kBTc≤1,2Δ2/kBTc~2.3-3.0 and 2Δ3/kBTc>3.5.The two smaller gaps for 2Δ1/kBTc≤1 and 2Δ2/kBTc~2.3-3.0 are robust under pressure,while there is no trace of the largest gap 2Δ3/kBTc>3.5 for SPCS in the c direction with P≤P1=0.7 GPa and P≥ P2=2.0 GPa and it becomes observable in the pressure range of(P1,P2),suggesting a complex relation between CDW and superconductivity between(P1,P2). | Dongting Zhang Chufan Chen Lichang Yin Yan'En Huang Fengrui Shi Yi Liu Xiaofeng Xu Huiqiu Yuan Xin Lu | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，2： | 2 |
| 3 | Implementation technology of Kirchhoff demigration显示文摘Demigration refers to directly applying a specific imaging technique to a migrated section. It is applied primarily to seismic data mapping. In a previous research study,a time-efficient implementation technology of demigration was expounded. In the present study,the Fast Marching Method( FMM) used for traveltime computation in the isochrone-stack demigration,is developed. Furthermore,other key techniques( such as selection of aperture and antialiasing filtering factor) are analyzed in detail. Besides,the detail implementation method and program flow are given,which is shown their good computational efficiency and high-quality demigration effect. This implementation technique is illustrated with both the V( z) model and Marmousi model. It provides a basic method for implementing demigration in the application of seismic data mapping. | XU Yangyang SUN Jianguo SUN Hui SUN Huiqiu JIANG Panpan ZHAO Sihang | 2015 | Global Geology2015，18，4： | 1 |

| 5 | Cultural Practices for Edible Roses in the Open Field in Tropical Areas显示文摘The edible rose was planted on trial in Hainan under the tropical oceanic climate environment according to its botanic characteristics and growth habit.A set of cultural practices suitable for the edible rose planted in Hainan was summarized,including land selection,land preparation,variety selection,planting requirements,field management,pruning,flowering regulation,and control of pests and diseases. | Yilei ZHANG Huiqiu XU Hailiang ZHANG Shiyang HONG Jingtian LI Taihao CHEN Jingpin LIANG Guangying ZHAO | 2018 | Agricultural Biotechnology2018，7，1： | 0 |
| 6 | On the Economic Benefits of Cut Roses Planting in Sanya显示文摘The study aims to promote the off-season cut roses industry in Hainan Province to the whole island and even whole China. Based on the production data in latest three years,the theory of time value was introduced to analyze the economic benefits of cut roses planting in South Hainan. According to the research findings,the cut roses create a NPV of $22 000 /667m2 with a net NPV rate of 34. 24%,an internal rate of return of 76. 36%,and a dynamic payback of 1. 05,bringing the farmers a revenue of $7 200 /667m2 per capita per year. Since the largescale planting of cut roses needs a high investment,it is suggested that the government should increase its support for the cut rose industry. | Yaqiong LIN Guanming CHEN Huiqiu XU Liping WANG | 2013 | Asian Agricultural Research2013，5，10： | 0 |
| 7 | Occurrence Characteristics,Prevention and Control of Pests and Diseases of Tropical Outdoor Cultivated Rosa chinensis显示文摘According to the hazards and occurrence characteristics of major diseases of Rosa chinensis,such as powdery mildew,branch canker and black spot,and major pests such as mites,aphids,thrips and Lepidoptera,prevention and control of the diseases and pests should be based on pruning,garden cleaning,water and fertilizer management,and chemical control can be applied as the supplement. Suitable prevention and control measures should be adopted for preventing the diseases and pests scientifically. | Lin Hengmi Xu Huiqiu Zhang Hailiang Qiao Shunfa Hong Shiyang Zhang Yilei Li Jingtian Chen Xingyu | 2014 | Plant Diseases and Pests2014，5，6： | 0 |
