| 1 | A novel LMI criterion for power system stability with multiple time-delays显示文摘This paper presents a novel LMI criterion for electric power system stability with multiple time-delays.Initially,the linear time-invariant model of the power system with multiple delays is constructed,subsequently,the former criteria and the novel criterion of this paper are demonstrated in this paper,and the novel criterion is fully proved according to Lyapunov direct method.Specifically,the proposed criterion utilizes a properly simplified Lyapunov-Krasovskii functional,and no free-weighting matrix is introduced in the formation of new criterion,as a consequence,the calculation efficiency is remarkably enhanced.A typical second-order delay system,a single-generator-infinite-bus system and the WSCC 3-generator-9-bus delay system are taken to validate the effectiveness and efficiency enhancement of the proposed criterion.The numerical results indicate that the criterion of this paper can generate the same stability margin with the former ones.Further,the numerical results also verify that the proposed criterion’s efficiency is substantially boosted and calculation time is greatly curtailed. | JIANG YiLang JIANG Tao JIA HongJie DONG ChaoYu | 2014 | Science China(Technological Sciences)2014，57，7： | 13 |
| 2 | Numerical study on the correlation of transonic single-degree-of-freedom flutter and buffet显示文摘Transonic single-degree-of-freedom(SDOF) flutter and transonic buffet are the typical and complex aeroelastic phenomena in the transonic flow. In this study, transonic aeroelastic issues of an elastic airfoil are investigated using Unsteady Reynolds-Averaged Navier-Stokes(URANS) equations. The airfoil is free to vibrate in SDOF of pitching. It is found that, the coupling system may be unstable and SDOF self-excited pitching oscillations occur in pre-buffet flow condition, where the free-stream angle of attack(AOA) is lower than the buffet onset of a stationary airfoil. In the theory of classical aeroelasticity, this unstable phenomenon is defined as flutter. However, this transonic SDOF flutter is closely related to transonic buffet(unstable aerodynamic models) due to the following reasons. Firstly, the SDOF flutter occurs only when the free-stream AOA of the spring suspended airfoil is slightly lower than that of buffet onset, and the ratio of the structural characteristic frequency to the buffet frequency is within a limited range. Secondly, the response characteristics show a high correlation between the SDOF flutter and buffet. A similar 'lock-in' phenomenon exists, when the coupling frequency follows the structural characteristic frequency. Finally, there is no sudden change of the response characteristics in the vicinity of buffet onset, that is, the curve of response amplitude with the free-stream AOA is nearly smooth. Therefore, transonic SDOF flutter is often interwoven with transonic buffet and shows some complex characteristics of response, which is different from the traditional flutter. | GAO ChuanQiang ZHANG WeiWei LIU YiLang YE ZhengYin JIANG YueWen | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，8： | 4 |

| 4 | Fast frequency response of inverter-based resources and its impact on system frequency characteristics显示文摘The inertia response and primary frequency regulation capability of synchronous grids are declining owing to the increasing penetration of inverter-based resources. The fast frequency response(FFR) of inverter-based resources is an important mitigation option for maintaining grid security under the conditions of low inertia and insufficient primary frequency response capability. However, the understanding and technical characteristics of the FFR of inverter-based resources are still unclear. Aiming at solving the aforementioned problems, this paper proposes a definition for FFR based on the impact mechanism of FFR on system frequency. The performance requirements of FFR are clarified. Then, the effects of FFR on system frequency characteristics are further analyzed based on steady-state frequency deviation, the initial rate of change of frequency, and the maximum transient frequency deviation. Finally, the system requirements for FFR and its application effects are verified by simulating an actual bulk power grid, providing technical support for subsequent engineering application. | Lining Su Xiaohui Qin Shang Zhang Yantao Zhang Yilang Jiang Yi Han | 2020 | Global Energy Interconnection2020，3，5： | 1 |

| 6 | Immunostimulant nanomodulator boosts antitumor immune response in triple negative breast cancer by synergism of vessel normalization and photothermal therapy显示文摘Tumor vascular dysfunction and immune suppression predict poor outcomes of tumor therapy.Combination of photothermal therapy(PTT)and vessel normalization with tumor immunotherapy is promising to augment antitumor benefit.Herein,we develop a potential immunostimulatory nanomodulator for treatment of triple-negative breast cancer(TNBC)treatment via synergism of PTT,vessel normalization,and priming of tumoral suppressive immune microenvironment by blocking transforming growth factor-β(TGF-β)pathway.The nanomodulator,namely Vac@Apt@BPs,is developed by conjugation of TGF-βinhibitor Vactosertib(Vac)and nucleolin-recognizing aptamer(Apt)on the surface of black phosphorus nanoparticles(BPs).Vac@Apt@BPs show good accumulation in TNBC via aptamer-induced active targeting of TNBC.Via the blockade of TGF-βsignaling,Vac@Apt@BPs effectively inhibit the formation of tumor neovascular,and normalize the vessels to recover vascular integrity and alleviate the hypoxia stress.Together with the tumor eradication and immunogenic cell death via PTT,robust immune response was boosted by promoted maturation of dendritic cells,suppression of regulatory T cells,and stimulation of effective T cells.This synergistic therapeutic strategy potentially suppresses the growth of TNBC in mice. | Hao Jiang Yilang He Jia Zhao Ruimin Chang Hailun He Tan Li Xingyu Zhang Bo Shu Wenxuan Zhang Huaiyu Wang Jing Liu Shubing Zhang Yuetao Zhao | 2023 | Nano Research2023，16，8： | 0 |
