| 1 | Control of hybrid AC/DC microgrid under islanding operational conditions显示文摘This paper presents control methods for hybrid AC/DC microgrid under islanding operation condition.The control schemes for AC sub-microgrid and DC sub-microgrid are investigated according to the power sharing requirement and operational reliability.In addition,the key control schemes of interlinking converter with DC-link capacitor or energy storage,which will devote to the proper power sharing between AC and DC sub-microgrids to maintain AC and DC side voltage stable,is reviewed.Combining the specific control methods developed for AC and DC sub-microgrids with interlinking converter,the whole hybrid AC/DC microgrid can manage the power flow transferred between sub-microgrids for improving on the operational quality and efficiency. | Guangqian DING Feng GAO Song ZHANG Poh Chiang LOH Frede BLAABJERG | 2014 | Journal of Modern Power Systems and Clean Energy2014，2，3： | 23 |
| 2 | Characteristics of gas-solid micro fluidized beds for thermochemical reaction analysis显示文摘Fuel conversion and clean energy reaction systems involve a variety of catalytic and non-catalytic gas-solid thermochemical reactions.A good understanding of the correct reaction mechanism and kinetics,as well as the profiles of reaction products,is of great significance to the development,design,and operation of such reaction systems.The micro fluidized bed reaction analysis provides an efficient and reliable method to acquire this essential information with low capital and operating costs,low energy consumption and enhanced safety.This paper provides an overview of the system and its characteristics for the micro fluidized bed reaction analyzer that has been well proven to be a reliable new approach as well as an instrument for characterizing various gas-solid thermochemical reactions. | Zhennan Han Junrong Yue Xi Zeng Jian Yu Fang Wang Shaozeng Sun Hong Yao Guangqian Luo Xuejing Liu Yining Sun Fu Ding Liangliang Fu Lei Shi Kangjun Wang Jiebin Yang Shaonan Wang Xueqing Chen Dingrong Bai Guangwen Xu | 2020 | Carbon Resources Conversion2020，3，1： | 6 |
| 3 | Communication-less harmonic compensation in a multi-bus microgrid through autonomous control of distributed generation grid-interfacing converters显示文摘This paper proposes a novel approach to compensate buses voltage and current harmonics through distributed generation(DG)interfacing converter in a multibus microgrid.The control approach of each individual DG unit was designed to use only feedback variables of the converter itself that can be measured locally.In the proposed approach,the adjacent bus voltage is indirectly derived from the measured DG converter output voltage,DG line current and line impedance.A voltage closed-loop controller and a current closed-loop controller are designed to achieve both functions of DG real power generation and harmonics compensation.Therefore,the traditional harmonic measurement devices installed at the bus as well as the long distance communication between the bus and the DG converter are not required.The proposed approach can compensate the current harmonics,mitigate the buses voltage distortion and enable the customer devices to be operated in normal conditions within the multi-bus microgrid,and meanwhile relieve the burden of power quality regulator installed at the point of common coupling.Matlab simulations and experimental results are presented to show the operational effectiveness of the proposed approach. | Guangqian DING Ran WEI Ke ZHOU Feng GAO Yi TANG | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，4： | 5 |

| 6 | Dual-Driven Hemostats Featured with Puncturing Erythrocytes for Severe Bleeding in Complex Wounds显示文摘Achieving rapid hemostasis in complex and deep wounds with secluded hemorrhagic sites is still a challenge because of the difficulty in delivering hemostats to these sites.In this study,a Janus particle,SEC-Fe@CaT with dual-driven forces,bubble-driving,and magnetic field–(MF–)mediated driving,was prepared via in situ loading of Fe_(3)O_(4) on a sunflower sporopollenin exine capsule(SEC),and followed by growth of flower-shaped CaCO3 clusters.The bubble-driving forces enabled SEC-Fe@CaT to self-diffuse in the blood to eliminate agglomeration,and the MF-mediated driving force facilitated the SEC-Fe@CaT countercurrent against blood to access deep bleeding sites in the wounds.During the movement in blood flow,the meteor hammer-like SEC from SEC-Fe@CaT can puncture red blood cells(RBCs)to release procoagulants,thus promoting activation of platelet and rapid hemostasis.Animal tests suggested that SEC-Fe@CaT stopped bleeding in as short as 30 and 45 s in femoral artery and liver hemorrhage models,respectively.In contrast,the similar commercial product Celox™required approximately 70 s to stop the bleeding in both bleeding modes.This study demonstrates a new hemostat platform for rapid hemostasis in deep and complex wounds.It was the first attempt integrating geometric structure of sunflower pollen with dual-driven movement in hemostasis. | Haoyu Qiu Guangqian Lan Weiwei Ding Xinyu Wang Wenyi Wang Dahua Shou Fei Lu Enling Hu Kun Yu Songmin Shang Ruiqi Xie | 2022 | Research2022，，4： | 0 |
| 7 | Abnormal thermal conductivity enhancement in covalently bonded bilayer borophene allotrope显示文摘Thermal conductivity of two-dimensional(2D)materials has gained prominence due to the attractive applications in thermal management and thermoelectric devices.In this work,we present a new member of bilayer 2D boron allotropes,denoted as bilayerβ12 borophene,and study the thermal transport properties by solving phonon Boltzmann transport equation based on density functional theory.Based on quantitative chemical bonding analysis,we identify large degrees of covalent bonding of the interlayer interaction.In comparison to its monolayer counterpart,the bilayer exhibits much higher in-plane thermal conductivity despite the lower phonon group velocity and buckling structure,inferring a new physical mechanism.The thermal conductivity(κ)of bilayerβ_(12)borophene at 300 K is 140.5(86.3)W·m^(-1)·K^(-1)along armchair(zigzag)direction,andκ_(armchair)is about 52.7%higher than that of monolayerβ12 borophene.The abnormal enhancement is attributed to the suppressed phonon scattering possibility and elongation of phonon lifetime.More interesting,after forming bilayerβ12 borophene through interlayer covalent bonding,the dominated phonon branch to thermal conductivity changes to transverse acoustic phonons from out-of-plane flexural acoustic(ZA)phonons in the monolayer borophene.Our study elucidates the rich thermal transport characteristics in bilayer covalently bonded 2D materials,and injects fresh insights into the phonon engineering of 2D borophene relevant for emergent thermal management applications. | Yan Yin Yanxiao Hu Shichang Li Guangqian Ding Shifa Wang Dengfeng Li Gang Zhang | 2022 | Nano Research2022，15，4： | 0 |
