1A Li-S battery with ultrahigh cycling stability and enhanced rate capability based on novel ZnO yolk-shell sulfur host显示文摘Currently,lithium-sulfur(Li-S)batteries still suffer from fast capacity decay,poor coulombic efficiency(CE)and short cycling lifespan,which result from the severe shuttle effect issue caused by high solubility and rapid diffusion of lithium polysulfides(Li PSs)in organic electrolytes.Here,yolk-shell zinc oxide(YSZn O)spheres are synthesized and for the first time,applied as a host for Li-S batteries to tackle this challenge.The polar Zn O exhibits high chemical anchoring ability toward Li PSs while the unique yolk-shell structure not only provides an additional physical barrier to Li PSs but also enables much more uniform sulfur distribution,thus significantly suppressing Li PSs shuttling effect meanwhile promoting sulfur conversion reactions.As a result,the YS-Zn O enables the Li-S battery to display an initial specific capacity of1355 m Ah g^(-1) and an outstanding capacity retention capability(~89.44%retention rate)even after 500 cycles with the average CE of~99.46%at the current of 0.5 C.By contrast,the capacity of conventional-Zn O-nanoparticles based battery severely decays to 472 m Ah g^(-1) after cycling for 500 times.More impressively,the S/YS-Zn O based Li-S battery can maintain a low decay rate of 0.040%every cycle and high average CE of 98.82%over 1000 cycles at 3 C.Ruihan Zhang Maochun Wu Xinzhuang Fan Haoran Jiang Tianshou Zhao 2021Journal of Energy Chemistry2021,30,4:5
2A novel energy storage system incorporating electrically rechargeable liquid fuels as the storage medium显示文摘We propose a novel concept of energy storage that incorporates electrically rechargeable liquid fuels made of electroactive species, known as e-fuels, as the storage medium. This e-fuel energy storage system comprises an e-fuel charger and an e-fuel cell. The e-fuel charger electrically charges e-fuels, while the efuel cell subsequently generates electricity using charged e-fuels whenever and wherever on demand.The e-fuel energy storage system possesses all the advantages of conventional hydrogen storage systems,but unlike hydrogen, liquid e-fuels are as easy and safe to store and transport as gasoline. The potential efuel candidates have been identified to include inorganic electroactive materials, organic electroactive materials, and suspension of solid electroactive materials. In this work, we demonstrate an example efuel energy storage system for large-scale energy storage using inorganic e-fuels composed of V^(2+)/V^(3+) and VO_2^+/VO_2^+ redox couples, and compare the performance of the e-fuel energy storage system with that of existing technologies. Results show that our e-fuel charger achieves a charge efficiency of as high as~94%, while the e-fuel cell is capable of delivering a peak power density of 3.4 W cm^(-2), which is 1.7 times higher than that of hydrogen fuel cells. More excitingly, the e-fuel energy storage system exhibits a round-trip efficiency of 80.0% and an electrolyte utilization of 83.0% at an ultra-high discharge current density of 1,000 mA cm^(-2), which are 19.9% and 67.3% higher than those of conventional vanadium redox flow batteries. This unprecedented performance allows a 27.0% reduction in the capital cost of the e-fuel energy storage system compared with that of vanadium redox flow batteries.Haoran Jiang Lei Wei Xinzhuang Fan Jianbo Xu Wei Shyy Tianshou Zhao 2019Science Bulletin2019,64,4:2
3Microfluidic chips for the endothelial biomechanics and mechanobiology of the vascular system显示文摘Endothelial cells arranged on the vessel lumen are constantly stimulated by blood flow,blood pressure and pressureinduced cyclic stretch.These stimuli are sensed through mechanical sensory structures and converted into a series of functional responses through mechanotransduction pathways.The process will eventually affect vascular health.Therefore,there has been an urgent need to establish in vitro endothelial biomechanics and mechanobiology of models,which reproduce three-dimensional structure vascular system.In recent years,the rapid development in microfluidic technology makes it possible to replicate the key structural and functionally biomechanical characteristics of vessels.Here,we summarized the progress of microfluidic chips used for the investigation of endothelial biomechanics and mechanobiology of the vascular system.Firstly,we elucidated the contribution of shear stress and circumferential stress,to vascular physiology.Then,we reviewed some applications using microfluidic technology in angiogenesis and vasculogenesis,endothelial permeability and mechanotransduction,as well as the blood-brain barrier under these physical forces.Finally,we discussed the future obstacles in terms of the development and application of microfluidic vascular chips.HAORAN SU KEXIN LI XIAO LIU JING DU LI WANG XIAOYAN DENG YUBO FAN 2021BIOCELL2021,45,4:2
4The effect of mechanical loads on the degradation of aliphatic biodegradable polyesters显示文摘Aliphatic biodegradable polyesters have been the most widely used synthetic polymers for developing biodegradable devices as alternatives for the currently used permanent medical devices.The performances during biodegradation process play crucial roles for final realization of their functions.Because physiological and biochemical environment in vivo significantly affects biodegradation process,large numbers of studies on effects of mechanical loads on the degradation of aliphatic biodegradable polyesters have been launched during last decades.In this review article,we discussed the mechanism of biodegradation and several different mechanical loads that have been reported to affect the biodegradation process.Other physiological and biochemical factors related to mechanical loads were also discussed.The mechanical load could change the conformational strain energy and morphology to weaken the stability of the polymer.Besides,the load and pattern could accelerate the loss of intrinsic mechanical properties of polymers.This indicated that investigations into effects of mechanical loads on the degradation should be indispensable.More combination condition of mechanical loads and multiple factors should be considered in order to keep the degradation rate controllable and evaluate the degradation process in vivo accurately.Only then can the degradable devise achieve the desired effects and further expand the special applications of aliphatic biodegradable polyesters.Ying Li Zhaowei Chu Xiaoming Li Xili Ding Meng Guo Haoran Zhao Jie Yao Lizhen Wang Qiang Cai Yubo Fan 2017Regenerative Biomaterials2017,4,3:2
5Genome-wide analysis of NDR1/HIN1-like genes in pepper(Capsicum annuum L.)and functional characterization of CaNHL4 under biotic and abiotic stresses显示文摘Plant NDR1/HIN1-like(NHL)genes play an important role in triggering plant defenses in response to biotic stresses.In this study,we performed a genome-wide identification of the NHL genes in pepper(Capsicum annuum L.)and characterized the functional roles of these CaNHL genes in response to abiotic stresses and infection by different pathogens.Phylogenetic analysis revealed that CaNHLs can be classified into five distinct subgroups,with each group containing generic and specific motifs.Regulatory element analysis showed that the majority of the promoter regions of the identified CaNHLs contain jasmonic acid(JA)-responsive and salicylic acid(SA)-responsive elements,and transcriptomic analysis revealed that CaNHL genes are expressed in all the examined tissues of pepper.The CaNHL1,CaNHL4,CaNHL6,CaNHL10,CaNHL11,and CaNHL12 genes were significantly upregulated under abiotic stress as well as in response to different pathogens,such as TMV,Phytophthora capsici and Pseudomonas syringae.In addition,we found that CaNHL4 localizes to the plasma membrane.CaNHL4-silenced pepper plants display significantly increased susceptibility to TMV,Phytophthora capsici and Pseudomonas syringae,exhibiting reduced expression of JA-related and SA-related genes and reduced ROS production.However,transient overexpression of CaNHL4 in pepper increases the expression of JArelated and SA-related genes,enhances the accumulation of ROS,and inhibits the infection of these three pathogens.Collectively,for the first time,we identified the NHL genes in pepper and demonstrated that CaNHL4 is involved in the production of ROS and that it also regulates the expression of JA-related and SA-related genes in response to different pathogens,suggesting that members of the CaNHL family play an essential role in the disease resistance of pepper.Changyun Liu Haoran Peng Xinyu Li Chaolong Liu Xing Lv Xuefeng Wei Aihong Zou Jian Zhang Guangjin Fan Guanhua Ma Lisong Ma Xianchao Sun 2020Horticulture Research2020,7,1:2
6Temporal-spatial distributions of road silt loadings and fugitive road dust emissions in Beijing from 2019 to 2020显示文摘Road silt loading(sL)is an important parameter in the fugitive road dust(FRD)emissions.In this study,the improved Testing Re-entrained Aerosol Kinetic Emissions from Roads(TRAKER)combined with the AP-42 method was firstly developed to quickly measure and estimate the sLs of paved roads in Beijing,China.The annual average sLs in Beijing was 0.59±0.31 g/m^(2)in 2020,and decreased by 22.4%compared with that in 2019.The seasonal variations of sLs followed the order of spring>winter>summer>autumn in the two years.The seasonal mean road sLs on the same type road in the four seasons presented a decline trend from^(2)019 to 2020,especially on the Expressway,decreasing 47.4%-72.7%.The road sLs on the different type roads in the same season followed the order of Major arterial∼Minor arterial∼Branch road>Express road,and Township road∼Country highway>Provincial highway∼National highway.The emission intensities of PM10 and PM_(2.5)from FRD in Beijing in 2020 were lower than those in 2019.The PM10 and PM_(2.5)emission intensities at the four planning areas in the two years all presented the order of the capital functional core area>the urban functional expansion area>the urban development new area>the ecological conservation and development area.The annual emissions of PM10 and PM_(2.5)from FRD in Beijing in 2020 were 74,886 ton and 18,118 ton,respectively,decreasing by∼33.3%compared with those in 2019.Haibin Wang Lihui Han Tingting Li Song Qu Yuncheng Zhao Shoubin Fan Tong Chen Haoran Cui Junfang Liu 2023Journal of Environmental Sciences2023,,10:1
7Decoupling engineering of formamidinium–cesium perovskites for efficient photovoltaics显示文摘Although pure formamidinium iodide perovskite(FAPbI3)possesses an optimal gap for photovoltaics,their poor phase stability limits the long-term operational stability of the devices.A promising approach to enhance their phase stability is to incorporate cesium into FAPbI3.However,state-of-the-art formamidinium–cesium(FA–Cs)iodide perovskites demonstrate much worse efficiency compared with FAPbI3,limited by the different crystallization dynamics of formamidinium and cesium,which result in poor composition homogeneity and high trap densities.We develop a novel strategy of crystallization decoupling processes of formamidinium and cesium via a sequential cesium incorporation approach.As such,we obtain highly reproducible,highly efficient and stable solar cells based on FA_(1–x)Cs_(x)PbI_(3)(x=0.05–0.16)films with uniform composition distribution in the nanoscale and low defect densities.We also revealed a new stabilization mechanism for Cs doping to stabilize FAPbI3,i.e.the incorporation of Cs into FAPbI3 significantly reduces the electron–phonon coupling strength to suppress ionic migration,thereby improving the stability of FA–Cs-based devices.Haoran Chen Yong Wang Yingping Fan Yuetian Chen Yanfeng Miao Zhixiao Qin Xingtao Wang Xiaomin Liu Kaicheng Zhu Feng Gao Yixin Zhao 2022National Science Review2022,9,10:1

9The SACT Template:A Human Brain Diffusion Tensor Template for School-age Children显示文摘School-age children are in a specific development stage corresponding to juvenility,when the white matter of the brain experiences ongoing maturation.Dffusion-weighted magnetic resonance imaging(DWI),especially diffusion tensor imaging(DTI),is extensively used to characterize the maturation by assessing white matter properties in vivo.In the analysis of DWI data,spatial normalization is crucial for conducting inter-subject analyses or linking the individual space with the reference space.Using tensor-based registration with an appropriate diffusion tensor template presents high accuracy regarding spatial normalization.However,there is a lack of a standardized diffusion tensor template dedicated to school-age children with ongoing brain development.Here,we established the school-age children diffusion tensor(SACT)template by optimizing tensor reorientation on high-quality DTI data from a large sample of cognitively normal participants aged 6-12 years.With an age-balanced design,the SACT template represented the entire age range well by showing high similarity to the age-specific templates.Compared with the tensor template of adults,the SACT template revealed significantly higher spatial normalization accuracy and inter-subject coherence upon evaluation of subjects in two different datasets of schoolage children.A practical application regarding the age associations with the normalized DTI-derived data was conducted to further compare the SACT template and the adult template.Although similar spatial patterns were found,the SACT template showed significant effects on the distributions of the statistical results,which may be related to the performance of spatial normalization.Looking forward,the SACT template could contribute to future studies of white matter development in both healthy and clinical populations.The SACT template is publicly available now(tp://igshare com/aricles/dataseu'SACT_.template/14071283).Congying Chu Haoran Guan Sangma Xie Yanpei Wang Jie Luo Gai Zhao Zhiying Pan Mingming Hu Weiwei Men Shuping Tan Jia-Hong Gao Shaozheng Qin Yong He Lingzhong Fan Qi Dong Sha Tao 2022Neuroscience Bulletin2022,38,6:1
10Phase transferring luminescent gold nanoclusters via single-stranded DNA显示文摘Atomically precise gold nanoclusters(Au NCs) are an emerging class of quantum-sized nanomaterials with discrete electronic energy levels, which has led to a range of attractive electronic and optical applications. Nevertheless, the lack of general methods to transfer Au NCs protected with hydrophobic ligands to an aqueous solution hampers their use in physiological settings. Here,we developed a single-stranded DNA-based approach that could transfer ~90% hydrophobic Au NCs into an aqueous solution.We experimentally and theoretically established that multivalent electrostatic and hydrophobic interactions between DNA strands and the hydrophobic ligand layer on Au NCs resulted in monodispersed DNA-coated Au NCs with high physical integrity in an aqueous solution. The fluorescence quantum yield of Au NCs was increased by ~13 fold, and surface-constrained DNA retained the specific recognition ability for biosensing. We further demonstrated the versatility of this phase-transfer approach, which thus holds great potential to advance biological and medical applications of Au NCs.Yu Li Hui Lu Zhibei Qu Mingqiang Li Haoran Zheng Peilin Gu Jiye Shi Jiang Li Qian Li Lihua Wang Jing Chen Chunhai Fan Jianlei Shen 2022Science China Chemistry2022,65,6:1
11Efficacy and complications of inoperable malignant distal biliary obstruction treatment by metallic stents:fully covered or uncovered?显示文摘Obstructive jaundice caused by malignant distal biliary obstruction is a common clinical symptom in patients with inoperable biliary–pancreatic cancer.Endoscopic retrograde cholangiopancreatography(ERCP)-guided stent implantation is an effective treatment for obstructive jaundice.Internal stent drainage is more physiologic and associated with a better quality of life than external stent drainage methods such as percutaneous transhepatic gallbladder drainage or percutaneous transhepatic cholangiodrainage.Selfexpanding metallic stents,which may be covered and uncovered,are commonly used.However,some uncertainties remain regarding the selection of metallic stents,including drainage patency time,clinical effect,stent migration,and post-operative complications such as pancreatitis,bleeding,and cholecystitis.This review aims to summarize the current progress and controversies surrounding the use of covered or uncovered metallic stents in inoperable common biliary obstruction via ERCP.Jiangning Gu Xiaoyi Guo Yong Sun Bin Fan Haoran Li Ting Luo Haifeng Luo Jiao Liu Feng Gao Yuan Gao Guang Tan Xiaoming Liu Zhuo Yang 2023Gastroenterology Report2023,11,1:0

13Asymmetric MXene/monolayer transition metal dichalcogenide heterostructures for functional applications显示文摘A versatile two-dimensional(2D)molecular bilayer heterostructure of asymmetric MXene/monolayer transition metal dichalcogenide(aMXene/mTMDC)with a high interfacial built-in electric field is here simulated,where aMXene is an aMXene with the top or bottom electronegative atom plane of MXene removed.The asymmetric structural design of aMXene leads to a high dipole moment perpendicular to the 2D molecular plane.Although the unpassivated metal atoms in the aMXene are unstable and electropositive,coupling them to the electronegative chalcogenide atoms in an aMXene/mTMDC bilayer resolves this deficiency.The dipole field tunable by the specific composition of aMXene/mTMDC is leveraged to engineer unusual band structures,band alignments,and charge redistribution/injection in the bilayer.The simulated design of several aMXene/mTMDC bilayers for possible use in spintronics,microelectronics/optoelectronics,and catalysis/photocatalysis are shown.Baihai Li Haoran Guo Yunrui Wang Wenxu Zhang Qiuju Zhang Liang Chen Xiaoli Fan Wanli Zhang Yanrong Li Woon-Ming Lau 2019npj Computational Materials2019,,1:0
14Single-axis ultrasound levitation system with annular clamping forces显示文摘Based on the principle of acoustic levitation,a single-axis ultrasonic levitation system(SAULS) with convex sides was designed.A normal SAULS only provides a levitation force(LF) against the gravity of the sample.While,such systems also provide an annular clamping force(ACF) surrounding the levitated samples,and improve levitation stability of samples in the standing wave field.Using the finite-difference time-domain method,we investigated the force distributions in different resonance cavities and the factors that influence the magnitude of the levitation force in optimizing the SAULS and the ACF.The theoretical analyses and experimental results indicate that the stability of levitation in this special SAULS is improved with the ACF from its designed convex-side feature.It can be developed into a simple device in levitating and moving samples steadily in related experiments and applications.YIN Guanjun LI Pan FAN Haoran GUO Jianzhong 2019Chinese Journal of Acoustics2019,38,2:0
15A review of interaction mechanisms and microscopic simulation methods for CO_(2)-water-rock system显示文摘This work systematically reviews the complex mechanisms of CO_(2)-water-rock interactions,microscopic simulations of reactive transport(dissolution,precipitation and precipitate migration)in porous media,and microscopic simulations of CO_(2)-water-rock system.The work points out the key issues in current research and provides suggestions for future research.After injection of CO_(2) into underground reservoirs,not only conventional pressure-driven flow and mass transfer processes occur,but also special physicochemical phenomena like dissolution,precipitation,and precipitate migration.The coupling of these processes causes complex changes in permeability and porosity parameters of the porous media.Pore-scale microscopic flow simulations can provide detailed information within the three-dimensional pore and throat space and explicitly observe changes in the fluid-solid interfaces of porous media during reactions.At present,the research has limitations in the decoupling of complex mechanisms,characterization of differential multi-mineral reactions,precipitation generation mechanisms and characterization(crystal nucleation and mineral detachment),simulation methods for precipitation-fluid interaction,and coupling mechanisms of multiple physicochemical processes.In future studies,it is essential to innovate experimental methods to decouple“dissolution-precipitation-precipitate migration”processes,improve the accuracy of experimental testing of minerals geochemical reaction-related parameters,build reliable characterization of various precipitation types,establish precipitation-fluid interaction simulation methods,coordinate the boundary conditions of different physicochemical processes,and,finally,achieve coupled flow simulation of“dissolution-precipitation-precipitate migration”within CO_(2)-water-rock systems.ZHANG Liehui ZHANG Tao ZHAO Yulong HU Haoran WEN Shaomu WU Jianfa CAO Cheng WANG Yongchao FAN Yunting 2024Petroleum Exploration and Development2024,51,1:0
16PUMD:a PU learning-based malicious domain detection framework显示文摘Domain name system(DNS),as one of the most critical internet infrastructure,has been abused by various cyber attacks.Current malicious domain detection capabilities are limited by insufficient credible label information,severe class imbalance,and incompact distribution of domain samples in different malicious activities.This paper proposes a malicious domain detection framework named PUMD,which innovatively introduces Positive and Unlabeled(PU)learning solution to solve the problem of insuffcient label information,adopts customized sample weight to improve the impact of class imbalance,and effectively constructs evidence features based on resource overlapping to reduce the intra-class distance of malicious samples.Besides,a feature selection strategy based on permutation importance and binning is proposed to screen the most informative detection features.Finally,we conduct experiments on the open source real DNS traffic dataset provided by QI-ANXIN Technology Group to evaluate the PUMD framework's abil-ity to capture potential command and control(C&C)domains for malicious activities.The experimental results prove that PUMD can achieve the best detection performance under different label frequencies and class imbalance ratios.Zhaoshan Fan Qing Wang Haoran Jiao Junrong Liu Zelin Cui Song Liu Yuling Liu 2023Cybersecurity2023,6,1:0
17Accelerating net-zero carbon emissions by electrochemical reduction of carbon dioxide显示文摘Electroreduction of CO_(2)shows great potential for global CO_(2)utilization and uptake when collaborated with renewable electricity.Recent advances have been achieved in fundamental understanding and electrocatalyst development for CO_(2)electroreduction.We think this research area has progressed to the stage where significant efforts can focus on translating the obtained knowledge to the development of largescale electrolyzers,which have the potential to accelerate the transition of the current energy system into a sustainable and zero-carbon emission energy structure.In this perspective paper,we first critically evaluate the advancement of vapor-feed devices that use CO_(2)as reactants,from the point of view of industry applications.Then,by carefully comparing their performance to the state-of-the-art water electrolyzers which are well-established technology providing realistic performance targets,we looped back and discussed the remaining challenges including electrode catalysts,reaction conditions,mass transporting,membrane,device durability,operation mode,and so on.Finally,we provide perspectives on the challenges and suggest opportunities for generating fundamental knowledge and achieving technological progress toward the development of practical CO_(2)electrolyzers for the goal of building lowcarbon or/and net carbon-free economies.Fan He Sirui Tong Zhouyang Luo Haoran Ding Ziye Cheng Chenxi Li Zhifu Qi 2023Journal of Energy Chemistry2023,,4:0
18TSCND:Temporal Subsequence-Based Convolutional Network with Difference for Time Series Forecasting显示文摘Time series forecasting plays an important role in various fields, such as energy, finance, transport, and weather. Temporal convolutional networks (TCNs) based on dilated causal convolution have been widely used in time series forecasting. However, two problems weaken the performance of TCNs. One is that in dilated casual convolution, causal convolution leads to the receptive fields of outputs being concentrated in the earlier part of the input sequence, whereas the recent input information will be severely lost. The other is that the distribution shift problem in time series has not been adequately solved. To address the first problem, we propose a subsequence-based dilated convolution method (SDC). By using multiple convolutional filters to convolve elements of neighboring subsequences, the method extracts temporal features from a growing receptive field via a growing subsequence rather than a single element. Ultimately, the receptive field of each output element can cover the whole input sequence. To address the second problem, we propose a difference and compensation method (DCM). The method reduces the discrepancies between and within the input sequences by difference operations and then compensates the outputs for the information lost due to difference operations. Based on SDC and DCM, we further construct a temporal subsequence-based convolutional network with difference (TSCND) for time series forecasting. The experimental results show that TSCND can reduce prediction mean squared error by 7.3% and save runtime, compared with state-of-the-art models and vanilla TCN.Haoran Huang Weiting Chen Zheming Fan 2024Computers, Materials & Continua2024,78,3:0
19Tourmaline guiding the electric field and dechlorination pathway of 2,3-dichlorophenol by Desulfitobacterium hafniense显示文摘The dehalogenation of organohalides has been a research hotspot in bioremediation field;however,the influence of tourmaline,a natural ore that can generate spontaneous electric field,on organohalide-respiring bacteria(OHRB)and their dechlorination process is not well known.In this study,the effect and mechanism of tourmaline on the reductive dechlorination of 2,3-dichlorophenol(2,3-DCP)by Desulfitobacterium hafniense DCB-2Twere explored.The characterization results confirmed that tourmaline had good stability and the optimal dosage of tourmaline was 2.5 g/L,which shortened the total time required for dechlorination reaction to 72 hr.Besides,tourmaline amendment also increased the proportion of 2-chlorophenol(2-CP)from 18%to 30%of end products,while that of 3-CP decreased correspondingly.The theoretical calculations showed that the bond charge of the orthosubstituted chlorine declined from-0.179 to-0.067,and that of meta-substituted chlorine increased from-0.111 to-0.129,which indicated that the spontaneous electric field of tourmaline affected the charge distribution of 2,3-DCP and was more conducive to the generation of 2-CP.Overall,tourmaline with the spontaneous electric field affected the reductive dechlorination pathway of Desulfitobacterium,and the tourmaline-OHRB combining system might serve as a novel strategy for the bioremediation of environments polluted with chlorinated phenols.Yue Lu Fangyi Liang Fanzhi Qin Linrui Zhong Jianhong Jiang Qi Liu Shoujuan Zhang Ming Yan Changzheng Fan Haoran Dong 2024Journal of Environmental Sciences2024,,1:0
20Adaptive Fractional-Order PID Control for VSC-HVDC Systems via Cooperative Beetle Antennae Search with Offshore Wind Integration显示文摘Since the voltage source converter based high voltage direct current(VSC-HVDC)systems owns the features of nonlinearity,strong coupling and multivariable,the classical proportional integral(PI)control is hard to obtain content control effect.Hence,a new perturbation observer based fractional-order PID(PoFoPID)control strategy is designed in this paper for(VSC-HVDC)systems with offshore wind integration,which can efficiently boost the robustness and control performance of entire system.Particularly,it employs a fractional-order PID(FoPID)fra-mework for the sake of compensating the perturbation estimate,which dramatically boost the dynamical responds of the closed-loop system,and the cooperative beetle antennae search(CBAS)algorithm is adopted to quickly and effi-ciently search its best control parameters.Besides,CBAS algorithm is able to efficiently escape a local optimum because of a suitable trade-off between global exploration and local exploitation can be realized.At last,comprehensive case studies are carried out,namely,active and reactive power tracking,5-cycle line-line-line-ground(LLLG)fault,and offshore wind farm integration.Simulation results validate superiorities and effectiveness of PoFoPID control in com-parison of that of PID control and feedback linearization sliding-mode control(FLSMC),respectively.Pulin Cao Haoran Fan Zilong Cai 2021Energy Engineering2021,118,2:0
