| 1 | Dynamical economic dispatch using distributed barrier function-based optimization algorithm显示文摘In this paper, we study the distributed economic dispatch problem where the supply demand balance, capacity constraints and ramp-rate constraints are considered. In order to accommodate varying power load and power storage in reality, we introduce two variables where each variable is time-varing and has its own dynamics. The renewable power is also considered. Barrier functions are introduced to deal with the local constraints by means of imposing penalty terms into the objective function to ensure that the optimal solution satisfies the corresponding constraints. Based on the Langrange dual theory, the primal optimization problem is transformed into the dual problem, which is solved by the primary-dual algorithm proposed in this paper. Under the assumption that the communication graph is an undirected and connected graph, we analyze the convergence of the proposed algorithm. The simulations on IEEE six-bus test systems are carried out to verify the performance of the algorithm, which shows that the proposed algorithm converges to the optimal solution, while all the constraints are met. | YAO YiYang TIAN FangZheng MEI Feng FU JunJie DAI Bo YU WenWu | 2019 | Science China(Technological Sciences)2019，62，12： | 2 |
| 2 | A distributed normalized Nash equilibrium seeking algorithm for power allocation among micro-grids显示文摘In this paper, a power allocation problem based on the Cournot game and generalized Nash game is proposed. After integrating dynamic average consensus algorithm and distributed projection neural network through singular perturbation systems, a normalized Nash equilibrium seeking algorithm is presented to solve the proposed power allocation problem in a distributed way.Combine Lyapunov stability with the singular perturbation analysis, the convergence of the proposed algorithm is analyzed. A simulation on IEEE 118-bus confirms that the proposed distributed algorithm can adjust the power allocation according to different situations, while keeping the optimal solution within the feasible set. | FU Zao YU WenWu LU JinHu YAO YiYang MEI Feng | 2021 | Science China(Technological Sciences)2021，64，2： | 1 |

| 5 | Cycle temporal algorithm-based multivariate statistical methods for fault diagnosis in chemical processes显示文摘Multivariate statistical process monitoring methods are often used in chemical process fault diagnosis.In this article,(I)the cycle temporal algorithm(CTA)combined with the dynamic kernel principal component analysis(DKPCA)and the multiway dynamic kernel principal component analysis(MDKPCA)fault detection algorithms are proposed,which are used for continuous and batch process fault detections,respectively.In addition,(II)a fault variable identification model based on reconstructed-based contribution(RBC)model that paves the way for determining the cause of the fault are proposed.The proposed fault diagnosis model was applied to Tennessee Eastman(TE)process and penicillin fermentation process for fault diagnosis.And compare with other fault diagnosis methods.The results show that the proposed method has better detection effects than other methods.Finally,the reconstruction-based contribution(RBC)model method is used to accurately locate the root cause of the fault and determine the fault path. | Jiaxin Zhang Wenjia Luo Yiyang Dai Yuman Yao | 2022 | Chinese Journal of Chemical Engineering2022，35，7： | 0 |
| 6 | Role of intrinsic defects on carbon adsorbent for enhanced removal of Hg^(2+)in aqueous solution显示文摘Carbon is a normally used adsorbent for removal of heavy metal ion in aqueous solutions,but the efficient adsorbent needs intensive modification by heteroatom doped or supported noble metals that cause severe pollution and easy leaching of active components during use.In this paper,the role of intrinsic defects on Hg^(2+)adsorption for carbon adsorbent was investigated.The maximum adsorbing capacity of defectrich carbon has been improved up to 433 mg·g^(-1)which is comparable to most of the modified carbon adsorbents via supported metal chloride or noble metal components.The basicity is increased with the content of defective sites and the strong chemical bonding can be formed via electron transformation between the defect sites with adsorbed Hg^(2+).The present study gives a direction to explore cheap and easily scale-up high-performance mercury adsorbents by simply tuning the intrinsic defective structure of carbon without the necessity to support metal or other organic compounds. | Liu He Yiyang Qiu Chu Yao Guojun Lan Na Li Huacong Zhou Quansheng Liu Xiucheng Sun Zaizhe Cheng Ying Li | 2023 | Chinese Journal of Chemical Engineering2023，61，9： | 0 |
| 7 | Regulating local charges of atomically dispersed Moδ+ sites by nitrogen coordination on cobalt nanosheets to trigger water dissociation for boosted hydrogen evolution in alkaline media显示文摘Now,Pt-based materials are still the best catalysts for hydrogen evolution reaction(HER).Nevertheless,the scarcity of Pt makes it impossible for the large-scale applications in industry.Although cobalt is taken as an excellent HER catalyst due to its suitable H*binding,its alkali HER catalytic property need to be improved because of the sluggish water dissociation kinetics.In this work,nitrogen with small atomic radius and metallophilicity is employed to adjust local charges of atomically dispersed Mo^(δ+)sites on Co nanosheets to trigger water dissociation.Theoretical calculations suggest that the energy barrier of water dissociation can be effectively reduced by introducing nitrogen coordinated Mo^(δ+)sites.To realize this speculation,atomically dispersed Mo^(δ+)sites with nitrogen coordination of Mo(N)/Co were prepared via reconstruction of CoMoO_(4).High angle annular dark-field scanning transmission electron microscopy(HAADF-STEM)and X-ray absorption spectroscopy(XAS)demonstrate the coordination of N atoms with atomically dispersed Mo atoms,leading to the local charges of atomically dispersed Mo^(δ+)sites in Mo(N)/Co.The measurement from ambient pressure X-ray photoelectron spectroscopy(AP-XPS)reveals that the Mo^(δ+)sites promote the adsorption and activation of water molecule.Therefore,the Mo(N)/Co exhibits an excellent activity,which need only an overpotential of 39 mV to reach the current density of 10 mA cm^(-2).The proposed strategy provides an advance pathway to design and boost alkaline HER activity at the atomic-level. | Maoqi Cao Kang Liu Yao Song Chao Ma Yiyang Lin Huangjingwei Li Kejun Chen Junwei Fu Hongmei Li Jun Luo Yida Zhang Xusheng Zheng Junhua Hu Min Liu | 2022 | Journal of Energy Chemistry2022，31，9： | 0 |
| 8 | High-resolution aging niche of human adipose tissues显示文摘Dear Editor,Age-dependent adipose tissue malfunction raises the risk of diseases like diabetes,cardiovascular disease,and even cancer by contributing to metabolic decline,heterotopic fat storage,and chronic systemic inflammation.1 Understanding adipose tissue aging requires in-depth knowledge of the cellular and molecular properties of various adipose tissue cell types.Although the heterogeneity of the cell population during mouse aging has been studied,2 little is known about the cellular and molecular basis of human adipose tissues aging. | Wenyan Zhou Junxin Lin Yan Xie Xueqing Hu Xudong Yao Yuemin Ou Hongwei Wu Yiyang Yan Xiumao Li Jianan Lou Aaron Trent Irving James Q.Wang Hongwei Ouyang | 2023 | Signal Transduction and Targeted Therapy2023，8，4： | 0 |
