| 1 | Effect of Al_(2)O_(3)/CaO on the melting and mineral transformation of Ningdong coal ash显示文摘Coal ash melting characteristics has a direct impact on the smooth operation of entrained gasifier.Mineral conversion of coal ash is very significant to be investigated,because the mineral can affect the melting temperature and viscosity under high temperature conditions.In this paper,the effects of different Al2O3/CaO on the mineral conversion,melting temperature and viscosity of Ningdong coal ash are studied by the combination of experiment and simulation.The trend of melting temperature decreases firstly and rises with increasing Al_(2)O_(3)/CaO.The ashmelting point reached to the lowestwhen the ratio is 1.23.XRD and Factsage software are used to analyze crystallization behavior of samples.The results showthat the content of anorthite,albite and corundumincreases and subsequently decreases,while the content of mullite decreases firstly and then rises with increasing Al_(2)O_(3)/CaO.High content with CaO can contribute to form albite and anorthite of low-melting.Besides,high content with Al_(2)O_(3) can tend to produce mullite of high-melting.The results of experimental and simulation are basically the same,which lays a foundation for the melting characteristics of Ningdong coal ash and can provide technical support for the smooth operation of the entrained-gasifier. | Feng Wang Min Yao Haoyong Kan Jianping Kuang Ping Li Jiashuo Zhang Yixin Zhang | 2020 | Chinese Journal of Chemical Engineering2020，28，12： | 3 |
| 2 | Bi-level optimization based two-stage market clearing model considering guaranteed accommodation of renewable energy generation显示文摘The existing electricity market mechanisms designed to promote the consumption of renewable energy generation complicate network participation in market transactions owing to an unfair market competition environment,where the low cost renewable energy generation is not reflected in the high bidding price of high cost conventional energy generation.This study addresses this issue by proposing a bi-level optimization based two-stage market clearing model that considers the bidding strategies of market players,and guarantees the accommodation of renewable energy generation.The first stage implements a dual-market clearing mechanism that includes a unified market for trading the power generations of both renewable energy and conventional energy units,and a subsidy market reserved exclusively for conventional generation units.A re-adjustment clearing mechanism is then proposed in the second stage to accommodate the power generation of remaining renewable energy units after first stage energy allocations.Each stage of the proposed model is further described as a bi-level market equilibrium problem and is solved using a co-evolutionary algorithm.Finally,numerical results involving an improved IEEE 39-bus system dem-onstrate that the proposed two-stage model meets the basic requirements of incentive compatibility and individual rationality.It can facilitate the rational allocation of resources,promote the economical operation of electric power grids,and enhance social welfare. | Qianya He Zhenjia Lin Haoyong Chen Xinyun Dai Yirui Li Xin Zeng | 2022 | Protection and Control of Modern Power Systems2022，7，1： | 2 |
| 3 | Distributed sensing and cooperative estimation/detection of ubiquitous power internet of things显示文摘The rapid development of Internet Plus Smart Energy requires further strengthening of three kinds of interconnections based on traditional power systems: physical interconnection, information interconnection, and commercial interconnection. Due to the integration of renewable energy, the reform of the electricity market, and the deployment of the Smart Grid, a large amount of data will be generated. Thus, it is necessary to establish a Ubiquitous Power Internet of Things (UPIoT) to realize connections among people and things, things and things, and people and people in power systems. This paper studies the concept and architecture of the UPIoT and indicates the deployment of the perception layer and network layer as the key to building UPIoT in the initial stage. As UPIoT tends to cover a wide area and produce massive and distributed data, signal processing and data analytics theories and techniques are needed to handle the data and observe the state of the large-scale system. Further studies on distributed sensing and cooperative estimation theories and techniques of UPIoT are also required. Finally, the application prospects of UPIoT and the directions for future research are discussed. | Haoyong Chen Xiaojuan Wang Zhihao Li Wutao Chen Yongzhi Cai | 2019 | Protection and Control of Modern Power Systems2019，4，1： | 2 |
| 4 | A Novel Tele-Operated Flexible Robot Targeted for Minimally Invasive Robotic Surgery显示文摘In this paper, a novel flexible robot system with a constrained tendon-driven serpentine manipulator(CTSM) is presented. The CTSM gives the robot a larger workspace, more dexterous manipulation, and controllable stiffness compared with the da Vinci surgical robot and traditional flexible robots. The robot is tele-operated using the Novint Falcon haptic device. Two control modes are implemented, direct mapping and incremental mode. In each mode, the robot can be manipulated using either the highest stiffness scheme or the minimal movement scheme. The advantages of the CTSM are shown by simulation and experimental results. | Zheng Li Jan Feiling Hongliang Ren Haoyong Yu | 2015 | Engineering2015，1，1： | 2 |
| 5 | Methane in soil gas and its transfer to the atmosphere in the Yakela condensed gas field in the Tarim Basin,Northwest China显示文摘In this study,by analyzing CH4 concentration and δ13CCH4 in soil-gas profiles,the potentials of CH4 gas transfer from ground to atmosphere were studied at four representative sectors in the Yakela condensed gas field in the Tarim Basin,Xinjiang,China.These are:1) the oil-gas interface sector,2) fault sector,3) oil-water interface sector,4) an external area.Variation in CH4 in soil-gas profiles showed that CH4 microseepage resulted from the migration of subsurface hydrocarbon from deep-buried reservoirs to the earth's surface.It was found that CH4 from deep-buried reservoirs could migrate upwards to the surface through faults,fissures and permeable rocks,during which some CH4 was oxidized and the unoxidized methane remained in the soil or was emitted into the atmosphere.The lowest level of CH4 at the soil-gas profile was found at the CH4 gas-phase equilibrium point at which the CH4 migration upwards from deep-buried reservoirs and the CH4 diffusion downwards from the atmosphere met.The δ13CCH4 and ethane,propane in soil gas exhibited thermogenic characteristics,suggesting the occurrence of CH4 microseepage from deep-buried reservoirs.A linear correlation analysis between CH4 concentrations in soil gas and temperature,moisture,pH,Eh,Ec and particle size of soil indicated that both soil Eh and soil temperature could affect CH4 concentration in soil gas while soil pH could indirectly influence soil methanotrophic oxidation via impacting soil Eh. | Tang Junhong Wang Guojian Yin Haoyong Li Hongjun | 2013 | Petroleum Science2013，10，2： | 2 |

| 9 | A Mixed-integer SDP Solution to Distributionally Robust Unit Commitment with Second Order Moment Constraints显示文摘A power system unit commitment(UC)problem considering uncertainties of renewable energy sources is investigated in this paper,through a distributionally robust optimization approach.We assume that the first and second order moments of stochastic parameters can be inferred from historical data,and then employed to model the set of probability distributions.The resulting problem is a two-stage distributionally robust unit commitment with second order moment constraints,and it can be recast as a mixed-integer semidefinite programming(MI-SDP)with finite constraints.The solution algorithm of the problem comprises solving a series of relaxed MI-SDPs and a subroutine of feasibility checking and vertex generation.Based on the verification of strong duality of the semidefinite programming(SDP)problems,we propose a cutting plane algorithm for solving the MI-SDPs;we also introduce an SDP relaxation for the feasibility checking problem,which is an intractable biconvex optimization.Experimental results on the IEEE 6-bus system are presented,showing that without any tuning of parameters,the real-time operation cost of distributionally robust UC method outperforms those of deterministic UC and two-stage robust UC methods in general,and our method also enjoys higher reliability of dispatch operation. | Xiaodong Zheng Haoyong Chen Yan Xu Zhengmao Li Zhenjia Lin Zipeng Liang | 2020 | CSEE Journal of Power and Energy Systems2020，6，2： | 1 |

| 13 | Investigation of the Heterogeneous Nucleation on Fractal Surfaces显示文摘Classical theory of heterogeneous nucleation has been developed with an implied hypothesis of smooth substrate surfaces; however, morphologies of any real substrate surfaces are generally complicated and demonstrate fractal characteristics. In this paper, the wettability between the embryo and the fractal substrate surface was discussed, and heterogeneous nucleation behaviors were theoretically analyzed. The result shows that the roughness factor of a fractal surface varies with the scale of the embryo. As a result, the fractal character of the substrate surface has important effects on heterogeneous nucleation behaviors. It has been shown that the energy barrier for heterogeneous nucleation of a non-wetting phase on a fractal rough surface increases with increasing fractal dimensions, and both the critical nucleus radius and the nucleation energy barrier decrease with increasing fractal dimensions for heterogeneous nucleation of a wetting phase on the fractal rough surface. For a non-wetting system, the critical nucleus radius shows a slight shift with changes of the intrinsic wetting angle, but for a wetting system, the critical nucleus radius shows an obvious change with decreasing intrinsic wetting angle, thus imposes a stronger effect on the heterogeneous nucleation behaviors. | Meng Wang Ying Zhang Haoyong Zheng Xin Lin Weidong Huang | 2012 | Journal of Materials Science & Technology2012，28，12： | 1 |
