| 2 | China’s hydropower energy system toward carbon neutrality显示文摘Wind and solar powers will gradually become dominant energies toward carbon neutrality.Large-scale renewable energies,with strong stochasticity,high volatility,and unadjustable features,have great impacts on the safe operation of power system.Thus,an advanced hydropower energy system serving multiple energies is required to respond to volatility,with expanding role from a“stable energy supplier”to a“flexible efficiency regulator”.Future research and application can be considered from three aspects:1)system expansion(e.g.,the construction of large-scale hydropower/renewable energy bases in China,the construction of transnational hydropower energy internet,and the functional transformation of traditional hydropower reservoirs and generating units);2)efficiency promotion(e.g.,advanced intelligent forecasting,multi-objective operation,and risk management methods);and 3)supporting measures(e.g.,market reform,benefit compensation and policy mechanism,technical standards,and laws and regulations). | Zhongkai FENG Wenjing NIU Chuntian CHENG Jianzhong ZHOU Tao YANG | 2022 | Frontiers of Engineering Management2022，9，4： | 1 |
| 3 | Dimensionality-driven metal to Mott insulator transition in two-dimensional 1T-TaSe_(2)显示文摘Two-dimensional materials represent a major frontier for research into exotic many-body quantum phenomena.In the extreme two-dimensional limit,electron-electron interaction often dominates over other electronic energy scales,leading to strongly correlated effects such as quantum spin liquid and unconventional superconductivity.The dominance is conventionally attributed to the lack of electron screening in the third dimension.Here,we discover an intriguing metal to Mott insulator transition in 1T-TaSe_(2) that defies conventional wisdom.Specifically,we find that dimensionality crossover,instead of reduced screening,drives the transition in atomically thin 1T-TaSe_(2).A dispersive band crossing the Fermi level is found to be responsible for the bulk metallicity in the material.Reducing the dimensionality,however,effectively quenches the kinetic energy of these initially itinerant electrons,and drives the material into aMott insulating state.The dimensionality-driven metal to Mott insulator transition resolves the long-standing dichotomy between metallic bulk and insulating surface of 1T-TaSe_(2).Our work further reveals a new pathway for modulating two-dimensional materials that enables exploring strongly correlated systems across uncharted parameter space. | Ning Tian Zhe Huang Bo Gyu Jang Shuaifei Guo Ya-Jun Yan Jingjing Gao Yijun Yu Jinwoong Hwang Cenyao Tang Meixiao Wang Xuan Luo Yu Ping Sun Zhongkai Liu Dong-Lai Feng Xianhui Chen Sung-Kwan Mo Minjae Kim Young-Woo Son Dawei Shen Wei Ruan Yuanbo Zhang | 2024 | National Science Review2024，11，3： | 0 |
| 4 | A 16-parameter GEO Broadcast Ephemeris显示文摘Currently,the broadcast ephemerides used in GEOs are same as those of the MEOs and IGSOs in the BeiDou navigation constellation.However,a trade-off strategy,i.e.an orbital inclination of 5°rotation,is needed in the fitting algorithm to solve the ephemeris parameters as well as the user satellite position computation for GEOs.Based on the standard broadcast ephemerides,the representations of both the orbit and its perturbation were revised according to the second class of nonsingular orbital elements.In this research,a 16-parameter broadcast ephemeris is presented specifically for GEOs,and user satellite position computation formulas were derived correspondingly.Fit simulations show that the root of mean squares(RMS)of user range error(URE)with two hour and three hour data sets are better than 0.05 m and 0.1 m,respectively. | Zhongkai ZHANG Lan DU Li LIU Feng HE Yu LU Peiyuan ZHOU | 2018 | Journal of Geodesy and Geoinformation Science2018，1，1： | 0 |
