A Multi-stage Resilience Enhancement Strategy for Distribution Networks Considering Disaster Uncertainties and Scheduling Non-anticipativity

引用

Dianwang Jishu/Power System Technology 2025年第1期49卷 146-156页

作者： ding, Zhilong Zhang, yachao School of Electrical Engineering and Automation Fuzhou University Fujian Province Fuzhou 350108 China

In recent years, typhoons and rainstorms have increasingly become the typical natural disasters that affect the safe and stable operation of distribution networks in coastal cities. To effectively cope with the influence of extreme disasters, a multi-stage resilience enhancement strategy is proposed for distribution networks, considering the spatiotemporal uncertainty of typhoon rainstorm disasters. Firstly, the disaster scenarios are simulated according to the historical data of typhoons, and the failure probability of distribution lines is calculated to construct an uncertainty set for the typhoon rainstorm disaster attack. On this basis, combined with the non-anticipativity characteristics of the power system scheduling process, a multi-stage robust optimization model based on the uncertainty set above is established. Secondly, a pre-extended robust dual dynamic programming algorithm is developed for solving. Then, the pre-disaster defense strategies and well-trained worst-case cost-to-go functions during disasters are obtained, which can solve the emergency response strategies for each period of extreme disasters. As a result, the optimal resilience enhancement strategies for distribution networks have been made in an organic combination of offline training and online application. Finally, the test systems for distribution networks with different scales are used to verify the effectiveness of the proposed model and method. © 2025 Power System Technology Press.

Late Paleozoic–Early Mesozoic tectonic evolution of the Zongwulong Shan-Qinghai nanshan tectonic belt in the northern Qaidam continent， northern Tibet

引用

Journal of Earth Science 2025年

作者： Yonghui Zhao Chen Wu Jie Li Peter J.Haproff Lin ding State Key Laboratory of Tibetan Plateau Earth System and Resources Environment (TPESRE)， Institute of Tibetan Plateau Research， Chinese Academy of Sciences University of Chinese Academy of Sciences Chongqing Key Laboratory of Complex Oil and Gas Field Exploration and Development， Chongqing University of Science and Technology Department of Earth and Ocean Sciences， University of North Carolina Wilmington

The Zongwulong Shan-Qinghai nanshan tectonic belt of the northern Tibet Plateau experienced a protracted tectonic history， including the openings and closures of the Proto- and Paleo-Tethyan Oceans. Although the tectonic belt has been extensively studied， details regarding the tectonic processes involved in its development remain controversial. To better constrain the tectonic processes of this tectonic belt， we conducted detailed field geological mapping， zircon U-Pb geochronology， and whole-rock geochemical and Sr-Nd isotopic analyses. Our results show that intrusive rocks in the tectonic belt crystallized in ca. 292–233 Ma， perhaps in an arc/subduction setting. Geochemical and Sr-Nd isotopic data suggest that early Permian–late Triassic ultramafic-intermediate intrusions were sourced from the enriched mantle， whereas intermediate-acidic rocks were sourced from mixed crust-mantle. We present the tectonic model that involves: (1) Early Devonian–early Permian intracontinental extension occurred in the northern margin of the Qaidam continent (ca. 416 Ma–292 Ma); (2) Early Permian–late Triassic northward subduction of the Paleo-Tethyan Ocean resulted in arc magmatism (ca. 292 Ma–233 Ma); and (3) subsequent late Triassic intracontinental extension (ca. 233 Ma–215 Ma). Our results suggest that the late Paleozoic–early Mesozoic development of the Zongwulong Shan-Qinghai nanshan was related to the opening， subduction， and slab retreat of the Paleo-Tethyan Ocean， which has key implications for the tectonic evolution of the northern Tibetan Plateau.

The direct-current simulation burning method was used to investigate the burn-resistant behavior of Ti14 titanium *** results show that Ti14 alloy exhibits a better burn resistance than TC4 alloy（Ti-6A1-4V）.Cu is observed to preferentially migrate to the surface of Ti14 alloy during the burning reaction,and the burned product contains Cu,Cu2O,and *** oxide layer mainly comprising loose TiO2 is observed beneath the burned ***,Ti2Cu precipitates at grain boundaries near the interface of the oxide layer,preventing the contact between O2 and Ti and forming a rapid diffusion layer near the matrix ***,a multiple-layer structure with a Cu-enriched layer（burned product）/Cu-lean layer（oxide layer）/Cu-enriched layer（rapid diffusion layer） configuration is formed in the burn heat-affected zone of Ti14 alloy;this multiple-layer structure is beneficial for preventing O2 ***,although A1 can migrate to form A12O3 on the surface of TC4 alloy,the burn-resistant ability of TC4 is unimproved because the Al2O3 is discontinuous and not present in sufficient quantity.

Modeling and control of a rigid-flexible coupling robot for narrow space manipulations

引用

Science China Technological Sciences 2025年

作者： Kuangda CHEN Huan ZHAO Jiexin ZHANG Mei FENG Yiwei WANG Jinliang WANG Han ding State Key Laboratory of Intelligent Manufacturing Equipment and Technology Huazhong University of Science and Technology Key Laboratory of CNC Equipment Reliability Ministry of Education Jilin University School of Medical Equipment Science and Engineering Huazhong University of Science and Technology

Narrow space manipulations are crucial for equipment maintenance, as they eliminate the need for disassembly, thus reducing costs and increasing efficiency. Cable-driven flexible robots possess exceptional capabilities in maneuvering through narrow spaces, thanks to their interaction compliance and distal dexterity. However, their inherent low stiffness causes a decline in the location accuracy of the robot and could even lead to manipulation failure. To address this challenge, this paper proposes a novel type of rigid-flexible coupling robot, which increases the stiffness of the robot while ensuring the reachability within a narrow space. To achieve high-accuracy location in a narrow space, kinematic and control methods are proposed. Specifically,the robot forward kinematics are uniformly represented, and the closed-form inverse kinematics solution is derived. Furthermore, in cases where the robot?s structure fails to align with Pieper?s solution, a two-stage search strategy is utilized to solve the inverse kinematics, resulting in a high success rate of 99.1%. Based on the proposed kinematics, a rigid-dominated control method is then proposed to facilitate localization and pose alignment of target objects in narrow spaces. The practical comparative experiments show that the proposed robot has the capability of high accuracy control in narrow spaces.
