Patent number: 11983472Abstract: Disclosed is a method for identifying fragile lines in power grid based on electrical betweenness, which comprises the following steps: constructing the power grid into a network diagram, sequentially removing lines in the network diagram, and sorting the electrical betweenness of each line from large to small; constructing a nonlinear model of complex network cascade failure considering overload and weighted edges, and respectively performing two ways of removing lines for sorted electrical betweenness, namely sequentially removing preset proportion lines and sequentially removing all lines until no new lines are removed in the network diagram; obtaining a change of generator-load power before and after each line removal, and evaluating a severity of power grid failure based on the change of generator-load power, thus completing an identification of power grid fragile lines.Type: GrantFiled: March 28, 2023Date of Patent: May 14, 2024Assignee: HUNAN UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Chaoyang Chen, Yong Zhou, Zuguo Chen, Li He, Zhuangxi Tan, Pei Li, Ying Zou, Xiaowen Wu

Publication number: 20230111862Abstract: The present disclosure relates to wood template-supported phase change material (PCM) composites having thermal energy storage applications. A wood template-supported PCM composite may include a wood template that has had at least a portion of its xylan and/or lignin removed and saturated with a PCM. The PCM may be stabilized with a cross linkable network for improved infiltration into the wood template. The wood template-supported PCM composite may be formed by extracting xylan and/or lignin from the wood to create a wood template, densifying at least a portion of the wood template, and inserting a PCM into the wood template.Type: ApplicationFiled: September 30, 2022Publication date: April 13, 2023Inventors: Shuang CUI, Charles William BOOTEN, Judith Cecilia VIDAL, Yudong LI, Kyle Edward O'Neil FOSTER, Xiaowen CHEN, Kelsey Mary LYNCH, Hongbing LU, Bernadette Karen MAGALINDAN, Gustavo Felicio PERRUCI
