Properties and Physical Interpretation of the Dynamic Interactions between Voltage Source Converters and Grid: Electrical Oscillation and Its Stability Control
Zhang, Chen; Molinas Cabrera, Maria Marta; Rygg, Atle; Li, Zheng; Cai, Xu (Journal article; Peer reviewed, 2017)Voltage source converters (VSCs) play an important role in the power conversion of renewable power generation (RPG) systems. Conventional power systems are considerably affected by power electronic devices in systems with ... -
Resilient cooling of buildings to protect against heat waves and power outages: Key concepts and definition
Attia, Shady; Levinson, Ronnen; Ndongo, Eileen; Holzer, Peter; Kazanci, Ongun; Homaei, Shabnam; Zhang, Chen; Olesen, Bjarne W.; Qi, Dahai; Hamdy, Mohamed; Heiselberg, Per (Peer reviewed; Journal article, 2021)The concept of climate resilience has gained extensive international attention during the last few years and is now seen as the future target for building cooling design. However, before being fully implemented in building ... -
Sequence Domain SISO Equivalent Models of a Grid-tied Voltage Source Converter System for Small-Signal Stability Analysis
Zhang, Chen; Molinas Cabrera, Maria Marta; Rygg, Atle; Cai, Xu (Journal article; Peer reviewed, 2017)This paper presents a generalized method for converting multi-input and multi-output (MIMO) dq impedance model of a grid-tied voltage source converter system into its sequence domain single-input and single-output (SISO) ... -
Synchronizing Stability Analysis and Region of Attraction Estimation of Grid-Feeding VSCs Using Sum-of-Squares Programming
Zhang, Chen; Molinas Cabrera, Maria Marta; Zheng, Li; Cai, Xu (Peer reviewed; Journal article, 2020)Grid-synchronizing Stability (GSS) is an emerging issue related to grid-feeding voltage-source converters (VSCs). Its occurrence is primarily related to the non-linear dynamics of a type of vastly applied synchronization ... -
Understanding the Nonlinear Behaviour and Synchronizing Stability of a Grid-Tied VSC Under Grid Voltage Sags
Zhang, Chen; Molinas Cabrera, Maria Marta; Lyu, Jing; Zong, Haoxiang; Cai, Xu (Chapter, 2019)Transients of a typical grid synchronizing VSC are closely associated with the over-current and over-voltage in circuits. Previous analysis in evaluating such transient phenomenon usually ignore the nonlinear control effects ...
