Open AccessHigh Voltage Direct Current(HVDC) is widely considered as an efficient and economical option for long distances transmission of electric power compared to ac transmission. Conventional HVDC transmission is based on line ...
On the solution of equilibrium points of power systems with penetration of power electronics considering converter limitation Song, Jie; Cheah Mañé, Marc; Prieto Araujo, Eduardo; Gomis Bellmunt, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2022-01-01)
Open AccessThis article presents a novel approach for black-box modeling of 270 V-to-28 V dc–dc step-down converters used in more electric aircrafts. These converters normally feed constant power loads. The proposed deep learning ...
Steady-state impedance mapping in grids with power electronics: What is grid strength in modern power systems? Gomis Bellmunt, Oriol; Song, Jie; Cheah Mañé, Marc; Prieto Araujo, Eduardo (2022-03-01)
Open AccessThe paper analyzes grid strength and grid impedance for systems with significant penetration of power electronics. The work shows that the traditionally employed Thévenin equivalent cannot capture the different saturation ...
