Research on a risk evaluation and suppression method for high-frequency resonance of flexible low-frequency transmission

open access: yesZhejiang dianli, 2022
Due to the long delay of their control chains, voltage source converters (VSCs) in the high frequency band tend to show negative damping, which may give rise to high-frequency resonance when VSCs are connected to power systems.

Suppression of synchronous resonance for VSGs [PDF]

open access: yesThe Journal of Engineering, 2017
The virtual synchronous generator (VSG) is an attractive interfacing technique for high-penetration renewable generation. By incorporating the inertia control, the grid-connected voltage-source converter can behave in a similar way with the SGs, which is helpful to enhance the stability of the power system.

Suppressing subsynchronous resonance with static filters

open access: yesIEE Proceedings C Generation, Transmission and Distribution, 1981
The design, mode of operation and limitations of static-subsynchronous-resonance (SSR) suppression filters are described. The effectiveness of these filters is evaluated by eigenvalue analyses using linearized mathematical models and transient simulations.

Ultracold three-body collisions near narrow Feshbach resonances [PDF]

open access: yes, 2010
We study ultracold three-body collisions of bosons and fermions when the interatomic interaction is tuned near a narrow Feshbach resonance. We show that the width of the resonance has a substantial impact on the collisional properties of ultracold gases ...

Dynamic Resonance Analysis and Oscillation Damping of Multiterminal DC Grids

open access: yesIEEE Access, 2017
Voltage-source converter-based multiterminal high-voltage direct current (VSC-MTDC) systems/grids are prone to system instability. This critical issue is overlooked in the literature. In order to improve system stability, this paper proposes an effective
