Active Damping for Dynamic Improvement of Multiple Grid-Tied Virtual Synchronous Generators

open access: yesIEEE transactions on industrial electronics (1982. Print)
To eliminate low-frequency oscillations, this article proposes an active-damping method for multiple grid-tied virtual synchronous generators (VSGs) in a power plant. First, using Lyapunov’s indirect method, the damping ratio of multiple VSGs in parallel

Stability analysis and parameter configuration of parallel virtual synchronous generators in microgrid

open access: yesEnergy Reports, 2022
The current small-signal stability analysis and parameter selection of converters that mimic synchronous generators usually ignore some dynamic characteristics and the changes of steady-state operating points for simplicity. It could only judge the trend
