An improved active damping control in grid-connected converter system
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017Grid-connected converters have been widely used in distributed generations. However, the resonance brought by converters in weak grid has been a great threat to system stability. Impedance-based method provides a powerful tool for stability analysis. Active damping is also widely applied to improve system stability.
