Abstract

This application relates to an energy storage converter series compensation system and stability analysis method thereof, a damping controller, and an energy storage system, capable of acquiring a voltage signal of a capacitor disposed between an energy storage battery pack and a converter of the energy storage converter series compensation system, and determining, based on the voltage signal, whether an activation condition is satisfied. When the activation condition is satisfied, an adaptive adjustment filter is activated to enable the damping controller to participate in the operation of the energy storage converter series compensation system. A voltage synchronization controller determines, based on a sub-synchronous frequency band voltage signal output by the adaptive adjustment filter and an initial voltage signal, an output phase angle signal required for a pulse width modulation signal to control operation of the converter.
