Aiming at when there is an imbalance in the grid voltage, which will cause the problem of the energy storage system output active power fluctuation even caused the failure condition, this research presents a fault ride-through control strategy of the active reactive power fluctuation suppression based on the instantaneous power theory and weighted thoughts. This paper's recommended control strategy does not require phase-locking of the grid voltage, and it also does not need to separate control of the positive and negative sequence currents, co...
