Battery energy storage systems (BESS) with power electronic devices as an interface are well suitable for accelerating fault recovery in short-term power due to their flexible inputs.
Therefore, the overall system frequency f g is stabilized by the energy stored in rotational system elements (SGs) in case of an imbalance between power generation and load Δ P Imbalance (Bevrani et al., 2014, D’Arco et al., 2015).
Battery energy storage systems (BESS) offer rapid response capabilities, making them a favorable choice for enhancing power system stability. However, a wide variety of battery types are available, requiring careful selection based on specific applications.
It is further remarkable that the power system frequency does not return to the normal range, although the possible converter power of the battery is equal to the total load that has been changed in L800: 33 M VA . Moreover, the peak power of the converter becomes smaller, making it impossible to achieve a total power equal to the load power.
