HE inherent variability and increasing penetration of Renewable Energy Sources (RESs) in power systems have the potential to negatively impact the system frequency. Fast power response Energy Storage System (ESS) technolo- gies can mitigate frequency variations when included in the Frequency Regulation (FR) control loop .
Dynamic frequency support requires continuous charging/discharging which involves partial charge/discharge events (detrimental to BES life). In addition, the required energy capacity can also be higher depending on the type of system. Thus, for dynamic frequency support hybrid storage is more suitable. 7. Research gaps and future directions
In modern power system, the frequency regulation (FR) has become one of the most crucial challenges compared to conventional system because the inertia is reduced and both generation and demand are stochastic.
The fast responsive energy storage technologies, i.e., battery energy storage, supercapacitor storage technology, flywheel energy storage, and superconducting magnetic energy storage are recognized as viable sources to provide FR in power system with high penetration of RES.
The notable work has sized the faster storage technology for IR while slower one for PFR service. In hybrid energy storage, both the sizing and operation are challenging tasks compared to single storage technology. As the hybrid storage system deploy more than one storage technologies, the sizing becomes more complicated.
Moreover, the SoC of the BES is re-established at a moderate rate of current when the frequency returns within the allowable limit. A similar rule based strategy, that dynamically adjusts the SoC limits, for the operation of BES providing FR in an isolated power system is proposed in Ref. .
