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 power systems, frequency is the continuously changing variable which is influenced by the power generation and demand. A generation deficit results in frequency reduction while surplus generation causes an increase in the frequency. The frequency is kept in permissible limits for the stable operation of power systems.
Power systems maintain frequency within the limits defined by grid codes by dynamically matching the generation and demand for secure operation. Large frequency excursions cause the tripping of loads and generators, which may lead to system collapse [, , , ].
Frequency regulation in power system In power systems, frequency is the continuously changing variable which is influenced by the power generation and demand. A generation deficit results in frequency reduction while surplus generation causes an increase in the frequency.
