Current research on energy storage control strategies primarily focuses on whether energy storage systems participate in frequency regulation independently or in coordination with wind farms and photovoltaic power plants .
To address these challenges, energy storage systems can be controlled to emulate the inertial response of synchronous generators by providing virtual inertia, thereby enhancing the frequency stability of power systems . This approach has been widely recognized and adopted in modern low-inertia power systems.
The hybrid energy storage system combined with coal fired thermal power plant in order to support frequency regulation project integrates the advantages of “fast charging and discharging” of flywheel battery and “robustness” of lithium battery, which not only expands the total system capacity, but also improves the battery durability.
Traditionally, the regulation of grid frequency is achieved via the rotor dynamics of synchronous generators, with mechanical inertia and damping properties influencing the system's dynamic frequency behavior, following the swing equation.
