In practice, the frequency fluctuation of a unit is generally caused by continuous and irregular load fluctuations, therefore, simulate the impact of coupling a hybrid energy storage system and a single energy storage system on the primary frequency regulation of thermal power units under continuous disturbances.
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.
