What is the frequency modulation of hybrid energy storage?

Under the four control strategies of A, B, C and D, the hybrid energy storage participating in the primary frequency modulation of the unit |Δ fm | is 0.00194 p.u.Hz, excluding the energy storage system when the frequency modulation |Δ fm | is 0.00316 p.u.Hz, compared to a decrease of 37.61 %.

How to evaluate frequency modulation performance under a control strategy?

Similarly, under external perturbations, the frequency modulation power change evaluation method is similar to frequency, the corresponding average value of power fluctuation is adopted Pm, power peak difference Δ P, the overall degree of power fluctuation Psd evaluates the frequency modulation performance under the corresponding control strategy.
