The previous energy storage systems involved in secondary frequency modulation control strategy research mostly used the energy storage system as a small-capacity traditional frequency modulation unit for power signal distribution.
Li Cuiping et al. used a battery energy storage system to assist in the frequency modulation of thermal power units, significantly improving the frequency modulation effect, smoothing the unit output power and reducing unit wear.
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 %.
When the Energy Storage System (ESS) participates in the secondary frequency regulation, the traditional control strategy generally adopts the simplified first-order inertia model, and the power allocated to each energy storage unit follows the principle of equal distribution.
The dynamic frequency modulation model of the whole regional power grid is composed of thermal power units, energy storage systems, nonlinear frequency difference signal decomposition, fire-storage cooperative fuzzy control power distribution, energy storage system output control and other components.
