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 %.
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.
The frequency modulation of thermal power unit has disadvantages such as long response time and slow climbing speed. Battery energy storage has gradually become a research hotspot in power system frequency modulation due to its quick response and flexible regulation.
In summary, control scheme D is adopted when hybrid energy storage combined thermal power units are configured to participate in frequency modulation, namely, both flywheel energy storage and lithium battery energy storage adopt an adaptive variable coefficient control strategy to achieve the best effect.
