Technical FAQs 4

Can battery energy storage improve frequency modulation of thermal power units?

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.

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 %.

Which control scheme is adopted in hybrid energy storage combined thermal power units?

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.

What is a battery energy storage system (BESS)?

Battery energy storage systems (BESS) based on lithium-ion batteries (LIBs) are able to smooth out the variability of wind and photovoltaic power generation due to the rapid response capability of LIBs. It can also actively support grid frequency regulation requirements.
