Does a battery energy storage system participate in primary frequency modulation?
This paper proposes a comprehensive control strategy for a battery energy storage system (BESS) participating in primary frequency modulation (FM) while considering the state of charge (SOC) recovery.
How do Bess and thermal power units respond to frequency fluctuations?
The quantity of responses from the BESS and thermal power units to slight power system frequency fluctuations is diminished by adjusting the BESS's FM dead zone while conscientiously considering the service life of both the BESS and thermal units [25, 26]. The SOC of the BESS and its output are also closely related.
What are the disadvantages of frequency modulation of thermal power unit?
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.
Why is frequency stability a problem in power systems?
Moreover, frequency stability can no longer be guaranteed when the active power of the power system is severely disturbed [3, 4], while the high uncertainty of new energy incorporation leads to a severe shortage of frequency modulation (FM) capabilities .
What is a battery energy storage system (BESS)?
The battery energy storage system (BESS), which can be precisely regulated, has high response speeds and provides bi-directional charging and discharging. Moreover, these systems have become the main means of FM to assist conventional units, and domestic and international studies have also proven that BESS has a strong FM capability .
How does no-storage control affect system frequency?
From Figure 5a, it can be seen that the system frequency deteriorates fastest under the no-storage strategy, and the lowest frequency reached after the perturbation is smaller than that of the two comparison experiments. The conventional control strategy is to use virtual sag control and virtual inertia control to coordinate the outgoing force.
