HOME / Lithium Battery Energy Storage Frequency Modulation - G01 Smart Energy
A paradigm shift in power generation technologies is happening all over the world. This results in replacement of conventional synchronous machines with inertia less power electronic interfaced renewabl.
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.
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.
Fig. 15 shows graphs of the frequency and the power response of the energy storage system during a frequency event trigger. A 500 MW imbalance was created within the system, resulting in a substantial drop in frequency. The change in frequency was observed by the ESS in the laboratory, which dispatched power according to the EFR response curve.
However, a comparison has been made based on the power and energy characteristics of popular BES technologies. The normalized characteristics of popular battery storage technologies are given in Table 4.
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.
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 .

Building on this analysis, this paper summarizes the limitations of the existing technologies and puts forward prospective development paths, including the development of multi-parameter coupled monitoring and warning technology, integrated and intelligent thermal management technology, clean and efficient extinguishing agents, and dynamic fire suppression strategies, aiming to provide solid theoretical support and technical guidance for the precise risk prevention and control of lithium-ion battery storage power stations.
With the advantages of high energy density, short response time and low economic cost, utility-scale lithium-ion battery energy storage systems are built and installed around the world. However, due to the thermal runaway characteristics of lithium-ion batteries, much more attention is attracted to the fire safety of battery energy storage systems.
According to the evidence, water-based fire extinguishing agents (such as water, AF-31, AF-21, etc.) show a better cooling effect when extinguishing lithium battery fires, and their cooling effect is more significant than that of gas fire extinguishing agents (such as carbon dioxide, heptafluoropropane).
However, manufacturing defects or non-compliance with safety norms can easily trigger thermal runaway in lithium batteries, leading to safety accidents such as fires and explosions. This highlights the urgent need for advanced lithium battery fire suppression technology.
High-quality fire extinguishing agents and effective fire extinguishing strategies are the main means and necessary measures to suppress disasters in the design of battery energy storage stations . Traditional fire extinguishing methods include isolation, asphyxiation, cooling, and chemical suppression .
To develop an appropriate solution for the specific application of managed stationary storage systems it was necessary to conduct a series of experiments and tests. Our work has shown that Li-ion battery energy storage systems can be a controllable application when it comes to fire protection.
