6 FAQs about [Tender for thermal power energy storage frequency regulation project]
How a hybrid energy storage system can support frequency regulation?
The hybrid energy storage system combined with coal fired thermal power plant in order to support frequency regulation project integrates the advantages of “fast charging and discharging” of flywheel battery and “robustness” of lithium battery, which not only expands the total system capacity, but also improves the battery durability.
What is the difference between auxiliary regulation and energy storage system?
The output fluctuation of the thermal power unit is the biggest when the auxiliary regulation is only from the load side, and is relatively small when the frequency change rate is fast. The output of the energy storage system is small while the SOC consumption is small, and the frequency stability is not affected.
How does frequency regulation affect the discharge power of energy storage system?
Under the condition of frequency regulation, the discharge power of the energy storage system will gradually decrease when the SOC is at low boundary value, and finally it will not be able to discharge when it reaches the critical value of SOC. When the value of Kpa is 10, λ When the value of is 20, it is shown in Fig. 6.
What is the integrated regulation strategy for energy storage systems?
the integrated regulation strategy proposed in this paper determines the switching time and operating depth of the energy storage system and the flexible load, and makes rational and effective use of the frequency modulation resources to regulate, giving full play to their respective advantages.
