6 FAQs about [Tiered design scheme for energy storage power station]

How is energy storage power station distributed?

The energy storage power station is dynamically distributed according to the chargeable/dischargeable capacity, the critical over-charging ES 1# reversely discharges 0.1 MW, and the ES 2# multi-absorption power is 1.1 MW. The system has rich power of 0.7MW in 1.5–2.5 s.

Do energy storage power stations need to be modified?

Although some energy storage power stations are in the overcharge range in modes 2, 5 and 6, the system requires energy storage discharging. So it does not need to be modified, and it can be dynamically distributed based on the chargeable/dischargeable amount of ES.
