6 FAQs about [Energy storage power stations need power distribution]

What are energy storage stations?

As a flexible power resource, energy storage stations can store and release electrical energy according to the need, thereby balancing load and supply in the power system and enhancing its reliability and cost-effectiveness .

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.

How to solve power distribution problem in energy storage power stations?

In the power computational distribution layer, the operating mode of the ESSs is divided by establishing the working partition of the ES. An adaptive multi-energy storage dynamic distribution model is proposed to solve the power distribution problem of each energy storage power station.

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.

Why do energy storage power stations output more power?

According to the above distribution method, when the ESSs outputs power, the unit with higher discharge capacity outputs more power, so as to avoid the occurrence of pre-shutdown and over-discharge due to the output power of the energy storage power station with lower discharge capacity.
