4 FAQs about Frequency regulation of thermal power plant energy storage system 8c

How does frequency regulation affect energy storage?

When the energy storage system must be charged under the condition of frequency regulation, the charge power absorbed by the energy storage system steadily decreases when the SOC is at a high boundary value, and it eventually cannot absorb the charge power when the SOC hits the critical value.

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.

What is the frequency modulation control strategy of fire-storage AGC?

In this paper, the frequency modulation control strategy of fire-storage AGC considering flexible load characteristics is studied. The operating states of the system are divided by the frequency deviation partition, and different adjusting methods and means are adopted to maintain the stability of the system under different operating states.

What is a thermal power unit control approach?

The proposed control approach is compared to the operating conditions of single thermal power unit regulation, thermal power energy storage combined regulation, and thermal power flexible load combined regulation using the model developed in this article. The system's primary source of power is a thermal power unit.
