6 FAQs about [Design scheme for thermal power energy storage frequency regulation]

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 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.

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.

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.

Can flexible load and energy storage be used to regulate frequency?

The method of using flexible load on the load side and energy storage on the power side to regulate frequency is proposed. The depth limit of energy storage action is proposed, which clarifies the dead zone and the maximum output limit.

What is the operation status of energy storage system (SoC)?

Among them, the operation status of SOC can be divided into the root mean square value SOCrms of SOC and the operation range SOCmin – SOCmax of SOC, and the benchmark value of SOC is 0.5. The greater the contribution of energy storage system, the greater the role of energy storage system in auxiliary power grid frequency modulation.
