energy storage enables peak load regulation and frequency regulation of thermal power plants

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.

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.

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.

Do flexible resources support multi-timescale regulation of power systems?

Here, we focused on this subject while conducting our research. The multi-timescale regulation capability of the power system (peak and frequency regulation, etc.) is supported by flexible resources, whose capacity requirements depend on renewable energy sources and load power uncertainty characteristics.

Do flexible loads participate in regulation to make storage more flexible?

After 105 min, it is obvious that the combined regulation of fire and storage is not enough to cope with the frequency change of the system by the power of storage alone, so the storage can no longer be put into operation. This shows from the side that flexible loads participate in regulation to make storage more flexible.

Numerical studies show that with a confidence level of 90% for satisfying demand, the 49.5% RE penetration system (the maximum load is .42 MW) needs ES power and capacity of MW and MWh for peaking and ES power and capacity of 478 MW and 47 MWh for frequency regulation.
