6 FAQs about [Energy storage agc frequency regulation policy]
What is the purpose of AGC frequency regulation control?
Objective Function of AGC Frequency Regulation Control: The essence of coordinated control of the joint participation of thermal power units and the energy storage in AGC frequency regulation is to allocate the AGC instructions issued by the dispatching center between the thermal power unit and the energy storage system.
Does SoC management affect unit-storage combined AGC frequency regulation performance?
In order to minimize the impact of SOC management on the unit-storage combined AGC frequency regulation performance, this paper chooses to perform fine-tuning management of SOC under conditions where load disturbance changes slowly and the battery energy storage system is in the idle state of 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.
How do you calculate AGC frequency regulation?
Therefore, the sum of frequency regulation active power commands borne by the thermal power unit and energy storage should be equal to the total AGC command at this moment, namely: (9) P agc, k = ∑ P U, i, k + ∑ P B, j, k Where Pagc,k is the AGC frequency regulation command sent by the dispatching center at time k.
What is AGC frequency modulation control based on variable load characteristics?
To address the aforementioned issues, an AGC frequency modulation control technique based on variable load characteristics is proposed, with frequency modulation and energy storage SOC restoration coordinated by flexible load response control on the load side. For flexible load, the centralized control mechanism is used first.
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.
