6 FAQs about [Current status of energy storage agc frequency regulation]

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.

What is a double-layer automatic generation control (AGC) frequency regulation control method?

Aiming at the problem of power grid frequency regulation caused by the large-scale grid connection of new energy, this paper proposes a double-layer automatic generation control (AGC) frequency regulation control method that considers the operating economic cost and the consistency of the state of charge (SOC) of the energy storage.

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.

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.

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.

How does dynamic control of energy storage affect frequency regulation?

In the process of energy storage participating in frequency regulation, the dynamic control of energy storage SOC can effectively suppress SOC fluctuation and fully use the idle state of energy storage to fine-tune SOC so that the SOC can be adaptively restored to the reference value.
