Generator AGC energy storage auxiliary frequency regulation system

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.

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.

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 of two area power system based on?
