6 FAQs about [Hydropower agc energy storage frequency regulation technology]

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 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 the frequency regulation system of a regional power grid?

The frequency regulation system of the regional power grid equipped with energy storage comprises dispatching agencies, conventional thermal power units, battery energy storage systems, power conversion systems (PCS), transformers and power distribution, main power grids, and electrical protection systems.

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.

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 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.
