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 frequency regulation power optimization?

The frequency regulation power optimization framework for multiple resources is proposed. The cost, revenue, and performance indicators of hybrid energy storage during the regulation process are analyzed. The comprehensive efficiency evaluation system of energy storage by evaluating and weighing methods is established.

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.

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 to reduce frequency fluctuation using advanced energy storage system?

This paper presents a technique for reducing the frequency fluctuation using the Advanced Energy Storage System with utility inductors. The proposed ESS acts as a load and gets itself charged as well as can supply power to maintain balance in demand and supply.
