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.
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.
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.
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.
Therefore, a multi-type energy storage (ES) configuration method considering State of Charge (SOC) partitioning and frequency regulation performance matching is proposed for primary frequency regulation. Firstly, the Automatic Generation Control (AGC) signal is decomposed and reconstructed using the variational mode decomposition (VMD) method.
At the regional control level, an economically optimized dynamic frequency regulation responsibility distribution between the unit and the energy storage is realized, and the idle time of energy storage is fully used for SOC management to effectively suppress the fluctuation of the energy storage SOC.
