[0043] Figure 1 The figure is a flow chart of a method for controlling the frequency response of flywheel energy storage according to a preferred embodiment of the present invention.

[0044] This paper proposes a flywheel energy storage frequency response control logic and a simulation method based on this flywheel energy storage frequency response control logic. Based on the basic structure of flywheel energy storage, this paper studies the principles and methods of thermal power units and flywheel energy storage participating in primary frequency regulation, and proposes a control logic for flywheel energy storage frequency response. Through simulation modeling of the thermal power speed regulation system and the flywheel energy storage system in a coupled thermal power and flywheel energy storage system, this paper improves the simulation method for the overall coupled thermal power and flywheel energy storage system.

[0046] like Figure 1 As shown, the present invention provides a method for controlling the frequency response of a flywheel energy storage, the method comprising:

[0047] Step 101: Obtain the frequency change Δf of the flywheel energy storage system and the power P of the synchronous generator set E ;

[0048] Step 102: The frequency variation Δf is passed through a first sampling first-order inertia link and a first limiter, and then multiplied by a frequency response coefficient K to generate a first branch power signal, and the first branch power signal is input into a power superposition link;

[0049] Step 103: Set the synchronous generator power P E After the second sampling first-order inertia link and the delay link e -tsThen, a second branch power signal is generated and inputted into the power superposition link;

[0050] Step 104: Superimpose the first branch power signal and the second branch power signal to generate a superimposed signal, and amplify the superimposed signal by the expected power factor K. P After amplification, the power control command signal P of the flywheel energy storage system is output after the second limiting. fv , through the power control command signal P fv Control the frequency response of flywheel energy storage.
