Problems solved by technology

Although some literatures consider the cost of energy storage loss in the process of energy storage participating in the secondary frequency regulation, but in order to implement the frequency regulation requirements of medium and high frequencies, factors such as frequent charge and discharge switching, and a high proportion of regulation depth will inevitably accelerate the battery life attenuation.

Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0047] Such as figure 1 As shown, the control method for the secondary frequency regulation of the power grid includes the following steps:

[0048] Step 1, in response to receiving the regional control demand command, the first low-pass filter is used to decompose the regional control demand command, and the frequency modulation power allocated to the unit and the frequency modulation power allocated to the hybrid energy storage system are obtained;

[0049] Step 2, using the second low-pass filter to decompose the frequency modulation power allocated to the hybrid energy storage system to obtain the frequency modulation power allocated to the lithium battery and the frequency modulation power...

Abstract

The invention discloses a power grid secondary frequency modulation control method and a system, a storage medium and computing equipment. According to the power grid secondary frequency modulation control method and system, frequency modulation required power is reasonably distributed among a unit, a lithium battery and a lead-carbon battery, the frequency modulation pressure of the unit is relieved, the unit operates in a smooth state, mechanical abrasion and unit coal consumption are effectively reduced, the service life of a hybrid energy storage battery is prolonged, and meanwhile, the station frequency modulation performance can be effectively improved, the operation cost of the system is reduced, and higher frequency modulation benefits are obtained.

Description

technical field [0001] The invention relates to a control method, a system, a storage medium and a computing device for secondary frequency regulation of a power grid, and belongs to the field of secondary frequency regulation of a power grid. Background technique [0002] As the application of energy storage batteries participating in secondary frequency modulation becomes more and more extensive, how to realize the reasonable distribution of frequency modulation signals between the unit and the battery has become a research hotspot. Although some literatures consider the cost of energy storage loss in the process of energy storage participating in the secondary frequency regulation, but in order to implement the frequency regulation requirements of medium and high frequencies, factors such as frequent charging and discharging switching, high proportion of regulation depth and other factors inevitably accelerate the battery life attenuation. .
