Abstract

The invention discloses an energy storage power station, a frequency modulation control method and a storage medium. The frequency modulation control method comprises the steps of collecting real-timevoltage data of a power grid; calculating the real-time frequency and the frequency change rate of the power grid according to the real-time voltage data of the power grid; and selecting a corresponding frequency control algorithm according to the amplitude of the real-time frequency and the frequency change rate of the power grid. The optimal frequency modulation control for the energy storage power station can be formed according to the invention.

Description

technical field [0001] The invention relates to the technical field of power system automation, in particular to an energy storage power station, a frequency modulation control method and a storage medium. Background technique [0002] Energy storage power stations can provide various services such as peak regulation, frequency regulation, backup, black start, demand response support, and improvement of new energy consumption capacity for grid operation, and are an important means to improve the flexibility, economy, and security of traditional power systems. In terms of power grid frequency regulation, energy storage power stations use power electronic components as interfaces and have fast frequency regulation capabilities, showing huge advantages in power grid frequency regulation. [0003] At present, most of the energy storage power stations participating in the frequency modulation control of the power grid adopt a single control method, and it is necessary to find an ...
