Abstract

The application discloses a low-frequency load shedding control method and device, terminal equipment and storage medium, and belongs to the field of power system stability control analysis. The method is as follows: acquiring frequency modulation coefficients corresponding to each load when distributed photovoltaic participates in frequency modulation and a low-frequency load shedding frequency action value, and collecting system active disturbance data of a current power grid; inputting the system active disturbance data and the low-frequency load shedding frequency action value into a preset power grid comprehensive active control model, so that the power grid comprehensive active control model outputs a low-frequency load shedding total control quantity according to the system active disturbance data; initializing and solving a low-frequency load shedding optimal control model with the maximum frequency modulation performance gain as an optimization objective according to the low-frequency load shedding total control quantity and the frequency modulation coefficients corresponding to each load, and determining and performing low-frequency load shedding control according to the optimal low-frequency load shedding control quantity of each load. The application can accurately calculate the low-frequency load shedding total control quantity under the distributed photovoltaic scene and realize optimal load shedding distribution control among loads.
