Problems solved by technology

The power demand of the grid is increasing year by year. In addition to stabilizing the fluctuation of load demand, the backup capacity also needs to withstand the impact of intermittent power supply from renewable energy sources, which raises the challenge of grid frequency stability control.

Abstract

The present disclosure relates to a load control system and a load control method. The load control system includes a load monitoring device, an automatic reading device, and a control device. The load monitoring device is configured to monitor the load power generated by the load according to the power generation amount of a power grid and the grid frequency, and the grid frequency is changed tothe grid change frequency according to the change of the grid power generation amount and the load power. The automatic reading device is configured to read the grid change frequency. The control device is configured to increase or decrease the load power according to a difference between an allowable frequency range and the grid change frequency to reduce the difference.

Description

technical field [0001] The present disclosure relates to a load control system and a load control method, in particular to a load control system and a load control method capable of controlling the power of a load according to changes in grid power generation and grid frequency. Background technique [0002] Grid frequency is a reference index for the reliability of power system operation, and the balance of supply and demand depends on the power company's generator sets and load forecasts. The power demand of the grid is increasing year by year. In addition to stabilizing the fluctuation of load demand, the backup capacity also needs to withstand the impact of intermittent power supply from renewable energy sources, which raises the challenge of grid frequency stability control. [0003] When the power provided by the power supply end cannot load the power consumed by the power consumption end in time, such as peak power consumption in summer or failure of the power generat...
