Abstract
The application discloses an AGC system load curve offset adjustment method and device, equipment and medium, and relates to the field of power system automatic generation control, and specifically comprises the following steps: for each node in a day generation plan offset period, determining a target time offset based on an initial time offset, a variable amplitude parameter, a water head parameter and a frequency parameter, wherein the variable amplitude is the change rate of active power; determining a target time stamp according to the target time offset and an original time stamp; and determining a load curve corresponding to the offset period based on the target time stamp and an active power value corresponding to the target time stamp. The application can realize automatic adjustment of periodized load curve offset.
