Power Supply Control Method And System
Provided is a power supply control method and system capable of efficiently adjusting an ESS charge/discharge operation on the basis of a load measurement value and a power generation amount measurement value. The power supply control system includes: a power generation amount measurement unit configured to measure a current power generation amount value; a power generation amount forecast unit configured to forecast a power generation amount value; a load measurement unit configured to measure a current load value; a load forecast unit configured to forecast a load value; a correction value computation unit configured to correct at least one of a peak cut value, a load leveling value, the forecasted power generation amount, and the load forecast value on the basis of at least one of a difference between the power generation amount measurement unit and the power generation amount forecast unit and a difference between the load measurement unit and the load forecast unit; and an ESS charge/discharge operation output control unit configured to control an output of an ESS charge/discharge operation by applying a correction value computed by the correction value computation unit.

- 1. A power supply control method comprising:
a measurement process for measuring a power generation amount and a load value; a comparison process for comparing the power generation amount and the load value measured by the measurement process with a forecasted power generation amount and a load forecast value forecasted in advance; a correction value computation process for correcting at least one of, a peak cut value, a load leveling value, the forecasted power generation amount, and the load forecast value on the basis of a result of the comparison of the comparison process; and an energy storage system (ESS) charge/discharge operation output control process for controlling an output of an ESS charge/discharge operation by applying a correction value computed in the correction value computation process.
- 10. A power supply control system comprising:
a power generation amount measurement unit configured to measure a current power generation amount value; a power generation amount forecast unit configured to forecast a power generation amount value; a load measurement unit configured to measure a current load value; a load forecast unit configured to forecast a load value; a correction value computation unit configured to correct at least one of a peak cut value, a load leveling value, the forecasted power generation amount, and the load forecast value on the basis of at least one of a difference between the power generation amount measurement unit and the power generation amount forecast unit and a difference between the load measurement unit and the load forecast unit; and an ESS charge/discharge operation output control unit configured to control an output of an ESS charge/discharge operation by applying a correction value computed by the correction value computation unit.
