  • Patent number: 11870256
    Abstract: This invention relates to a method for optimising usage 5 of electricity from the grid and energy storage comprising: forecasting a predetermined number of hours of load at a predetermined interval to determine a forecasted load profile; subtracting a peak load from the forecasted load profile by a maximum amount of electricity that can be charged into or discharged from the energy storage to determine a subtracted peak; smoothening peaks 10 within 30 minutes period that are more than the subtracted peak to obtain a final forecast result; and determining optimised battery setpoint actions based on the final forecast result and energy storage operating constraints.
