1. A method for operating at least an energy storage device to substantially balance the energy consumed by the energy storage device with the energy supplied thereto, comprising:

  • determining a power flexibility of the energy storage device by generating an upper time-varying power function and a lower time-varying power function that respectively represent the maximum power and the minimum power that can be supplied to the device at any given point in time when the energy storage device is in use;

    predicting energy consumption data per discrete time-slots over a given time-window for the device;

    predicting a demand for energy by the device in a given planning time-period by consecutively accumulating the predicted energy consumption data per discrete time-slots in the planning time-period that correspond with the discrete time-slots in the time-window over which the energy consumption data is predicted;

    generating a time-varying upper energy function for the demand prediction that defines an uppermost limit for the supply of energy to the device;

    generating a time-varying lower energy function for the demand prediction that defines a lowermost limit for the supply of energy to the device, andsupplying energy to the device in a range defined by and between the limits specified by the upper energy function and the lower energy function,wherein, in the generating of the upper energy function, energy is taken to be supplied to the device immediately after the occurrence of an energy consumption event and so as to replenish the device with the energy consumed in the energy consumption event.
