Abstract: The present invention relates to a energy allocation system for operating at least an energy storage device (1) to substantially balance the energy consumed by the energy storage device with the energy supplied thereto, comprising the steps of: determining a power flexibility of the energy storage device by generating an upper time-varying power function (P_max(t)) and a lower time-varying power function (P_min(t)) 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 (1) is in use; predicting energy consumption data (E_consumed(t)) 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 (E_consumed(t)) 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 (E_consumed(t)) is predicted; generating a time-varying upper energy function (4) for the demand prediction that defines an uppermost limit for the supply of energy to the device; generating a time- varying lower energy function (5) for the demand prediction that defines a lowermost limit for the supply of energy to the device, and supplying energy (6') to the device in a range (6) defined by and between the limits specified by the upper energy function (5) and the lower energy function (4).

Abstract: A plurality of devices (4, 5, 6, 7), such as electric vehicles, is adapted to consume, store and/or supply energy. A method comprises the steps of transmitting local power cost functions (cd) of a group of the devices (4, 5, 6, 7) and/or power usage profiles of the devices (4, 5, 6, 7) for a predetermined time slot to an assigned aggregation node device (8, 9), and at the aggregation node device (8, 9), generating aggregated data as a function of the received local power cost functions (cd) and/or power usage profiles, transmitting the aggregated data to a central processing device (10), and at the central processing device (10), optimizing a global cost function for allocating power to the devices (4, 5, 6, 7) as a function of the aggregated data. The method allows efficient management of the fluctuations of power supply and demand in a power grid, particularly where distributed energy sources (such as solar and wind) are used.
