Method and system for allocating energy
First Claim
1. A system for allocating energy, comprising:
- a plurality of devices, wherein each device is configured to consume, store and/or supply energy, and each device is assigned to a group of devices;
one aggregation node device assigned to each group of devices, the aggregation node device being configured to generate aggregated data as a function of at least one of received power cost functions or power usage profiles, wherein the aggregated data includes inner state information for each of a selection of devices; and
a transmitter for transmitting the aggregated data to a central processing device, the aggregated data including inner state information for each of the selection of devices, the central processing device being configured to optimize a global cost function for allocating power to the devices as a function of the aggregated data, the optimizing comprising generating, at the central processing device, device optimization parameters for each of the devices, and transmitting the device optimization parameters to each of the devices via the aggregation node device,wherein the aggregation node device is configured to aggregate data received from the devices and transmit the aggregated data to the central processing device.

Abstract
A method for allocating energy to a plurality of devices, wherein each device is configured to consume, store and/or supply energy, the method includes the steps of: assigning each device to a group of devices; assigning an aggregation node device to each group of devices; for a selection of devices transmitting local power cost functions of the devices and/or power usage profiles of the devices with respect to a predetermined time slot to the assigned aggregation node device; at the aggregation node device, generating aggregated data as a function of the received local power cost functions and/or power usage profiles; transmitting the aggregated data to a central processing device; at the central processing device, optimizing a global cost function for allocating power to the devices as a function of the aggregated data.
