Abstract

A computer-based electrical power management and allocation system is provided that collects demand for electric power usage and allocates electric power supply in satisfaction thereof. A load control server is used to collect and schedule electrical power start and stop requests according to policies established by either or both of the electric power consumers and electric power suppliers. The energy system collects accumulation messages to reserve electrical power and processes them using the prescribed customer and supplier policies and according to an overall optimization criterion of the energy system. Stop messages are then subsequently issued to cease device operation and the devices are then moved to a reservation pool until the energy system'"'"'s operational criterion is relaxed or the accumulation messages become obsolete. Similar accumulation requests for delayed or conservation-based operation may also be applied to the distribution of other utilities, such as water, natural gas, or guaranteed internet bandwidth.

said load control system having an active pool data structure containing a group of computer-controlled devices for which computer-based start messages have been received and for which said associated computer-controlled devices have been started by said load control system for said customer, said load control system having a reservation pool data structure containing a group of computer-controlled devices for which computer-based start messages have been received and for which said associated computer-controlled devices have also received demand delayed messages from said load control system, said load control system establishing an active pool parameter according to which said active pool data structure is managed, said method comprising;

receiving at said demand response aggregator a computer-based electric service price message from said electric power provider, said electric service price message indicating a higher price at which said electric power will be supplied to said group of computer controlled devices with said active pool data structure, said higher price being greater than a lower price at which said group of computer-controlled devices within said active pool data structure are currently operating, said higher price being determined by said at least one computer at said electric power supplier and in response to an increase in said total electric power load;

changing the value of said active pool parameter in response to receiving said electric service price message;

moving a group of computer-controlled devices from said active pool data structure to said reservation pool data structure after making said change; and

sending a computer-based delayed demand message to said group of said moved computer controlled devices so as to temporarily prevent said group of moved computer-controlled devices from drawing electric power from said electric power distribution system, said prevented group of computer-controlled devices causing said total electric power load determined by said electric power provider to decrease, said decrease in said total electric power load comprising negative watts, said negative watts causing a cost savings for said electric power supplier; and

selling said negative watts to said electric power supplier by said demand response aggregator.

2. The method of claim 1 wherein said active pool parameter is a cost of electricity to said electric power supplier.

3. The method of claim 1 wherein said electric power supplier is an independent system operator or an electric power utility.

4. The method of claim 1 wherein said active pool parameter is conditioned on a state of occupancy of a home, said customer policies of said group of customers configured to accept demand delay messages for said group of computer controlled devices within said home when said home is unoccupied, said change in the value of said active pool parameter causing said demand response aggregator to issue said demand delay messages to said group of computer controlled devices based on said active pool parameter being set to unoccupied and said customer policies of said group of customers.

5. The method of claim 1 wherein some of said customers have a local battery coupled to said at least one computer-controlled device, said policies of said group of customers include a local battery option, said setting of said local battery option causing said battery coupled computer-controlled devices of said customer to operate on electrical power from said local battery when said coupled computer-controlled devices receive said demand delay messages.

6. The method of claim 1 wherein some of said customers have a local battery coupled to said at least one computer-controlled device, said policies of said group of customers include a local battery option, said setting of said local battery option causing said battery coupled computer-controlled devices of said customer to operate on electrical power from said local battery when said coupled computer-controlled devices receive said demand delay messages.
