  • Patent number: 7761910
    Abstract: A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes multiple intelligent electronic devices (“IED's”) distributed throughout the power distribution system to manage the flow and consumption of power from the system. The IED's are linked via a network to back-end servers. Security mechanisms are further provided which protect and otherwise ensure the authenticity of communications transmitted via the network in furtherance of the management of the distribution and consumption of electrical power by the architecture. In particular, public key cryptography is employed to identify components of the architecture and provide for secure communication of power management data among those components. Further, certificates and certificate authorities are utilized to further ensure integrity of the security mechanism.

  • Patent number: 7734380
    Abstract: A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes multiple intelligent electronic devices (“IED's”) distributed throughout the power distribution system to manage the flow and consumption of power from the system using real time communications. Power management application software and/or hardware components operate on the IED's and the back-end servers and inter-operate via the network to implement a power management application. The architecture provides a scalable and cost effective framework of hardware and software upon which such power management applications can operate to manage the distribution and consumption of electrical power by one or more utilities/suppliers and/or customers which provide and utilize the power distribution system.

  • Patent number: 6990395
    Abstract: A power management architecture for an electrical power distribution system that includes multiple intelligent electronic devices (“IED's”) distributed throughout the power distribution system to manage the flow and consumption of power from the system is disclosed. The IED's are linked via a network. Power management application components operate on the IED's, and inter-operate via the network to implement a power management application. The architecture provides a secure framework of hardware and software upon which such power management applications can operate to manage the distribution and consumption of electrical power by one or more utilities/suppliers and/or customers which provide and utilize the power distribution system. In particular, each IED is capable of establishing multiple encryption keys that confer different access rights on the IED. The encryption keys affect access to commands that the IED receives and restricts access to communications that the IED sends out over the network.

  • Patent number: 6792337
    Abstract: A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes intelligent electronic devices (“IED's”) with the capability to monitor and control attached slave devices, and provide capability to communicate between multiple devices in a variety of communication protocols. A master IED in the master/slave architecture performs power management functions on the data received from the slave IED's. Further, the IED's with master functionality provide web server capabilities, allowing a user to view processed data over an open Internet protocol, such as HTTP (“Hyper Text Transfer Protocol”).
