Abstract

In one embodiment of this invention, identical communicating node elements are constructed and placed throughout a power delivery network. Each of these node elements supplies features and options that facilitate peer-to-peer communications, data and service aggregation, propagated interfaces and distributed computational power. The network of interacting node elements, built with a common architecture, gives the power delivery network advanced capabilities for utilities and customers. These advanced capabilities include self-healing, highly secure communications, real-time interactions between any devices, and so on.

a plurality of node elements deployable on said electric power network and each having a respective global port and an inward port, the electric power network having a plurality of hierarchy levels, including a hierarchy of high voltage, medium voltage, and low voltage, and wherein at least one node element is deployed at each hierarchy level;

each node element having a global data store that is populated with information supplied via said global port and is accessible via said inward port;

each node element having a local data store that is populated with information supplied via said inward port and is accessible via said global port;

each node element being configured to selectably support at least one of three planes of interaction using the information maintained within said global and inward data stores;

a power analysis plane of interaction,

a data plane of interaction, and

a control plane of interaction,

wherein each node element allows a plurality of load devices to exchange data, through the node element, using respective different protocols of the load devices; and

wherein each node element includes a proxy having a universal format interface that makes available a local control interface of a first local load device available and that allows remote control of the first local load device, through the universal format interface, using a universal format different from a local control protocol of the first load device.

2. The communications system architecture of claim 1 wherein each node element is implemented using modular blocks providing sets of features that can be selectively included or excluded.

3. The communications system architecture of claim 1 wherein each node element is adapted to selectively enable and disable selected ones of said planes of interaction.

4. The communications system architecture of claim 2 wherein said sets of features include features to selectively enable and disable said planes of interaction.

5. The communications system architecture of claim 1 wherein said global data store is configured to store aggregate information that is periodically updated, wherein the aggregation information provides knowledge of faults in the electric power network, wherein the node element is reconfigured for supporting at least one of the three planes of interaction based on the knowledge.

6. The communications system architecture of claim 1 wherein said local data store is configured to store aggregate information that is periodically updated.
