Embodiment Construction

[0016] Systems and methods for managing data communications in a smart grid communications network are described below. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the specification. It will be apparent, however, to one skilled in the art that the embodiments may be practiced without these specific details. In other instances, structures and devices are shown in block diagram form in order to avoid obscuring the description. For example, the description below is described in one embodiment with respect to a user interface and specific hardware. However, the description applies to any kind of computing device capable of receiving data and commands, and to any peripheral device that provides services.

[0017] Reference in this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the em...

Abstract

A system and method for managing smart grid communication is disclosed. The system includes a communication module, a discovery module, a translation module and a smart grid module. The communication module receives data initiating smart grid communication between a utility server and a communication node. The discovery module identifies a server protocol used by the utility server to communicate with the communication node. The discovery module identifies a node protocol used by the communication node to communicate with the utility server. The node protocol is incompatible with the server protocol. The translation module performs a protocol translation between the server protocol and the node protocol. The smart grid module handles the smart grid communication between the utility server and the communication node using the protocol translation.

Description

technical field [0001] This specification relates to smart grid (smart grid) technology. In particular, this specification relates to managing data communications in smart grid communications networks. Background technique [0002] A utility server (utility server) and an electric vehicle can communicate with each other using a single communication protocol. However, the communication protocol used for data communication between the utility server and the electric vehicle may be different in each geographic location. For example, in the US, utility servers and electric vehicles can use the Smart Energy Profile (SEP) 2.0 protocol for data communication; however, in Japan, the ECHONET Lite protocol can be used. It is difficult for original equipment manufacturers (OEMs) to produce electric vehicles that implement different communication protocols. In addition, the utility server may update the communication protocol within a short period of time, or utilize a new communicat...
