Intelligent integrated grid with a user and a communication method for a communication system

The present invention relates to a smart grid integrated communication system with a user and a communication method, the system includes a grid-side system, the data center system and a user side system; user side of the system includes a user-side smart device connected via the interface to each other, and five user-side energy management system, the energy management system via the user-side interfaces four devices connected with the gateway, the gateway device connected to the interface via respectively two and three interfaces with the grid-side system and the data center system; the grid side system connected to the data center via the interface system VI. The method is: analyze information interaction with a user demand for smart grid; information exchange definition of the functional specification; and analysis functions related to object interaction process; statically defined information model; define dynamic information exchange model; communication protocol mapping; communication technology selected. The present invention support network and user information exchange to improve the entire energy supply chain efficiency and environmental friendliness to power at the center.
