The Construction of Interconnected Communication System among Smart Grid and a variety of Networks

Faced with the increasingly severe pressure on resources and environment, power grid intellectualization is an important method to promote the development of renewable energy sources as well as achieve optimal allocation of resources and environmental protection. This paper proposes the structure of interconnected communication system among smart grid and varieties of networks. The core of the structure can be summed up as follows: if the communication system which interconnects smart grid, micro-grid and enterprise (or large electricity user) via electric power communication WAN, as well as the communication network between smart grid and Internet of Things via Internet could be established, the characteristics of real-time, efficient, reliable data-exchange, information and resource sharing, and dependable, secure intelligent protection and control would be achieved for the purpose of the realization of smart grid marked as " strong, cost-effective, environmental-friendly, open and interactive".
