Study on the structure of electric power communication network of strong and Smart Grid in China

The paper analyses and studies the communication requirements of China Smart Grid including the power generation, transmission, substations, power distribution, electricity, scheduling and other major links. Then the shortage of the electric power communication network in China is investigated. The paper also proposes the structure of the future optical fiber backbone communication network, the power distribution communication network and the access network of the user side for China Smart Grid. Finally, the use of advanced communication technology toward future state grid is introduced.
