A Design Method for Information Network of Ubiquitous Power Internet of Things Based on Complex-network

Ubiquitous power internet of things provides smart grids with more advanced abilities such as comprehensive state awareness, efficient information processing, and convenient and flexible applications. It is an important pattern to realize intelligence of power grids. Therefore, the design method for information network of ubiquitous power internet of things needs to be improved to meet the requirements of the desirable services. This paper realizes node importance evaluation through complex network evaluation indexes, including node degree, betweenness coefficient, efficiency loss coefficient, and agglomeration lifting coefficient. Combining these indexes, a composite index is obtained to select vital nodes in a given power grid. This paper proposes a design method for information network of ubiquitous power internet of things through traversal algorithm and network evaluation index optimization. The information network will be only constructed on the vital nodes in order to increase economy and keep effect. Through the comparison of different cases, the information network designed by proposed method is verified to be efficient and economical in the case of data collecting and transmitting.
