An overview on the architecture of information system in smart power grids

Abstract

Smart power grids realize the further precise control of the energy and power by means of the advanced information technology based on the traditional power grid. Through the definition of smart power grids, the present situation of domestic and foreign development, and the main technical difficulties and challenges emphatically, this paper puts forward the suitable architecture of the information system for smart power grids from information technology perspective. The structure is divided into three levels: the first one is the infrastructure including the basic equipment of power system and the communication network, the second one is the supporting platform including the sensing measurement, data storage, analysis and decision-making, and the control and execution platform, the last one is the application system including the side of power supply , the grid and electricity . So it can really realize the interaction of physical, information and application system, meanwhile, it can also realize the high integration of information, energy and the business flow. This paper summarizes particularly the present situation of various aspects on the technology development the architecture involves, at the same time, it also points out the research direction that may bring the breakthrough in the future.
