Thoughts on future Internet based power system information network architecture

The rapid development of information technology (IT) is pushing the power system information network to a remarkable innovation state. Internet/Intranet will play an important role in power system information network. This paper reviews the current Internet applications in power systems in areas such as remote information access, geographic information systems (GIS), SCADA/EMS, condition monitoring and predictive maintenance, customers service, power market, power quality, and distance education/training. Though the application of the Internet has been developed in many areas, scattered and individual applications hampered the large-scale integration of power system information source. Some preliminary thoughts on a future Internet based power system information network (PSIN) architecture are presented. The paper draws a blueprint for future PSIN infrastructure development.
