Carbon reduction targets and the falling price of renewables is causing the utility landscape to change and innovate more quickly than ever before. The challenge from a reliability standpoint is how to integrate new technologies while maintaining stability and balance in the grid. Digital technologies will play a key role in making this possible, responding to problems of intermittency and the distribution of energy resources, all the while ensuring greater agility, oversight, and resilience.
The digital substation is a key part of the new utility landscape. In this paper, we look at the communications foundation that will enable the digitalization of substations and what network characteristics the communications infrastructure must meet. We present Nokia’s digital substation communications system blueprint.
