Smart grid communication requirements for the high voltage power system

The vision of a smarter grid very much depends on a fast communication infrastructure that can provide near realtime data delivery and can handle security issues. These issues become more and more critical when we imagine having phasor measurement units everywhere in the power grid. The latency and bandwidth requirements for smart grid are two very critical issues among these. This paper attempts to provide a simulation approach to understand these issues. A possible communication structure is then presented with the results on the latency and bandwidth for IEEE 14 bus, 30 bus, and 57 bus systems.
