In order to have proper monitoring, control and analysis on power systems, communication infrastructure plays an important role in modern systems.
The goal of the communication is to transfer information fast and correctly within the system, locally or globally to create the data for different purposes such as protection, control, monitoring, estimation, prediction, optimization etc. In order to have optimized power system, usually a control center collect information of current situation, and analyze the information for having an economic, reliable, stable power system and this cannot be possible unless there will be a proper way of collecting information, and sending commands properly to local systems. By using new technologies such as PMU (Phasor Measurement Unit) and implementing new ideas, investments and science, modern infrastructure of power system is changing gradually. Current and voltage synchrophasors can be used to observe the state of system, and improve the indices of reliability, stability and in one word performance. This cannot be accomplished unless the communication layer provides the information at the point of need.

Test bed consists of a small scale power grid, along with communication infrastructure, which can provide the basis for doing wide range of researches on different aspects of current issues in power and energy systems.
Variety of communication protocols, devices and methods and new ideas can be tested in a real time system, to improve the system goals and see the real physical result instantly.
In test bed by help of data acquisition devices, measured data will be provided and by the help of communication system, these information will be transferred to a local or global point of processing.
As an example, it can be seen that for controlling a frequency drive, which works as a prime mover of a synchronous generator, serial communication proivides the ability to send command to drive and read the gathered information of motor, available in drive for different purposes such as control or alarm systems or monitoring.
More technically speaking, that simple communication mentioned above changes to complex system, with more detailes in implementation.
