A Cognitive Radio Enabled Smart Grid Testbed Based on Software Defined Radio and Real Time Digital Simulator

With the development of Smart Grid, there is an increasing need for the inter discipline research, analysis and evaluation, especially in the joint research area of communication system and power system. In this paper, we propose a Cognitive Radio enabled Smart Grid testbed, which is able to provide real time emulation of the real Smart Grid systems. A prototype with USRP N210, data acquisition and actuator module and Real Time Digital Simulator is implemented, which verifies the framework of the proposed testbed architecture. Evaluation cases show that the proposed testbed is able to provide an average of 9.7ms round trip communication latency and validate real time Smart Grid applications such as voltage stability control.
