Phasor -based Wide Area Monitoring and Control (WAMC) system promise to improve the monitoring of power grid across large geographic areas and accordingly controlling grid in more efficient and intelligent ways. In order to have confidence on the correctness, performance and reliability of applications used in WAMC system in real world scenarios, pseudo-real test beds where the requirements for the applications and their supporting Information and Communication Technology (ICT) can be quantified and analyzed. In this paper, a WAMC system testing platform is proposed to facilitate the real-time simulation of dynamic power grid, the ICT infrastructure that overlays the grid and WAMC applications. The proposed platform consists of OPNET as a powerful communication network simulator connected to real-time power system simulator on one side through virtualized Phasor Measurement Unit device, and linked to end point stations such as Phasor Data Concentrator or application on the other side through OPNET’s real-simulation gateway. A set of proof of concept scenarios using this framework is presented.
