Abstract [en]

Operating the large-scaled electric power grid closer to parameters limit as a solution to restriction on transmission lines expansion, or electrical marketing issues such as reregulation which brought the connection of national grids to surrounding neighbor’s grid may make the control of the power system more complicated than before. In this situation, technologies like PMU-based Wide Area Monitoring and Control System are developed to improve the monitoring of power grid across large geographic areas and accordingly controlling grid in more efficient and intelligent way. WAMC system bring a new opportunity for applications in terms of data availability, accuracy and high sampling rate which in turns cause applications to improve or re-design their algorithms. In order to have confidence on correctness, performance and reliability of WAMC applications in real world scenarios, a pseudo-real test bed of whole WAMC system which mirrors the characteristic of both communication and power systems as real as possible seems to be required for designing/testing such applications. The purpose of this study is to put effort on proposing and developing a WAMC testing platform to facilitate the real time emulation of the dynamic power grid, the ICT infrastructure that overlays the grid and WAMS applications. The proposed platform consists of OPNET as a powerful communication simulator/emulator which is connected to Power Simulator (SIMULINK) on one side, and connected to end point stations such as PDC or application on the other side through OPNET’s real-simulation gateway called SITL. As an assessment to performance of developed platform architecture, different scenarios has been carried out to find out the effects of communication protocols i.e. UDP and TCP on network metrics such as data delay.
