Real Time Test Bed to Validate the Proposed RAS
In order to test the performance and analyze the communication requirement of RAS, this cyber-physical real-time is utilized. The architecture of the testbed is shown in the FigĀ \ref{fig:HardwareInLoop}.
In a simple test case, each simulated substation gets its own computation device (node), representing a real-time automation controller or substation PC. RTDS, simulating the grid network, is continually producing measurements for all buses selected at a substation. The measurements from the RTDS are obtained using GTNET PMU, which is one of the firmware supported in RTDS. The measurements from the GTNET PMUs are routed to a PDC, which in turn send the data to a communication network, emulated using ns-3 network simulator.
