ABSTRACT:
Massive integration of power electronic devices including inverter-based resources (IBRs) into power systems has significantly prompted electromagnetic transient (EMT) simulation for great insight. An RTDS simulator offers a tremendous simulation advantage over its offline EMT counterparts by incorporating external equipment for real-time hardware-in-the-loop testing. This presentation demonstrates that RTDS simulators can run real-time simulations concurrently with phasor-domain transient stability analysis tools. As a result, hardware-in-the-loop simulation can be carried out in the context of large-scale power system planning, scheduling, and operation. The IEEE 39-Bus System and a real case with over 5000 buses are used as two benchmarks to illustrate procedures to perform real-time power system study using both RTDS and the transient stability analysis tool TSAT. Results show that with the RTDS simulator being able to simulate in conjunction with another tool, more comprehensive evaluations can be made based on both system- and device-level details that are subsequently revealed in different domains. In particular, due to the ability of RTDS simulators to deploy detailed models including but not limited to HVDC, FACTS, and IBRs, the hybrid simulation has wide applicability to satisfy various purposes in the power sector.
