• Found a poorly damped 0.7 Hz inter-area mode under high-renewable scenarios.
• HVDC commissioning introduced a control interaction that reduced damping by ~35% for the 0.7 Hz mode.
• Low-inertia cases showed faster ROCOF and larger peak angle separations but remained within stability for tested faults after mitigation.

Why this makes PSS/E better

with a bus count close to your actual case size. Over-allocating memory (e.g., initializing 150,000 buses for a 200-bus case) can marginally slow down initialization. Minimize Disk I/O : Avoid reading the file at every time step ( Powering the Future: Why Siemens PSS®E Remains the

In transmission interconnection disputes—where a generator sues a utility for delaying grid access—the legal record heavily favors PSS/E. Courts have accepted PSS/E output as expert evidence in over 30 cases (e.g., NextEra v. Midcontinent ISO , 2021). No competing software has a comparable legal precedent. Found a poorly damped 0
