WIRAB Webinar Series (Webinar #4): Short-Term Reliability (Part 2) – Transient and Small Signal Stability


The Western Interconnection Regional Advisory Body (WIRAB) hosted a series of five tutorials on how the changing resource mix affects grid reliability. Power system experts Debbie Lew and Nick Miller broke down grid reliability needs into long-term, medium-term, and short-term timeframes to discuss how to consider grid reliability with the changing grid. Although the subject matter is technical, these tutorials were designed to be understood by a non-technical audience such as regulators and policymakers.

Webinar #4:  Short-Term Reliability (Part 2) – Transient and Small Signal Stability

Wednesday, May 6, 2020, at 2:00 PM MT (1 Hr)

Transient stability refers to the grid’s ability to reach a stable condition following a large disturbance in the system. Small signal stability refers to the power system’s ability to reach its stable condition after small disturbances like minor fluctuations in load and generation.

Questions to consider for short-term reliability include:

  • How do inverter-based resources lead to weak grids, and what are the implications of weak grid systems?
  • What can we do to mitigate these issues?
