WIRAB Webinar Series (Webinar #3): Short-Term Reliability – System Stability Introduction and Frequency Response


WIRAB Webinar Series – Grid Reliability and the Changing Resource Mix

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.

Short-Term Reliability – System Stability (Two Sessions)

Short-term reliability is ensuring frequency, transient, and small-signal stability. PV, wind, and batteries connect to the grid through an inverter, which responds to grid events differently than conventional generators. This subject matter is the most technical of all the tutorials, but it is still intended for a non-engineering audience.

Introduction and Frequency Response (Session 1)

Wednesday, April 29 at 2:00 PM MT (1 Hr)

Frequency response refers to the power system’s ability to recover from the loss of generation. Inverter-based resources do not provide inertia that helps the grid recover from these events. How will a low inertia system operate, and how can inverter-based resources help?
