Cascades Platform

Cascades Platform

Cascades provides a platform for power system risk analyses and expansion planning. The objectives of Cascades are to perform: (I) cascading failure simulations; and (II) vulnerability analyses (III) risk-informed transmission system expansion planning. Cascades comprise two core models for cascading failure analyses, i.e., DC and AC based. Furthermore, the cascading failure models can be used on single or multi-zonal large power systems. Moreover, the cascading failure simulations are validated/calibrated using historical blackout data. The Cascades module comprises of four integral parts:

  1. A cascading failure simulations models (AC and DC);
  2. Vulnerability analyses method;
  3. Transmission system expansion planning method;
  4. Method for calibration of the cascading failure models.
