Fault Recovery Analysis

Prescient has experience crafting bifurcated analysis models to evaluate the resiliency of the grid after a fault has cleared.

Why Use Our Services?

Since the 1960s, electric utilities have used computer-based transient stability models to determine if the electric power grid would stabilize or collapse after faults are cleared. The results of these studies provide a reasonable assessment of the ability of large, central generating stations to remain synchronized to the power grid. However, these studies do not account for renewable energy sources, which have been designed with different performance characteristics than central generating stations. They also do not account for customer loads of the future.

With state-of-the-art technology, the effectiveness of transient stability studies can be increased ten-fold, and the likelihood of wide area blackouts caused by faults on the power grid can be eliminated. The key is to develop bifurcated models of the power grid – a steady state model and a voltage sensitive transient model.

Prescient provides bifurcated analysis models to ensure that renewable and traditional energy sources are assessed for grid stability. Contact us to learn more.

Description of Services

Prescient’s technical staff will analyze customer loads to assure dynamic load changes are understood. We will then develop bifurcated models that represent dynamic system conditions and estimate system recovery time in seconds.
