Research on Intentional Controlled Islanding in Power Systems: A Proactive Approach to Prevent Cascading Failures

Location: Burchard 102
Speaker: Jingfeng Fu, Visiting Scholar, ECE Department, Stevens
ABSTRACT
Cascading failures in power systems can lead to large-scale blackouts, as seen in the 2021 Texas winter storm and the 2023 Brazil blackout. Traditional out-of-step islanding methods rely on local measurements and split the grid where oscillations are detected, rather than where it is optimal for system stability. This presentation introduces Intentional Controlled Islanding (ICI) as a proactive defense approach that determines optimal splitting boundaries to ensure each resulting island maintains power balance and frequency stability. A Mixed Integer Linear Programming (MILP) model is formulated to optimize splitting boundaries while satisfying generator coherency constraints, connectivity requirements, and power balance conditions. Simulation results on the IEEE 39-bus system validate the effectiveness of the proposed strategy.
