Electric Power Research
Published Research:
In support of ICASA’s mission to solve critical infrastructure protection problems, the Electric Power team focused on two research areas: 1) understanding fundamental behavior and vulnerabilities between power system components as they interact through the network, and 2) developing means by which precursors to large failures can be detected and their impact mitigated. Key elements of this research were modeling and simulation of electric power systems as hybrid dynamical systems, and analysis methods founded in control and systems theory.
