Completed Projects

Thrust 1

Through fire risk modeling and grid simulation, we will help utilities plan for and mitigate a disaster from fire and identify grid response strategies and resilient designs that reduce vulnerability leveraging past work on cascading failures.

Better risk characterization and prioritization of ICS threats. ADROC will be a useful platform to test and evaluate cyber threat mitigation technologies proposed under RES.

This project will create a methodology for modeling
components or structures in an electrical system.
These models will be used for relating system
level events to insults arriving at specific pieces of
critical equipment.

Thrust 2

This project focuses on the development a novel circuit architecture to render AC–AC solid-state transformers (SSTs) competitive in real-world applications, and an analysis of how second generation AC–DC AC SSTs can address the problem of cascaded electrical outages.

Sandia’s “lowmodulation-
index 3-phase solid-state transformer
(LMI3-SST)” technology is intended to address current
obstacles to wide-spread adoption and provide the
first commercially viable SST circuit topology.

HARMONIE-SPS will improve grid resilience by extending protection capabilities to defend against a wide range of cyber-physical disturbances.

Novel approach to increase distribution system resiliency by improving protection system accuracy and speed; advanced modeling and evaluation in KAFB DC micro grid.

Thrust 3

Develop enhanced optimization techniques to incorporate intentional threats, and leverage successes in network diffusion modeling (NDM) to capture grid behaviors at higher levels of abstraction.

Develop novel stochastic resilience optimization with hybrid dynamic constraints.

Develop the capabilities to identify electric grid critical nodes and their vulnerability levels to physical attack and EMP using advanced interdiction models, verified against dynamic cascading failure models, and to develop a multi-stage topology optimization model, informed by node criticality to improve resilience.
