Electrical Grid Resiliency Via Solid-State Transformer Technology

Karina Munoz-Ramos Factsheet

Project Overview:

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 secondgeneration AC–DC–AC SSTs can address the problem of cascaded electrical outages. R&D activities span advanced modeling of the stabilizing effect of AC–DC–AC SSTs on the electrical grid, design and testing novel AC–AC SST circuit architectures subject to stringent efficiency and electromagnetic interference requirements, and independent thirdparty technoeconomic analysis of Sandia’s proposed AC–AC SST architecture.
