Aditya Rangarajan

I am working towards a PhD degree with an interest in modelling and analysis of power systems. I am interested in understanding the drawbacks of existing power system protection standards and the impact of operational uncertainty on them. I am currently working on methods to better design protection schemes for bulk power systems and to increase their robustness against variability in loads and renewable generation. In addition, I am also collaborating with other graduate students to develop a geographically accurate synthetic grid for geo-referenced applications.

Optimal Design of Remedial Action Schemes

Remedial Action Schemes (RAS) are automatic protection systems that detect abnormal system conditions and take predetermined and fast control actions. This work tries to address some of the deficiencies in existing methods to design Remedial Action schemes by proposing an optimization framework to choose optimal emergency actions in response to a set of contingencies.

California Test System (CATS): A Geographically Accurate Synthetic Test System based on the California Grid

The synthetic grid was created using GIS data for California’s transmission lines, which is publicly available from the California Energy Commission.

Many synthetic grids do not reflect the real locations and paths of electric infrastructure due to security concerns. However, accurate geography is important for geo-referenced applications, including studies related to climate, topography, natural resources, and energy justice. Sofia Taylor, Jonathan Snodgrass, and Noah Rhodes, and Aditya Rangarajan are developing the California Test System (CATS), which is a geographically accurate synthetic grid, by combining publicly available locational data for California’s electric infrastructure with parameters that are realistic but not real.
