Worked on NREL-Sienna/PowerSimulations.jl and NREL-Sienna/PowerSystems.jl, delivering two targeted features over two months. Developed AC power flow loss factor support by integrating auxiliary variables into flow evaluation, enabling conditional inclusion through a configuration option and improving data consistency by writing voltage angle and magnitude back to PowerFlowData after OPF. Enhanced CI/CD workflows in PowerSystems.jl by expanding the cross-package test matrix to include PowerFlows, automating compatibility checks and reducing manual testing. Leveraged Julia and YAML for API design, numerical simulation, and testing, focusing on robust integration and operational efficiency across power systems analysis and software development workflows.
