Job Description

The National Laboratory of the Rockies (NLR) is seeking a motivated Power System Planning Intern to join the Grid Planning and Analysis Center (GPAC) within the Strategic Energy Analysis and Decision Sciences (SEADS) directorate. SEADS leads cutting-edge energy analysis and grid research, applying advanced modeling and simulation to design, plan, and optimize distribution and bulk power systems, with a focused emphasis on improving the reliability, resilience, and affordability of the power system.

As part of GPAC, you’ll support applied research in electric power systems planning by utilizing integrated planning modeling techniques that include power-flow modeling, dynamic modeling, and optimized distribution and bulk power systems, with a focused emphasis on improving the reliability, and resilience of the power system. This work aims to address challenges posed by a high percentage of Inverter-Based Resources (IBRs) and Distributed Energy Resources (DER), and to prioritize investments that enhance grid reliability and resilience.

Key Responsibilities:

• Run simulations and analyze data for large-scale power system models

• Develop modeling and analysis tools, optimization formulation, dynamic simulation techniques, and co-simulation frameworks, as well as clear, compelling visualizations to communicate research findings.

• Build and validate large-scale power system models, specifically focusing on dynamic and steady-state generation, transmission, and distribution models.

• Contribute to reliability studies, including examining interactions between DER and bulk grid dynamics, and the impacts of natural hazards on distribution assets.

• Build tools to pull, clean, process, and integrate diverse datasets into existing workflows.

• Strengthen GPAC’s capabilities in transmission and distribution planning, data center integration, and dynamic/reliability analysis through data processing and visualization.

• Contribute to ongoing projects by delivering technically rigorous and accessible insights for stakeholders.

• Follow all Environment, Safety, and Health policies and procedures to maintain a safe working environment.
