Join the National Laboratory of the Rockies (NLR), where world-class scientists, engineers, and experts are accelerating energy innovation through breakthrough research and systems integration. From our mission to our collaborative culture, NLR stands out in the research community for its commitment to an affordable and secure energy future. Spanning foundational science to applied systems engineering and analysis, we focus on solving complex challenges to deliver advanced, secure, reliable, and cost-effective energy solutions. Our work helps strengthen U.S. industries, support job creation, and promote national economic growth.
At NLR, you'll find a mission-driven environment supported by state-of-the-art facilities, multidisciplinary research teams, and strong collaborations with industry, academia, and other national laboratories. We offer robust professional development opportunities, and a competitive benefits package designed to support your career and well-being.
Job Description
We are seeking a talented and motivated Power System Stability Analysis Engineer to join our team in a cutting-edge project focused on the stability analysis of power systems with a high penetration of Inverter-Based Resources (IBRs). As IBRs become increasingly prevalent, their integration into power grids presents unique challenges in grid stability, oscillation detection, and control. This project involves analyzing and interpreting real-time data from over 100 Phasor Measurement Units (PMUs) installed across the system to identify grid disturbances, detect oscillations, and assess system strength.
Job Responsibilities include but may not be limited to:

• Analyzing PMU data (from more than 100 PMUs) to monitor power system stability and detect grid disturbances
• Create visualizations of grid strength and stability based on PMU Data such as heat maps of grid inertia, voltage profile, equivalent short circuit ratio etc.
• Develop techniques that will improve the resilience and reliability of future power grids, particularly in systems dominated by IBRs
• Produce detailed reports on oscillation detection, system strength assessment, and grid stability findings
• Provide recommendations for mitigating potential stability risks
• Collaborate with power system engineers, control experts, and software developers to refine system models, improve analysis techniques, and support operational decision-making
• Contribute towards technical documentation and the generation of research papers
