Graduate (6-12 month) Intern - Data Center Load Modeling for Transmission Planning Studies

About the role

The Grid Optimization and Control Group at the National Laboratory of the Rockies (NLR) is seeking a highly motivated intern to support the development of composite data center load models for transmission planning studies.

Responsibilities

• Gather and analyze technical data on data center electrical architecture, including UPS systems, PDUs, cooling systems, and backup generation
• Develop and validate component-level models (e.g., UPS with PFC, PDU, VFD), and build a composite data center load model that integrates IT load, power electronic interfaces, and motor-driven auxiliaries
• Implement detailed EMT models in simulation platforms (e.g., PSCAD, RTDS) to capture fast transients and fault behavior
• Validate the EMT models using real-world data
• Build corresponding RMS phasor models for transmission planning tools (e.g., PSS®E, and PSLF) to enable computationally efficient studies
• Perform side-by-side comparisons between EMT and RMS models to assess accuracy and applicability for different planning scenarios
• Document modeling methods, assumptions, and validation results in a clear and reproducible format
• Collaborate with planning and protection engineers to ensure models meet practical study requirements
• Contribute to the development of technical reports and research papers

Requirements

• Minimum of a 3.0 cumulative grade point average
• Undergraduate: Must be enrolled as a full-time student in a bachelor’s degree program from an accredited institution
• Post Undergraduate: Earned a bachelor’s degree within the past 12 months
• Graduate: Must be enrolled as a full-time student in a master’s degree program from an accredited institution
• Post Graduate: Earned a master’s degree within the past 12 months
• Completed an undergraduate degree in power systems, electrical engineering, or related field, and be pursuing or graduated from a master's degree, or currently enrolled in a PhD program in these fields
• Demonstrated knowledge and experience with power electronics, machine and drives, dynamic load modeling, and power system stability
• Experience with EMT simulation tools (e.g., PSCAD or EMTP)
• Strong programming/analytical skills (Python, MATLAB, or similar)
• Strong communication and technical writing skills

Qualifications

• Completed a master’s degree within the past 12 months
• Completed a bachelor’s degree within the past 12 months
• Completed a PhD program within the past 12 months

Skills

• Knowledge of phasor-domain tools (e.g., PSS®E, PSLF) is preferred
• Knowledge and experience with power electronics, machine and drives, dynamic load modeling, and power system stability

Benefits

• Medical, dental, and vision insurance
• 403(b) Employee Savings Plan with employer match*
• Sick leave (where required by law)

Pay

$44,500 - $71,200 annually

Schedule

Less than 20 hours per week
