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

About the role#

The Grid Optimization and Control Group is seeking a graduate intern for a 6-12 month project focused on data center load modeling for transmission planning studies. This role involves developing and validating both electromagnetic transient (EMT) and RMS-based phasor models to represent the electrical architecture of modern data centers. You will contribute to improving reliability, stability, and protection strategies for transmission systems as data centers continue to grow as critical grid loads.

What you'll do#

• 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 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 to capture fast transients and fault behavior.
• Build corresponding RMS phasor models for transmission planning tools 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 and contribute to technical reports and research papers.

What you'll need#

• Completed an undergraduate degree in power systems, electrical engineering, or a related field.
• Current enrollment in a master’s degree program or PhD program in a relevant field, or graduation from such a program within the past 12 months.
• Minimum 3.0 cumulative grade point average.
• Demonstrated knowledge and experience with power electronics, machines, drives, dynamic load modeling, and power system stability.
• Strong programming and analytical skills using Python, MATLAB, or similar tools.
• Experience with EMT simulation tools such as PSCAD or EMTP.
• Strong communication and technical writing skills.
• Experience with phasor-domain tools such as PSS®E or PSLF is preferred.

Location & details#

• Location: Golden, Colorado.
• Term: 6-12 month internship.
• Modality: Remote and on-site work.
• Employment: Full-time (40 hours per week).
• Note: This position is subject to Department of Energy access restrictions and requires the ability to obtain and maintain a federal Personal Identity Verification (PIV) card. A pre-employment drug test is required.
