About the role#
The Grid Optimization and Control Group is seeking an intern to support the development of composite data center load models for transmission planning studies. This 6-12 month position focuses on building and validating both detailed EMT (electromagnetic transient) and RMS-based phasor models to represent the electrical architecture of modern data centers. This work directly contributes to improving reliability, stability, and protection strategies for transmission systems.
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.
- 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.
What you'll need#
- Completed an undergraduate degree in power systems, electrical engineering, or a related field.
- Current enrollment in or recent graduation from a master's or PhD program in a relevant field.
- Minimum of a 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 in Python, MATLAB, or similar tools.
- Experience with EMT simulation tools such as PSCAD or EMTP.
- Strong communication and technical writing skills.
- Demonstrated knowledge or experience with phasor-domain tools such as PSS®E or PSLF is preferred.
Location & details#
- Location: Golden, Colorado.
- Modality: Remote and on-site options available.
- Schedule: Full-time (40 hours per week).
- Employment: Paid, fixed-term internship.
- Requirements: All candidates must be authorized to access the facility per Department of Energy rules and must be able to obtain and maintain a federal Personal Identity Verification (PIV) card, which includes a background investigation. Employment is contingent upon passing a pre-employment drug test.
