ROLE SUMMARY
The Senior Power Systems Modeling Engineer is technical owner for power system modeling model validation and grid performance assessment. This role sets modeling standards leads high-impact simulation work and ensures models accurately represent hardware controls firmware protection settings and plant-level operating modes.

The position supports product development interconnection studies grid requirements demonstrations customer projects and emerging large-load applications. It serves as a key technical bridge across R&D Controls Test Product Project Engineering external consultants customers utilities ISOs and standards organizations.

Key focus areas include EMT and dynamic modeling ERCOT Model Quality Testing evolving large-load ride-through requirements hardware-to-model matching Hardware-in-the-Loop and real-time simulation and project-specific modeling support for deployments.

RESPONSIBILITIES

• Define modeling standards: Establish modeling philosophy validation methods governance processes and quality expectations across EMT RMS transient steady-state HIL and real-time simulation environments.
• Own model lifecycle management: Ensure models remain aligned with released hardware firmware controls algorithms protection settings plant controls and project-specific configurations.
• Serve as technical authority: Provide expert judgment on model fidelity validation evidence simulation assumptions and external model submissions.

• Lead technical execution: Develop review and approve EMT and dynamic models supporting interconnection studies customer applications product qualification and grid requirements.
• Support project modeling: Partner with Project Engineering on study assumptions equivalent models SLD representation equipment settings operating conditions and data requirements.
• Assess system performance: Evaluate ride-through behavior weak-grid performance harmonics generator interations startup behavior control response and large-disturbance response.

• Ensure hardware-to-model alignment: Confirm models represent inverter behavior BESS response EMS functionality firmware protection controls and fielded product configurations.
• Correlate models with evidence: Compare simulations against lab tests HIL results commissioning data field measurements disturbance records and vendor model behavior.

• Lead grid requirements modeling: Serve as technical lead for ISO MQT large-load ride-through evaluations and evolving grid requirements.
• Oversee external studies: Direct and review work performed by consultants and study partners ensuring technical quality traceability and consistency with standards.
• Influence product and engineering direction: Translate modeling insights into recommendations for controls firmware hardware design validation investments customer applications and roadmap priorities.
• Mentor and represent: Guide engineers across modeling controls test and project teams and represent in technical discussions with utilities ISOs consultants customers and industry groups.

EXPERIENCE AND REQUIREMENTS
