Senior Power System Engineer - Renewable & Data Center Integration

Leidos is a trusted and technology-focused solutions provider, seeking a Senior Power System Engineer with expertise in large load and renewable interconnections. The role involves supporting transmission-level planning, system impact studies, and EPC design efforts for utility-scale renewable projects and hyperscale data center developments.

Responsibilities:

• Lead and support large load and generation interconnection studies in ERCOT and other transmission systems
• Apply and interpret NERC, FERC, ISO/RTO, TSP requirements for both generation and large load interconnections
• Develop and validate steady state models in ETAP and PSSE, and dynamic models in PSS®E and PSCAD for:
• Large electronic loads (e.g., data centers)
• PV, wind, and BESS resources
• Support development and integration of:
• Solar/Wind/BESS Power Plant Controllers (PPCs)
• Master Plant Controllers (MPCs)
• Participate in EPC HV/MV substation design studies for:
• Large data center projects
• Utility-scale PV, wind, and BESS projects
• Support or lead microgrid design and control studies at MV and HV levels
• Support RTDS / RSCAD CHIL testing (Control Hardware-in-the-Loop)
• Interface with Transmission Service Providers (TSPs), ISO/RTOs (especially ERCOT), developers, OEMs, and project stakeholders
• Perform steady-state and short-circuit analyses including: Load flow studies, Short circuit analysis, Protection coordination, Arc-flash studies, Reactive power and energy loss analysis, and Harmonic studies
• Conduct electromagnetic transient (EMT) studies in PSCAD, including: Transient overvoltage (TOV), Transient recovery voltage (TRV), Insulation coordination, SSR/SSO screening and mitigation analysis

Requirements:

• Bachelor's or Master's degree in Electrical Engineering (Power Systems preferred)
• 8+ years of relevant experience in power systems planning and interconnection
• Strong experience in: PSS®E dynamic modeling and analysis, PSCAD EMT modeling, ETAP steady-state and protection studies
• Demonstrated experience with: Large load interconnection studies (data center experience strongly preferred), ERCOT transmission planning and compliance requirements, Generation interconnection (PV, wind, BESS)
• Experience developing dynamic PSSE and PSCAD models for large inverter-based resources and electronic loads
• Familiarity with NERC, FERC, ISO/RTO, TSP requirements for both generation and large load interconnections
• Experience embedding and coordinating PPC and MPC control strategies
• Experience with RTDS / RSCAD CHIL testing (Control Hardware-in-the-Loop)
• Professional Engineer (PE) license (preferred but not required)
