About this role
Leidos is a trusted and technology-focused solutions provider specializing in power delivery services. They are seeking a Senior Power System Engineer with expertise in renewable energy and data center integration to support transmission-level planning and system impact studies for utility-scale projects.
Responsibilities:
- Support large load and generation interconnection studies
- 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:
- O Large electronic loads (e.g., data centers)
- O PV, wind, and BESS resources
- Support development and integration of:
- O Solar/Wind/BESS Power Plant Controllers (PPCs)
- O Master Plant Controllers (MPCs)
- Lead RTDS / RSCAD CHIL testing (Control Hardware-in-the-Loop)
- Support microgrid design and control studies at MV and HV levels
- Participate in EPC HV/MV substation design studies for:
- O Large data center projects
- O Utility-scale PV, wind, and BESS projects
- 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)
- 5+ years of relevant experience in power systems planning and interconnection
- Strong experience in: PSCAD/RSCAD EMT modeling
- Experience embedding and coordinating PPC and MPC control strategies
- Experience with RTDS / RSCAD CHIL testing (Control Hardware-in-the-Loop)
- Demonstrated experience with: Large load interconnection studies (data center experience strongly preferred)
- Generation interconnection (PV, wind, BESS)
- Familiarity with NERC, FERC, ISO/RTO, TSP requirements for both generation and large load interconnections
- Professional Engineer (PE) license (preferred but not required)
