Leidos is a trusted, technology-focused solutions provider delivering power and telecommunications expertise through its Power Delivery Services Team. The Senior Power System Engineer will support transmission-level planning, interconnection studies, dynamic modeling, and EPC design for utility-scale renewable projects and hyperscale data center developments, particularly within the ERCOT market.

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 PSSE 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
