Principal Engineer, Advanced Energy System Controls
Job Description:
- Own and lead development of integrated controls architectures for multi-resource power systems combining solar PV, battery energy storage, fuel cells, synchronous generation, utility sources, switchgear, protection systems, and co-located critical customer loads
- Develop control philosophies, functional design specifications, control-authority matrices, operating-mode definitions, sequence-of-events narratives, permissives, interlocks, fallback modes, and fail-safe behaviors
- Define hierarchy and coordination among device controls, inverter controls, generator governors and excitation systems, PPC, microgrid controllers, EMS, SCADA, protection relays, and customer or utility interfaces
- Lead operating modes and transitions including grid-connected operation, islanded operation, planned and unplanned islanding, energization, synchronization, resynchronization, and system black start
- Support technical reviews of controls drawings, network and communications diagrams, I/O lists, and interface-control documents
- Develop controls architecture integrating data center loads with utility-scale generation and battery energy storage systems
- Develop load-following and dispatch algorithms for rapid data center load changes and coordinate BESS response with slower generation resources
- Develop operating sequences for grid-connected operation, islanding, load rejection, black start, restoration, and data center load pickup
- Lead integrated validation through EMT studies, real-time controls testing, and site commissioning
- Develop multi-resource dispatch strategies, EMS control strategies, BESS state-of-charge management, reserve management, and flexible interconnection controls
- Lead advanced control-algorithm development and validation using predictive, feedforward, feedback, droop-based, and optimization-based methods
- Define EMT study requirements; review PSCAD models, methodologies, and results; and guide follow-on simulations and tuning studies
- Lead integrated controls validation at vendor facilities and AES laboratories using CHIL, PHIL, and real-time test platforms
- Lead testing across resource controllers, PPC, EMS, SCADA, protection, and microgrid controls, including operating modes, transitions, failure scenarios, communications loss, and recovery behavior
- Define instrumentation and high-speed data acquisition requirements and drive test findings through technical resolution
- Serve as principal technical advisor and design-review authority for complex control architectures, first-of-kind applications, vendor proposals, software releases, and technical deviations
- Lead multidisciplinary technical reviews and facilitate decisions across controls, electrical, protection, generator modeling, and commissioning stakeholders
- Mentor engineers without requiring direct supervisory responsibility
- Communicate complex issues to technical, project, customer, and executive audiences
- Monitor technology developments and evaluate emerging control architectures, microgrid controllers, grid-forming platforms, dispatch approaches, communications architectures, and real-time validation methods
Requirements:
- Master’s degree in controls engineering, power systems engineering, energy systems, electrical engineering, or a related field
- Typically 8 to 12 years of experience in utility scale power systems controls, microgrids, utility-scale generation, energy storage, or advanced control applications
- Demonstrated experience in system controls integration with colocated loads and utility scale generation and energy storage projects strongly preferred
- Deep understanding of grid-connected and islanded power systems, microgrid controls, grid-forming controls, synchronous generation, BESS, and renewable generation
- Experience developing control architectures, control philosophies, sequences of operation, operating modes, and advanced system-control algorithms
- Experience with EMS, PPC, microgrid controllers, SCADA, and resource-level controls for integrated multi-resource power systems
- Strong knowledge of multi-resource dispatch, BESS state-of-charge management, load following, load smoothing, reserve management, and flexible interconnection controls
- Working knowledge of PSCAD and EMT analysis, with particular experience reviewing models and simulation results for control interactions and system performance
- Experience developing and leading CHIL, PHIL, factory, laboratory, and integrated system testing for complex power-system controls
- Knowledge of industrial communications, controls drawings, high-speed data acquisition, and protocols such as Modbus, DNP3, and IEC 61850
- Field experience with system integration, commissioning, controls troubleshooting, and first-of-kind power systems involving multiple OEMs and technology partners
- PhD preferred
Benefits:
