Redwood Materials is seeking a Power Systems Engineer to design, develop, and validate control systems for battery energy storage solutions, ensuring compliance with utility and industry standards, and supporting grid integration and stability.
Key Responsibilities
Translate power system requirements into site and inverter controller specifications.
Design, develop, and validate plant controller functions for battery energy storage systems.
Ensure control algorithms comply with utility, ISO, and IEEE standards.
Build modeling capabilities for energy storage products in PSCAD and PSSE, including model validation.
Set up and execute CHIL testing on platforms like RTDS, OPAL-RT, or Typhoon HIL to validate inverter and controller performance.
Develop automation tools for interconnection studies using Python, C, or C.
Requirements
Work with the product and controls design teams to translate power system requirements into site controller and inverter controller specifications, influencing system and plant-level control architecture.
Design, develop, and validate plant controller functions for battery energy storage systems including voltage regulation, frequency regulation, P f and Q V droop control, active reactive power control loops, and fast frequency response.
Ensure control algorithms meet utility, ISO, and IEEE requirements including ERCOT interconnection specifications and IEEE 2800 compliance.
Build and strengthen in-house modeling capabilities for Redwood Energy’s products in PSCAD and PSSE, including model validation against field and controller-hardware-in-the-loop behaviors.
Set up and execute CHIL testing on platforms such as RTDS, OPAL-RT, or Typhoon HIL to validate inverter and site controller performance under grid disturbance and fault scenarios.
Develop automation tools for PSCAD and PSSE for interconnection studies using Python, C, or C.
MS or PhD in Electrical Engineering with specialization in power systems and control systems; PhD preferred.
Strong foundation in classical and modern control theory including PID tuning, state-space modeling, small-signal stability analysis, and frequency-domain analysis (Bode plots).
Expert proficiency in MATLAB Simulink for control algorithm development and testing.
Experience developing and validating user-defined inverter or plant controller models in PSCAD and/or PSSE.
Hands-on experience with inverter-based resource modeling including grid-forming and grid-following control, PLL design, virtual inertia, and droop-based power control.
Solid understanding of synchronous machine dynamics, excitation and governor systems, and system-level stability concepts such as frequency stability, voltage stability, and weak grid operation.
Experience with real-time simulation and CHIL environments such as RTDS, OPAL-RT, or Typhoon HIL.
Programming experience in Python, C, or C for model automation, controls integration, or testing workflows.
Experience performing or supporting transmission-level engineering studies such as transient stability, protection coordination, harmonics, and insulation coordination is a plus.
Familiarity working with utilities, ISOs, or renewable project developers is a plus.
Ability to perform the essential job functions safely and successfully in accordance with ADA, FMLA, and other federal, state, and local standards.
Ability to maintain regular, punctual attendance consistent with applicable standards.
Ability to work in challenging working conditions which may include exposure to noise, dust, chemicals, and temperature extremes, while protected by PPE.
Essential physical requirements such as climbing, standing, stooping, or typing.
Occasional work on weekends, nights, or being on-call as a regular part of the job.
