Job Description
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.
- Occasional travel requirements.
