Responsibilities
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++
Qualification
Required
MS in Electrical Engineering with specialization in power systems and control systems
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 (frequency stability, voltage stability, weak grid operation)
Programming experience in Python, C, or C++ for model automation, controls integration, or testing workflows
Ability to perform the essential job functions consistent safely and successfully with the ADA, FMLA and other federal, state and local standards, including meeting qualitative and/or quantitative productivity standards
Ability to maintain regular, punctual attendance consistent with the ADA, FMLA and other federal, state, and local standards
Preferred
PhD in Electrical Engineering with specialization in power systems and control systems
Experience with real-time simulation and CHIL environments (RTDS, OPAL-RT, Typhoon HIL)
Experience performing or supporting transmission-level engineering studies such as transient stability, protection coordination, harmonics, and insulation coordination
Familiarity working with utilities, ISOs, or renewable project developers
