Description

  • Work with product and controls design teams to translate power system requirements into site controller and inverter controller specifications.
  • Influence system and plant-level control architecture.
  • Design, develop, and validate plant controller functions for battery energy storage systems.
  • Implement and tune voltage regulation, frequency regulation, P–f and Q–V droop control, active/reactive power 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.
  • Validate models against field behavior and controller hardware-in-the-loop behavior.
  • Set up and execute CHIL testing using real-time simulation platforms to validate inverter and site controller performance under grid disturbance and fault scenarios.
  • Develop automation tools for PSCAD and PSSE interconnection studies using Python, C, or C++.
  • Support transmission and interconnection engineering studies as needed.

Requirements

  • 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.
  • 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 is strongly preferred.
  • 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.

Benefits

  • California pay range of $145,200 to $255,000 USD.
  • Full-time position.
  • Compensation commensurate with experience.
