Job Description

The Power Systems Engineer, Energy Storage, is responsible for designing, developing, and validating control systems for battery energy storage solutions, ensuring compliance with utility and industry standards, and supporting modeling and testing activities to optimize 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 and validate modeling capabilities for energy storage products in PSCAD and PSSE.
Set up and execute CHIL testing to validate inverter and controller performance under grid disturbances.
Develop automation tools for interconnection studies using Python, C, or C++.

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 (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
Ability to work with control algorithms to meet utility, ISO, and IEEE requirements including ERCOT interconnection specifications and IEEE 2800 compliance
Experience setting up and executing 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
Ability to build and strengthen in-house modeling capabilities for energy storage products in PSCAD and PSSE, including model validation against field and hardware-in-the-loop behaviors
Experience developing automation tools for PSCAD and PSSE for interconnection studies using Python, C, or C++
Experience supporting transmission-level engineering studies such as transient stability, protection coordination, harmonics, and insulation coordination (preferred but not mandatory)
