Key Responsibilities

The System Study & Modeling Engineer is responsible for developing, validating, and executing electrical system models and studies to assess the performance, stability, and compliance of power and energy systems. This role supports project development, detailed engineering, and grid interconnection by providing analytical insight into system behavior across steady‑state and dynamic operating conditions.

The position serves as a technical bridge between system architecture, control design, and grid requirements, ensuring designs are technically sound, standards‑compliant, and deployment‑ready.

Main Accountabilities

• Develop and maintain accurate system‑level electrical models for power plants, microgrids, and energy systems.
• Execute grid interconnection and performance studies to support regulatory, utility, and customer requirements.
• Assess system behavior under normal, transient, and fault conditions.
• Provide analytical input to system architecture, control strategy, and equipment sizing decisions.
• Ensure study methods, assumptions, and results are technically defensible and traceable.
• Support internal design reviews and external stakeholder engagements (utilities, ISOs, consultants).
  
  

Key Activities And Responsibilities

• Develop electrical system models including:
• Generation, BESS, inverter‑based resources
• Loads, transformers, protection devices
• Utility grid representations
• Build and maintain models in tools such as:
• PSCAD / EMTDC
• PSS®E, PowerFactory, or equivalent
• MATLAB/Simulink or similar platforms
• Ensure alignment between study models and:
• Control design assumptions
• Equipment ratings and settings
• One‑line diagrams and protection philosophies
  
  

Minimum Qualifications

• Perform and support studies including:
• Load flow and voltage regulation analysis
• Short‑circuit and fault duty analysis
• Dynamic and transient stability studies
• Frequency response and inertia analysis
• Harmonics and power quality studies
• Islanding, black‑start, and ride‑through performance
• Support grid interconnection requests and processes.
• Perform studies aligned with standards and grid codes such as:
• IEEE 1547 / 1547.1
• Utility‑specific interconnection requirements
• Relevant IEC or regional grid codes
• Prepare technical documentation and study reports for:
• Utility submission
• Internal design validation
• Customer and third‑party review
• Strong fundamentals in:
• Power system analysis
• Electrical machines and inverter‑based resources
• Dynamic and steady‑state system behavior
• Hands‑on experience with industry power system simulation tools.
• Ability to interpret:
• Electrical one‑line diagrams
• Control and protection philosophies
• Equipment datasheets and interconnection requirements
• Solid understanding of utility‑connected and islanded power systems.
  

Soft Skills & Behavioral Competencies

• Systems thinker – able to balance control performance, hardware limits, grid requirements, and operational constraints.
• Structured problem solver – approaches complex technical problems methodically and transparently.
• Technical communicator – can clearly explain control concepts to non‑controls experts, customers, and leadership.
• Collaborative mindset – works effectively across disciplines and organizational boundaries.
• Ownership & accountability – takes responsibility for technical outcomes from concept through deployment.
• Adaptability – comfortable working in evolving architectures and handling ambiguous requirements.
• Attention to detail – maintains rigor in documentation, testing, and validation.
  
  

Preferred Qualifications

• Experience with microgrid controllers, EMS, or plant‑level supervisory controls.
• Exposure to utility interconnection processes and grid code compliance.
