About The Position

The Senior Power Systems Modeling Engineer leads the development, validation, and deployment of advanced electrical grid models that capture the behavior of utility‑scale and distributed storage assets.

Requirements

• Proficiency with PSCAD, PSS®E, PSLF, DIgSILENT PowerFactory, or equivalent simulation tools.
• Strong understanding of inverter controls, dynamic stability, EMT phenomena, and grid‑code compliance.
• Programming experience in Python, MATLAB, or similar languages for automation and data processing
• Experience with grid forming inverter modeling and advanced control strategies.
• Familiarity with NERC PRC standards, FERC Order 841/2222 implications, and ISO/RTO interconnection processes.
• Knowledge of hybrid plant modeling (solar + storage, wind + storage).
• Experience working with BESS OEMs, EPCs, or utilities on model validation and commissioning.
• Bachelor's degree in electrical engineering required
• Minimum of 8 years' experience.

Nice To Haves

• master's preferred

Responsibilities

• Build and validate steady‑state, dynamic, and EMT models of battery energy storage systems, power electronic converters including inverter‑based resources in grid forming / grid following modes, plant controllers, rotating machines and other power system components like transformers, power factor correction equipment etc.
• Conduct interconnection studies for BESS projects: load flow, short‑circuit, transient stability, protection coordination, and harmonic analysis.
• Evaluate BESS performance under grid disturbances, including frequency response, voltage support, ride‑through, and black‑start capabilities.
• Model and analyze BESS control strategies, including active/reactive power control, droop control, state‑of‑charge management, and hybrid plant coordination (e.g. solar + storage).
• Assess impacts of BESS on system stability, congestion, hosting capacity, and renewable integration.
• Support development and validation of plant‑level controllers, including AGC participation, grid‑forming controls, and advanced inverter functions
• Lead creation of modeling pipelines that integrate SCADA, GIS, EMS, and OEM data into simulation environments.
• Develop automation scripts in Python, MATLAB, or C# to streamline model validation, scenario generation, and reporting.
• Troubleshoot complex model behavior and ensure alignment with IEEE, IEC, UL 9540/9540A, and regional interconnection requirements
