Key Responsibilities

  • · Develop, review, and validate EMT, RMS, steady-state, and PPC models for BESS, inverters, plant controllers, and company applications.
  • · Work with inverter vendors across multiple time zones to obtain models, verify completeness, test performance, and close model gaps.
  • · Integrate inverter and plant-controller models with company PPC models and create complete model packages for project and study use.
  • · Perform and review studies for fault ride-through, voltage and frequency response, reactive power capability, weak-grid behavior, control interactions, and grid-code compliance.
  • · Create and update PPC models, control block logic diagrams, model documentation, simulation reports, and compliance evidence.
  • · Coordinate with internal grid modeling teams to ensure models follow company modeling guidelines and quality standards.
  • · Support external modeling firms by clarifying model assumptions, resolving technical questions, and enabling timely study completion.
  • · Track evolving grid-code and modeling requirements from grid operators and utilities and update models as needed to maintain compliance.
  • · Use Jira, email, meetings, and direct technical engagement to obtain support, resolve blockers, and keep modeling deliverables progressing.
  • · Communicate technical findings professionally with OEMs, consultants, utilities, grid operators, customers, and internal stakeholders.
  • · Support new BESS applications, including data centers, GFM, Black Start, island operation, and other advanced control use cases.
  • · Travel to project sites and vendor factories as needed for model validation, technical workshops, FAT support, or project execution.

Required Qualifications

  • · Bachelor’s degree in Electrical Engineering, Power Systems, Power Electronics, Controls, or related field.
  • · 7+ years of experience in power systems, BESS, inverter-based resources, grid interconnection, or power-system modeling.

  • · Proficiency with PSCAD/EMTDC, PSS®E, PowerFactory, MATLAB/Simulink, PSLF, TSAT, ETAP, or similar tools.
  • · Strong understanding of inverter controls, plant controllers, grid-code compliance, model validation, and utility interconnection requirements.
  • · Ability to test models, identify gaps, challenge assumptions, and prevent incomplete model packages from moving forward.
  • · Excellent communication and interpersonal skills, including professional technical emails and the ability to influence cross-functional support without direct authority.
  • · Experience using Jira or similar tools to manage modeling issues, technical blockers, owners, and closure status.
  • · Ability to coordinate across OEMs, modeling firms, utilities, grid operators, customers, and internal engineering teams.
  • · Valid work authorization and ability to obtain or maintain required visas for international travel to project sites, customer locations, and vendor factories.
