Principal Power Systems Engineer

Overview

Create and validate BESS dynamic models, ensure grid compliance, and support customers.

Key Responsibilities

• bess integration
• model development
• simulation runs
• tool development
• commissioning support
• compliance docs

Tasks

-Perform integration of BESS with renewable assets (e.g., PV and wind) and conduct hybrid plant dynamic assessments. -Identify lessons learned from customer projects and contribute to updates in design guidelines and best practices. -Optimize control and protection model parameters to meet grid stability, voltage, and frequency response criteria. -Act as the technical authority on behalf of Wärtsilä with key customers—including project developers, utilities, and network service providers (NSPs)—in the APAC region, particularly Australia. -Supporting commissioning engineers during R2 validation and site testing to ensure model-to-field alignment. -Coordinate with internal and external stakeholders during R2 testing and post-commissioning verification. -Translate simulation algorithms into practical software modules in Python or Fortran for automated workflows. -Collaborating with grid compliance engineers, software developers, and project managers to align technical deliverables. -Engaging in internal technical reviews and contributing to tool development or automation scripts for grid modeling and compliance tracking. -Act as a bridge between the customer, internal modelling/software/hardware teams and regulatory/NSP stakeholders: diagnosing issues, proposing workarounds, and ensuring customer deliverables (e.g., simulation packages, hold-point test results) are met on time and to spec. -Maintain strong relationships with customers during all project phases (feasibility → design → commissioning → operation), ensuring the modelling and grid compliance work translates into smooth execution, handover and operations. -Provide training and mentoring to internal teams and customers on grid connection processes and simulation practices. -Support pre-sales and proposal activities: collaborate with business development and project teams to craft technical solutions, respond to customer RFIs/RFPs, and present modelling/controls strategy to clients. -Enhance internal modeling tools and compliance workflows to improve speed, accuracy, and standardization across projects. -Provide training and knowledge transfer for customers or their engineering teams on model assumptions, performance criteria, and compliance obligations. -Support GPS packages by preparing compliance documentation, including performance studies, test procedures, and validation reports. -Participating in technical calls with AEMO, NSPs, and project developers to resolve compliance or modeling issues. -Running and analyzing PSCAD and PSS®E simulations to validate dynamic model performance against GPS criteria. -Preparing simulation reports, test plans, and grid compliance documentation for active projects. -Maintain up-to-date knowledge of AEMO and Australian Standards, including NER S5.2.5, S5.2.6, and related compliance clauses. -Reviewing and responding to customer technical inquiries and supporting GPS process milestones (R0 → R1 → R2). -Develop, validate, and maintain dynamic simulation models of Wärtsilä BESS in tools such as PSCAD, PSS®E, and DIgSILENT PowerFactory.
