Responsibilities
EMT modelling and simulation
- Perform electromagnetic transient (EMT) studies using PSCAD, including HVDC systems, renewable generation (solar, wind), and battery energy storage systems (BESS)
- Develop, adapt, validate and troubleshoot detailed EMT models, including converter controls, plant controllers, protection systems and network equivalents.
- Assess converter performance under weak-grid conditions, faults, switching events, energisation, recovery following disturbances, and adverse control interactions.
- Validate EMT models against manufacturer documentation, test reports or engineering expectations to ensure technically credible simulation results.
- Investigate numerical convergence issues, control interactions, oscillations and unexpected EMT simulation behaviour, identify root causes, and develop technically justified solutions.
- Integrate, adapt and validate manufacturer-supplied EMT models while ensuring consistency with study objectives and network representation.
Grid integration converter-based resources
- Contribute to grid integration studies involving inverter-based resources (IBR) and HVDC technologies
- Assess system impacts of converter-based resources and support identification of technical risks and mitigation measures
Project delivery s coordination
- Deliver defined EMT study tasks independently while working under the technical guidance of senior engineers on more complex assignments.
- Coordinate with internal teams for inputs, modelling assumptions, and validation
- Support RMS and steady-state teams to ensure consistency between EMT and system-level studies
Reporting technical interaction
- Prepare high-quality technical reports, clearly communicating modelling assumptions, study methodology, key findings and engineering recommendations.
- Present results and conclusions to internal teams and support client discussions when required
Continuous development
- Contribute to the development of internal EMT modelling practices, reusable libraries, automation tools and technical guidance documents.
- Stay updated on developments in HVDC, inverter-based technologies, and EMT simulation tools
- Develop expertise in advanced EMT applications, including HVDC, grid-forming inverters, renewable plant controllers and interactions between inverter-based resources.
