R&D Modelling and Simulation Engineer (Edge Solutions, BESS) - IDC

Overview

Act as the system-level modelling and simulation Subject Matter Expert for GPQSS Battery Energy Storage Systems, delivering validated reference models and solution packages for tendering, execution and local engineering teams.

What you'll do

• Act as the system-level modelling and simulation Subject Matter Expert for GPQSS Battery Energy Storage Systems.
• Provide independent technical judgment on model selection, fidelity, assumptions, and applicability to BESS solutions.
• Ensure modelling approaches correctly represent overall system behaviour, performance, and limitations from an application perspective.
• Serve as technical reference and escalation point for modelling related topics across GPQSS.
• Integrate OEM provided models (PCS, battery, control systems) into standardized GPQSS system level templates.
• Develop, maintain, and validate reference BESS models and solution packages for RMS and EMT simulations.
• Execute solution validation studies to assess BESS performance, robustness, and compliance from an application and grid interaction perspective.
• Complement OEM models with in-house modelling where required to close gaps or increase simulation fidelity.
• Deliver validated modelling packages intended as kick starters for tendering and project execution.
• Provide methodology, validated models, and expert support to teams performing project-specific grid and system studies.
• Technically steer and enable external consultants, Power Consultants, and project engineers to effectively use GPQSS modelling packages.
• Support tendering and feasibility phases through interpretation of simulation results and clarification of modelling assumptions.
• Support grid code compliance assessments by providing reference models and validation frameworks, not by executing full project studies.
• Prepare and deliver training, documentation, and guidance on BESS modelling approaches, tools, and best practices.
• Capture and disseminate lessons learned to continuously improve modelling templates and solution packages.
• Contribute to cross-disciplinary alignment with System Architect, AC BoS, Battery Technology, and Automation roles.

What you'll need

• Master's degree in Electrical Engineering, Power Systems, or equivalent.
• Minimum 5 years of experience in power system modelling and simulation.
• Excellent knowledge of EMT and RMS simulation tools, with mandatory proficiency in PSCAD and DIgSILENT PowerFactory.
• Proven experience integrating OEM models into system-level simulation environments.
• Proven ability to develop reusable modelling assets and support multiple stakeholders, beyond single project execution.
• Solid understanding of power system dynamics, inverter-based resources, and BESS grid integration.
• Ability to independently drive end-to-end modelling and simulation activities.
• Strong collaboration skills in multidisciplinary and international teams.
• Excellent communication skills in English.

Nice to have

• Experience with PSS®E for large-scale transmission or regional power system studies.
• Experience with simulation automation or scripting (Python, MATLAB).
• Exposure to grid impact studies and grid-code validation processes.
• Experience working with external consultants, utilities, or TSOs.
• Structured, analytical, and pragmatic engineering mindset.
