The Senior Grid System Design Engineer is the technical "Gatekeeper" for our BESS pipeline. This role carries dual responsibility: performing the advanced mathematical simulations required for TNB approval and acting as the primary technical auditor for BESS and PPC hardware suppliers. Key ResponsibilitiesBESS Dynamic Modeling: Develop site-specific BESS models including Inverters (PCS), Battery Management Systems (BMS), and Power Plant Controllers (PPC). You must accurately model GridForming (GFM) logic, Virtual Inertia, and sub-50ms Fast Frequency Response (FFR).Supplier Technical Auditing: Critically review BESS and PPC supplier proposals. You must verify if their stated ramp rates, Round Trip Efficiency (RTE), and control loop latencies are mathematically achievable and compliant with TNB requirements.Grid Impact Studies: Lead the execution of Load Flow, Short Circuit, and Transient Stability studies. must specifically address Weak Grid ($SCR < 2.0$) challenges and ensure the BESS does not cause sub-synchronous oscillations. TNB Regulatory Representative: Serve as the lead technical representative at TNB GSO (EMS Unit) meetings. You will defend the simulation results and manage the end-to-end Interconnection Agreement (IA) process.Harmonic & Power Quality Validation: Perform detailed harmonic resonance studies to identify if a supplier's inverter switching frequency will clash with the local TNB grid impedance.RequirementsBachelor’s or Master’s Degree in Electrical Engineering (Power Systems or Power Electronics focus).Experience: * Minimum 8+ years in utility-scale power systems.Direct experience in modeling at least two utility-scale BESS projects (min 10MWh+) in a professional simulation environment.A proven track record of at least 3 successful TNB Grid Impact Study (GIS) approvals.Professional Status: Must be a Professional Engineer (Ir.) or a high-level Graduate Engineer registered with the Board of Engineers Malaysia (BEM).Technical Authority: Ability to demonstrate prior experience in rejecting or correcting supplier technical designs based on simulation findings.
