Senior Grid System Design Engineer

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 Responsibilities

• BESS 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 clas
