Key Responsibilities

LSC JD summary: Grid-Side Converter Control Consultant with strong expertise in grid-forming (GFM) and grid-following (GFL) control strategies, MATLAB/Simulink-based model development, and real-time validation of converter controls for renewable-energy and power-electronics applications. This role focuses on the development, modelling, and validation of control algorithms for grid-connected converters, including weak-grid stability, synchronization, and grid-code-related performance. Grid-Side Converter Control Consultant with strong expertise in grid-forming (GFM) and grid-following (GFL) control strategies, MATLAB/Simulink-based model development, and real-time validation of converter controls for renewable-energy and power-electronics applications. This role focuses on the development, modelling, and validation of control algorithms for grid-connected converters, including weak-grid stability, synchronization, and grid-code-related performance. Key Responsibilities 1. Grid-Side Converter Control Development • Develop and refine grid-forming control strategies, including VSM-type control, droop control, and other voltage-forming algorithms. • Design grid-following control loops, covering active/reactive power control, current regulation, and sequence-component-based controllers. • Ensure converter stability and robustness under weak-grid conditions, grid disturbances, and low short-circuit-ratio operation. 2. Synchronization & PLL Development • Develop and validate advanced PLL architectures (e.g., SOGI-PLL, CDSC-PLL, adaptive PLLs) for disturbed or weak grids. • Evaluate synchronization performance across various grid conditions including dips, unbalance, harmonics, and dynamic frequency changes. 3. MATLAB/Simulink Modeling & Simulation • Build and maintain detailed converter, network, and controller models in MATLAB/Simulink and related toolchains. • Conduct small-signal stability analysis, impedance-based assessments, harmonic studies, and transient simulations. • Use MIL/SIL/HIL workflows to ensure accuracy from model to implementation and support system-level optimization. 4. Real-Time Validation & Hardware-in-the-Loop Testing Classification: Confidential • Validate control algorithms using real-time simulators such as Typhoon HIL, dSPACE, OPAL-RT, or RTDS. • Reproduce grid-disturbance scenarios including islanding, fault ride-through, harmonic distortions, frequency deviations, and resonance issues. • Verify robustness and compliance across a wide range of operating conditions. 5. Weak-Grid Engineering & Stability • Analyze converter–grid interactions, resonance behavior, and control-loop sensitivity under weak-grid conditions. • Develop mitigation strategies such as adaptive current control, virtual impedance, damping algorithms, and enhanced synchronization filters. • Support design decisions related to filter tuning, grid-compliance behavior, and multi-converter interoperability. 6. System Integration & Cross-Functional Support • Collaborate with electrical, software, and system-engineering teams on grid-converter interfaces. • Support commissioning activities, troubleshooting, parameter tuning, and compliance-driven testing. • Prepare high-quality documentation, simulation reports, stability assessments, and validation packages for internal and external stakeholders. Required Skills & Experience • Strong background in power electronics, grid-connected converters, and renewable-energy integration. • Expertise in grid-forming and grid-following control concepts, including dq0-based current control and voltage-forming control structures. • Proficiency in MATLAB/Simulink, model-based development, and converter-grid interaction modelling. • Experience using HIL/CHIL platfor
