Engineer

• Develop and refine grid-forming control strategies, including VSM-type control, droop control, and voltage-forming algorithms.
• Design grid-following control loops for active/reactive power control, current regulation, and sequence-component-based controllers.
• Ensure converter stability and robustness under weak-grid conditions, disturbances, and low short-circuit-ratio operation.
• Develop and validate advanced PLL architectures for disturbed or weak grids.
• Build and maintain converter, network, and controller models in MATLAB/Simulink.
• Conduct small-signal stability analysis, impedance-based assessments, harmonic studies, and transient simulations.
• Use MIL/SIL/HIL workflows for model-to-implementation accuracy and system-level optimization.
• Validate control algorithms using Typhoon HIL, dSPACE, OPAL-RT, or RTDS.
• Reproduce grid-disturbance scenarios, including islanding, fault ride-through, harmonic distortions, frequency deviations, and resonance issues.
• Analyze converter-grid interactions, resonance behavior, and control-loop sensitivity under weak-grid conditions.
• Develop mitigation strategies including adaptive current control, virtual impedance, damping algorithms, and enhanced synchronization filters.
• Collaborate with electrical, software, and system-engineering teams on grid-converter interfaces.
• Support commissioning, troubleshooting, parameter tuning, and compliance-driven testing.
• Prepare documentation, simulation reports, stability assessments, and validation packages for stakeholders.
