Combining advanced technical work with project coordination responsibilities. 🔹 Technical focus: development of user-defined dynamic models, simulation of power systems with high penetration of power electronics, control strategies for grid stability, and inertia/oscillation analysis. 🔹 Project management: coordination of Siemens Energy’s contributions in multinational R&D projects, leading tasks and ensuring alignment with partners through regular progress reviews. This dual role allows me to contribute both as a technical expert and as a project coordinator, ensuring innovative results that strengthen grid reliability and support the energy transition.

Led the development of time-domain simulation models for General Electric’s Haliade-X wind turbine auxiliary systems, with a focus on harmonic performance and filter design. 🔹 Built detailed models to assess harmonic distortion and dynamic interactions within large wind turbine platforms. 🔹 Designed and evaluated passive harmonic filters, optimizing frequency response and system stability. 🔹 Supported system-level studies through parameter tuning, waveform analysis, and validation of model fidelity. 🔹 Additionally, contributed to eRoots’ internal R&D projects by developing user-defined dynamic models in DIgSILENT PowerFactory, PSCAD, and MATLAB/Simulink. This position strengthened my expertise in harmonic analysis, model development, and filter optimization for converter-dominated renewable energy systems.

Developed and optimized electrical simulation models for Nordex wind turbines using PSCAD, PowerFactory, MATLAB/Simulink, and PSS®E. 🔹 Conducted transient and steady-state studies, benchmark validations, and grid-code compliance analyses. 🔹 Contributed to model standardization and automated validation processes. 🔹 Collaborated with grid integration teams to ensure accurate dynamic behavior representation in power-system studies. This work provided valuable practical insight into modeling and validation of converter-based renewable energy systems.

Contributed to EU-funded projects (FLEXITRANSTORE and INTERFACE) focused on modeling and control of converter-based renewable power plants. 🔹 Developed user-defined dynamic models in DIgSILENT PowerFactory (DSL) and PSS®E (Fortran), representing PV, wind, and battery systems. 🔹 Designed and implemented control algorithms in MATLAB/Simulink, later integrated into PowerFactory, PSS®E, and PSCAD. 🔹 Automated static and dynamic studies — including load flow, RMS/EMT, and modal analysis — using Python and DPL. 🔹 Performed real-time simulations in OPAL-RT ePHASORsim, adapting models for HIL validation of control strategies. This role strengthened my expertise in both offline and real-time power-system modeling, bridging simulation, control design, and automation across multiple software platforms.

Carried out doctoral research focused on modeling, simulation, and control of hybrid AC/DC power systems with high renewable penetration. 🔹 Developed and validated dynamic models of converter-based power plants and hybrid grids. 🔹 Designed and tested virtual synchronous machine (VSM) and other grid-forming control strategies for VSC-based AC/DC links. 🔹 Performed detailed stability, modal, and transient analyses using DIgSILENT PowerFactory, PSS®E, MATLAB/Simulink, and PSCAD. 🔹 Contributed to scientific publications and collaborated with industry partners for applied validation. This research strengthened my expertise in advanced modeling and control of converter-dominated power systems, integrating theoretical development with practical application.
