Master Thesis: Evaluation of Simulation Models for Flicker and Harmonics

ices for grid studies.

How you'll make an impact:

• Model power system components including electrical arc furnaces and STATCOMs using DIgSILENT PowerFactory in both RMS and EMT simulation modes.

• Conduct time-domain simulations to analyze flicker and harmonic behavior under various grid conditions and control strategies.

• Compare simulation results from PowerFactory models against Hitachi Energy's internal PSCAD model to assess fidelity and performance.

• Evaluate control algorithm impact by quantifying differences in flicker damping between simplified and detailed STATCOM models.

• Develop recommendations for using publicly available simulation tools to assess flicker performance in compliance with grid codes.

• Document findings and methodologies, with the potential to contribute to a technical paper summarizing the study and its implications.

• Living Hitachi Energy's core values of safety and integrity means taking responsibility for your own actions while caring for your colleagues and the business.

Your background:

• Master's student in Electrical Engineering, Power Systems, or related field.

• Strong interest in power quality, grid simulation, and control systems.

• Familiarity with simulation tools (PowerFactory, PSCAD) is a plus

• Analytical mindset and ability to interpret complex system behavior.

• You possess strong motivation, problem-solving skills, and the ability to complete tasks.

• Proficiency in English language, both written and spoken.
