Project Scope:
Assessment of harmonic interactions between power converters and transmission networks, focusing on stable system operation and power quality in the presence of power electronic devices.

Key Responsibilities & Achievements:

• Analyzed harmonic performance of HVDC converters and their impact on grid stability.

• Developed Python tools to create impedance envelopes (R-X) for harmonic scans, considering network contingencies (n-1, n-2).

• Applied tools to real projects to determine harmonic current thresholds for converter specifications (e.g., STATCOM and HVDC projects), based on international standards (TR IEC 61000-3-6).

• Reviewed methodologies and international best practices for conducting power quality studies.

• Evaluated modeling requirements for harmonic analyses across relevant frequency ranges and phenomena.

Outcome:
Delivered validated harmonic analysis tools and methodologies, enabling robust specification of power electronic devices and enhanced system security against harmonic-induced instabilities.
