This work proposes the modeling of High Voltage Direct Current Link (HVDC) for harmonic analysis in AC electrical power systems using frequency domain formulation with complete and explicit representation of the AC and DC networks, as well as, the converters non-linear characteristics and their harmonic interdependences. The proposed model development is based on the Three-phase Harmonic Current Injection Method (THCIM) and it allows the systemic simulation of AC networks with DC link of high complexity, as 12-pulse converter systems and asynchronous AC connection. The proposed model simulation results, in frequency domain, were validated against ATP (Alternative Transients Program) results, in time domain simulation.
