Abstract :
The Multi-infeed Interaction Factor (MIIF) is an important index for quantifying the interaction between the converters of a Multi-infeed (MI) HVDC transmission system. Using an analytical formulation of power flow, the impact of ac and dc side system parameters on the MIIF is analyzed. The analysis is conducted using a two-infeed HVDC test system derived from the CIGRE HVDC Benchmark model. Results show that the ac grid effective short ratios at the MI converters, length of the tie line connecting the converter ac buses, and the power flow distribution in the ac network are the main factors affecting the MIIF value. The magnitude of the voltage drop at the converter bus does not influence the MIIF value.
