Abstract	To mitigate the instability of power systems caused by the increasing penetration of renewable energy sources, the installation of Static Synchronous Compensator(STATCOM), which serve as reactive power compensation devices, is on the rise. These devices, composed of converters with switching elements, generate harmonics, which can lead to harmonic interaction issues with nearby power electronics based equipment. Therefore, a detailed analysis of harmonic interaction is required when designing and operating STATCOM systems. In this paper, impedance modeling of the power system and STATCOM is implemented using Matlab software, and the possibility of resonance occurrence due to changes in controller parameters when integrating STATCOM into the power system is analyzed.
