Passivity-Based Stability Design of LCL-Filtered Converters: An Overview
2023 IEEE Applied Power Electronics Conference and Exposition (APEC), 2023 The stability of LCL-type grid-connected converters in distributed power generation systems (DPGS) have been numerously investigated. It is well known that resonance of high-order filters may cause system oscillations and grid current distortion. This phenomenon is more critical when the DPGS contains capacitive loads and cables.
