A novel robust active damping control strategy based on H∞ loop shaping for the grid-tied LCL inverter

Frontiers in Energy Research
LCL-type grid-connected inverters have been widely used in renewable power generation due to their size and cost advantages. However, the LCL filter has a problem of insufficient damping, which may lead to power system instability. Two common methods are

Passivity-Based Stability Design of LCL-Filtered Converters:An Overview

, 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.
