Effect of Line Impedance on the Stability of Shunt Active Power Filter Based on LCL Filter

Kongzhi Yu Xinxi Jishu, 2018
When shunt active power filter based on LCL filter is used for voltage source type harmonic source, the line and load impedances will not only cause the harmonic amplification but also the stability problem based on current tracking.

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
