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.
