Effect of Line Impedance on the Stability of Shunt Active Power Filter Based on LCL Filter [PDF]
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.

Shunt active filter for power quality improvement [PDF]
This paper describes the development of a low cost shunt active power filter with digital control, which allows dynamic power factor correction and both harmonics and zero-sequence current compensation. The active filter controller is based on the instantaneous power theory (p-q theory) and was implemented using a standard 16 bits microcontroller.
