Compensation Strategies for Shunt Active Power Filter in Single- and Three-Phase Systems: Different Formulation, Comparison and Evaluation

Indirect Control of Single-Phase Active Power Filters using Harmonic Control Arrays

The ever increase of nonlinear loads in electric distribution networks causes many problems due to the high level of harmonic currents. This paper proposes a new technique for controlling a single phase shunt active power filter based on a selective compensation using the newly developed technique of harmonic control arrays. Simulation results confirm the appropriate selective harmonic compensa...

Harmonic Compensation Using On-Line Bacterial Foraging Optimization Based Three-Phase Active Power Filter

The active power filter has gained much more attention because of its effective performance to mitigate the harmonics. This paper presents shunt active power filter (SAPF) controlled by PI controller to compensate the harmonics. Also, it introduces a new artificial intelligent technique called Bacterial Foraging Optimization to optimize the parameters of the PI-controller through on-line self-a...

A Three-Phase Active Power Filter for Harmonic and Reactive; Power Compensation

In this paper, a 3-phase active power filter (APF) is presented to eliminate harmonics and to compensate the reactive power of an uncontrolled rectifier with capacitive loading taken as non-linear load. An APF is realized using 3-phase voltage source inverter (VSI) with dc bus capacitor. Reference source currents are estimated using P-I control over dc bus voltage and 3-phase source voltages. C...
