Abstract
This paper focuses on a four-wire shunt active power filter (APF) control scheme proposed to improve the performance of the APF. This filter is used to compensate harmonic distortion in three-phase four-wire systems. Several harmonic suppression techniques have been widely proposed and applied to minimize harmonic effects. The proposed control scheme can compensate harmonics and reactive power of the nonlinear loads simultaneously. This approach is compared to the conventional shunt APF reference compensation strategy. The developed algorithm is validated by simulation tests using MATLAB Simulink. The obtained results have demonstrated the effectiveness of the proposed scheme and confirmed the theoretical developments for balanced and unbalanced nonlinear loads.

It has been proved by many reported work that these nonlinear loads are the main cause of poor power factor and high harmonic distortion [2]
Summary
Power electronic equipments are largely used in modern electrical systems leading to an increase of the harmonics pollution in the AC main supplies. The presence of harmonics in the power system results in numerous drawbacks such as high power loss in distribution network, electromagnetic interference in communication systems, and failures of power protection devices and electrical and electronic equipments These drawbacks can greatly affect the industrial process and commercial activities because they can lead to a decrease in the productivity and can affect the quality of the products [3]. The APF was deeply studied and applied as an efficient solution to the problem of harmonics pollution and their effects [4] This type of filters is proved as an appropriate technique to suppress harmonic voltage and current disturbances [5, 6]. To validate and confirm the developed algorithms for the proposed scheme, simulation tests are conducted to show the effectiveness of this approach
