A Novel Approach to Power Quality Improvement in Distribution Systems Using Fuzzy Logic Controller and PWM-Based Shunt Active Power Filter with Harmonics Reduction

Abstract

The proposed study emphasizes that a Shunt Active Power Filter (SAPF) is considered the most effective solution for addressing current harmonics. The research focuses on developing a shunt active power filter by incorporating a fuzzy logic-based controller as a key component. This construction aims to enhance the performance and effectiveness of the shunt active power filter in mitigating current harmonics. To evaluate the performance of the suggested model in an imbalanced load scenario, the proposed shunt active power filter has been compared to a typical shunt active power filter. The method is still believed to include extraneous characteristics that strain the controller's computing resources. In the power system, active control filters are frequently employed to decrease harmonics brought on by nonlinear loads. The greatest method for reducing harmonic issues in power systems is the shunt active power filter (SAPF), although its efficiency and speed are limited. Its algorithms are precise to control. In this article, a voltage source is controlled for current using a pulse-width modulation (PWM) parabolic carrier-based (PWM) technique. When using fuzzy based control technology, a single-stage system is used in conjunction with perturbation in certain situations. To model and simulate the system, MATLAB/Simulink is recommended.
