Power Quality Improvement using Shunt Active Power Filter: An Industrial Zone Case Study

Abstract

Power quality (PQ) improvement using active power filters (APF) is a topic of growing interest. APFs are effective in reducing harmonic distortion and improving power factor. They can be used in a variety of applications to improve the performance and reliability of electrical equipment. To address concerns with PQ improvement, this study offers an application of shunt APF in an industrial zone smart grid. the non-linear loads and unpredictable harmonics produced by on-grid PV inverters that represent the architecture of an industrial smart grid. Utilizing the MATLAB/SIMULINK software suite, a detailed design of the APF and associated hysteresis current control technique is provided. The findings demonstrate that APF is a useful tool for reducing total harmonic distortion (THD) and has a quick dynamic reaction to control grid voltage and power factor.
