Mitigation of power quality issues in smart grids using shunt active power filter

Over the past two decades, there has been a significant shift in energy demand due to the widespread use of electronic devices with semiconductor components. The term ‘smart grid’ refers to an electricity delivery process that optimizes energy efficiency by connecting central and distributed generators to industrial and consumer end-users, integrating power distribution with consumer communication for secure and reliable power transfer with digital control, essential in modern power systems due to growing customer interest in digital control across various fields, including power supply. The paper simulates a smart grid design model in MATLAB/Simulink, incorporating power supply from the grid, solar array, battery, and fuel cell, to identify power quality issues under linear and non-linear loading. It proposes a controlling scheme to mitigate power quality issues, focusing on harmonic monitoring, measurement, and reduction techniques.
