Abstract : In recent times, the focus of researchers has moved toward power quality domain due to its increasing importance in the profit and loss calculation of the industrial sector. The main industries like textile, glass, plastic and semiconductors are facing around 10 k\$ to 1 M\$ loss due to voltage sag. So, the focus is to improve the power quality. Various control algorithms such as IRPT and SRF are suggested for mitigating voltage-related issues. Usually, IRPT-based control algorithms are not commonly used for mitigating voltage-related issues as compensating voltage is not independent of load current. The researchers have attempted to modify the existing control algorithms to compensate voltage-related issues. In this proposed work, a modified version of IRPT controller is proposed to carry out voltage sag and swell compensation. The IRPT-based controller is simulated, and its performance is analyzed.
