Optimized Design for Proportional Resonant Control Strategy for Power Quality Improvement in Grid Connected Three Phase Power Converters

A. U. Essien & F. U. Ilo · Journal of Energy Research and Reviews · 2026

This work focuses on the modelling and simulation of a Proportional Resonant (PR) current controller designed to mitigate, to an acceptable limit, the current harmonics that distort the output current of the Voltage Source Inverter (VSI) tied to the utility grid. To achieve this,...

Modelling, Design and Performance Analysis of LCL Filter for Grid Connected Three Phase Power Converters

A. U. Essien & F. U. Ilo · Journal of Energy Research and Reviews · 2022

The use of Power Converters to integrate renewable sources of power with the ac grid has been on the increase in the last two decades. An LCL filter is often used to interconnect the Power Converters to the utility grid in order to filter the high order harmonics produced by the...
