Impact of Load on Total Harmonic Distortion in a Photovoltaic System

Abstract

Environmental concerns are the biggest reasons for the rising interest in Renewable Energy sources. Rapid industrialization and urbanization have forced engineers to look at cost-effective sources. Power quality issues are increasing day by day. The introduction of sensitive equipment into an electrical grid is an essential factor for the introduction of these problems in the grid. The introduction of Renewable Energy (RE) sources into the system can increase PQ disturbances in the system. The addition of sensitive equipment in the electrical system can cause compatibility issues. The compatibility issues take centre stage if RE sources are part of the electrical system. These compatibility problems become complex if multiple sources are used to produce power. The type and size of the load in the electrical system play a vital role in the introduction of PQ disturbances. These PQ disturbances can bring changes in voltage or current value. The impact of the load should be studied in detail to understand its impact on the system. This paper presents the results of a study based on the impact of load on a PV system. The impact of different types of loads on the electrical system was investigated, and results were collected to facilitate future research. Total harmonic distortion (THD) was given more importance.
