Influence of environmental changes on power quality disturbances in Hybrid Renewable Energy System

Abstract

Environmental changes profoundly affect PQ disturbances in Hybrid Renewal Energy Systems (HRES). The stand-alone hybrid renewable energy system is increasing its share of the energy sector. This process is now opening doors for research into this area. The power produced by these sources, especially solar and wind systems, depends on environmental conditions. Consequently, these systems behave differently under varying conditions. The research will focus on how these environmental changes can influence disturbances to power quality in the systems. The main focus will be on total harmonic distortion and other related power quality issues, including voltage sag, swell, and changes in current values. The research will be conducted by using MATLAB simulation of the system. The simulation will be tested utilising different environmental conditions, and data will be collected for analysis. The research would reveal which environmental factors will guide the hybrid system more than the other factors. To what extent do these environmental changes influence the PQ disturbances? The major contributing factor was irradiance level in the case of solar power and wind speed concerning wind power. The research will help to improve power supply in a stand-alone HRES.
