A Review on Enhancing Smart Grid Power Quality

Abstract

A microgrid can supply electricity to isolated or localized locations by combining dispersed generation with local loads. The integration of microgrids with Egypt's electrical infrastructure is one of the latest advances. Smart microgrids and utility systems can be integrated to handle power quality problems like deep energy, power loss, voltage drops, and increasing distributed generation utilization. This study looks into a few common and significant power quality issues related to the integration of smart microgrids and utility systems, like voltage fluctuation and total harmonic distortion (THD) at different solar irradiance and load scenarios. The integration of smart microgrids and utility systems, as well as the problem with power quality at different loads, were modeled and evaluated using MATLAB and Simulink code specifically created for this project. This study looks at two THD scenarios and five voltage analysis scenarios at different irradiance levels. The results show that while the voltage drop percentage increases at all load levels with low solar irradiance, it decreases with high solar irradiance. Furthermore, THD decreases with increasing sun irradiation at both high and low loads, and the opposite is also true.
