INVESTIGATION ON A STANDALONE DC MICROGRID

Abstract

The Micro-Grid can be utilized for various purposes and specific requirements, including improving the local reliability and power quality, reducing feeder loss, supporting local voltages, supplying more efficiently using waste heat, and providing a voltage sag correction or supply UPS function, to mention a few examples. The Microgrid is also utilized to enhance the percentage of green energy penetration in order to reduce carbon dioxide emissions. The DC microgrids are an essential option, have gotten more attraction and significant attention in the recent years and nowadays accordingly several distinct merits such as less inverter price, straightforward analysis and design controlled, Also, in a DC microgrid various (DER), and simple control with absent reactive power issues. All these features of DCMG,s performance and investigated by using the various source to achieve the stability and improvement of the standalone DCMG grid as well and by using MATLAB Simulink to verify that.
