Optimizing Microgrid Efficiency with Battery and Super Capacitor Hybrid Systems

Abstract

Microgrids are small networks consisting of several renewable energy sources such as wind light, sunlight, geothermal, bioenergy, water and so on. But the drawback of this system is in fluctuating power and when the source does not produce power at a certain time. So that power storage media such as batteries and supercapacitors are needed to maintain contingency when the source does not supply enough load. The purpose of this study was toobtain the effect of adding supercapacitors with batteries and compare battery storage media without supercapacitors. From the results of the study, it was found that the addition of supercapacitors can maintain battery stability charging from 50% State of Charge (SOC) down to 47% and start It rises back by 50% at 1 second, as well as additional charging can be set to our liking. If the battery storage media is without supercapacitors, battery charging tends to drop from 50% and continue to fall without any increaseat all. So it can be concluded that with the addition of supercapacitors are able to maintain the performance of the battery in the microgrid system.
