Optimalisasi Kinerja Hibrida Baterai Dengan Super Kapasitor untuk Sistem Mikrogrid

Abstract

A microgrid is a small network consisting of several renewable energy sources such as wind, solar, geothermal, bioenergy, water and so on. However, the disadvantage of this system is that the power fluctuates and when the source does not produce power at a certain time. So power storage media such as batteries and supercapacitors are needed to maintain continuity when the source does not supply enough load. This research uses data taken at the Nomensen campus, with a hybrid storage medium in the form of 1 battery unit and 1 super capacitor unit with an energy storage system to get optimal performance, and will be simulated with Simulink Matlab. The purpose of this study is to obtain the effect of adding a super capacitor with a battery and comparing it with no super capacitor. From the results of the study, it was found that the addition of super capacitors can maintain stable charging of the battery from 49.5% State of Charge (SOC) to 49.67%, while the battery storage medium without super capacitors, battery charging tends to decrease from 49.5% to 49.3% and continues to decrease without any increase at all.
