摘要

Population growth increased the need for energy, which led us to use new and clean energy sources. The microgrid is considered one of the best solutions for energy supply, which is one of the main challenges. Here, voltage profile problems in microgrids cause instability in microgrids; PI and phase-proportional-integral controllers stabilize the microgrid's voltage to eliminate the disturbance. Still, the problems with this method are the number of Energy Storage system charges and discharges, which reduces the life of batteries and increases the cost of the system. This article tries to use the optimized FUZZY-PI to control the microgrid voltage by presenting a new solution, which improved the voltage profile with an error of less than one percent. In addition to enhancing the voltage, the proposed method led to stabilizing the microgrid. The practical aspect of this study is the minimum amount of charging and discharging of the battery, leading to increased battery life.
