Adaptive Controller for Bus Voltage Regulation on a DC Microgrid Using a Sepic/Zeta Battery Charger/Discharger

In a DC microgrid that involves battery storage system, the primary energy management is performed by charger/discharger based on dc/dc power converter. Moreover, also used to regulate voltage of dc bus. One challenges at control level bus under charge and discharge conditions but different relations between voltages. For this reason, paper proposes Sepic/Zeta converter an adaptive controller, which provides bidirectional current flow, stable voltage, satisfactory electrical characteristics. The main advantage proposed system capability adapt controller parameters any operation condition, general solution interface voltage. This study focused design procedure both where detailed mathematical analysis ensure performance stability. Finally, validated using experimental prototype practical application case.
