Re-boost Converter enabled DC Microgrid System with Sliding Mode Control and Maximum Power Point Tracking

Abstract

In this work, a novel control strategy is proposed to provide a ‘‘rapid acting Maximum Power Point Tracking (MPPT) Technique for solar photovoltaic system amid rapidly fluctuating solar radiation’’ with energy management for DC Microgrid. This system comprises of the solar, wind power sources and a battery backup. Re-boost converter is used to transform the energy produced. The DC link component of the conventional system is replaced by a re-boost converter. A boost converter is a DC-DC converter that raises or enhances output voltage. The suggested converter’s efficiency is principally attained while switching stress is kept to a minimum since it has a power MOSFET switch. The Re-boost converter provides a consistent input current while reducing voltage stress. Both the output ripple voltage and total harmonic distortion factor are kept to a minimum. The DC Microgrid receives the converted energy to meet demand. The system has been set up with a closed loop to ensure efficient operation. The controller is a component of the closed loop setup. One traditional controller, the PI controller, and one innovative controller, the Sliding Mode controller, are both used in this study. The most efficient controller for the suggested system will be found after the results of the controllers were compared.
