Enhanced Power Management and Control of a PVWind- BES Based Microgrid System

Abstract

In this work, the design, control, and power management scheme of a solar, wind and battery energy storage (BES) based microgrid (MG) system is presented. The major power source in the proposed system is the PV, while the secondary power source is the wind. and battery energy storage system provide the backup power supply. The system can operate in “ off-grid” and“on-grid” modes, based on the power management control setup. The grid synchronization of the system is achieved by employing the power balance (PB) theory based control algorithm. This microgrid system is managed and controlled by an improved power management (IPM) algorithm to enhance the power quality, stability, and efficiency. The effectiveness of the suggested system is evaluated under numerous condition of uncertainties of weather conditions and instability of the utility grid power distribution system.
