An efficient energy management system for a photovoltaic-wind and hybrid energy storage (HES) integrated multi source converter configuration for DC micro grid is proposed in this paper. The Renewable energy sources like photovoltaic-wind energy conversions systems are developed and used for integrating the multi-source converter with hybrid storage converter. The use of Super capacitor-Battery based HES are interfaced to handle the power fluctuations and sudden load disturbances. The super capacitors contain high frequency fluctuations and rapid charging of battery storage and increases the life time of battery storage and reduces the sizing of storage unit. The maximum power point energy storage is based on charging and discharging of power availability. The main aspects of proposed configuration are: (i). less number of switches, (ii). voltage boosting, voltage regulation of super capacitor and power sharing among battery are of same characteristics, (iii). simple control structure with a reduced number of sensors are used. This study will a new multi-source and hybrid energy storage combined converter for micro grid applications. The designing of the proposed configuration and control structure are simulated through MATLAB simulations and experimental validations.
