Hybrid DC Micro-Grid System for Smart Energy Delivery

Abstract

This paper proposes a Novel   DC Micro-grid System for smart Energy distribution. The power send to the System from five different sources which from DC micro grid, The Sources are wind, solar, Battery, ac source, and ultra-capacitor all together, form DC micro grid for smart energy delivery. DC micro grid are use to provide output power to three different load namely single-phase output, 100V DC output and 48V DC output,. The grid is at 230Vrms with 50Hz connected to a isolator in connection with the DC bus. The MOSFET switch provide in the ZETA converter switches according to the duty ratio given by the Fuzzy controller for which the input is given from the error value of the reference and measured output DC value of the ZETA converter. It a closed loop control system with feedback fuzzy controller circuit and the switching frequency of the ZETA converter is 45kHz. The converted DC voltage form the ZETA converter is fed to the DC bus where all the other modules are connected. Overall system run using MATLAB 2016 A
