Low Cost Hybrid Energiess Smart Management System Applied for Micro-grids

This work aims to provide an intelligent low cost router system for hybrid system composed with solar, wind and batteries energy sources. The system is assisted by the electric-grid, in which according to the priority order fixed in the energy sources, provides the management of the power. This system is governed by a microcontroller with event display operations, allowing a non-interrupted feeding. It can be used especially in city or isolated sites. A parametric study of the system and simulation have been developed to highlight the proposed control strategy, the sizing of the hybrid system assisted by the electric-grid, applied to a dwelling electric charge consumption up to 3000 W/day. The current work is crowned by the realization of the intelligent router system connected upstream of a single-phase DC/AC inverter to power the alternative current load for accommodation.
