Diseño y simulación de la operación y control de los convertidores estáticos de energía en una micro-red eléctrica inteligente (Micro-Smart Grid) aplicado un sistema de alumbrado público a partir de fuentes de energía renovables (fotovoltaica y eólica).

Abstract

This project consisted in to design and simulates the operation and control of static power converters in a Micro Smart Grid, applied to a system of street lighting, with energy sources solar photovoltaic and wind. The main purpose was to study of feasibility to apply hybrids projects of renewable energies (wind and PV). In these systems, the parameters of voltage and current were monitored all the time, as same as a MPPT (Maximum Point Power Tracker) strategy was implemented. In the case of PV, an algorithm with the technical "incremental conductance" was implemented, and in the case of wind generator, the technical of perturbation and observation. Both provides the duty cycle for the power semiconductors. Buck-Boost converter was used in these two systems to provide the required current for the load and for the battery. The storage energy system works as a bi-directional DC / DC converter and performs the control for the load and for the battery. LED Lamp works by means of a DC/DC reducer converter in order to maintain a constant current. Finally, as conclusion, the applied control strategies in each system, shown that the proposed system is environment friendly, efficient, reliably and robust.
