Diseño e implementación de un seguidor del punto de máxima potencia mediante conductancia incremental.

Abstract

The project consists in the design and construction of a maximun power point tracker for photovoltaic modules, implementing the incremental conductance technique, due to its high efficiency and low complexity in the development of the algorithm, but which, under varying atmospheric conditions, allows the operation of the photovoltaic modules at their maximum power point. The modification of the electrical conditions of the photovoltaic system is done by means of a DC / DC type Cúk converter, which requires a set of sensors and control circuit, designed to obtain the voltage and current values of the generator; then calculate incremental conductance magnitudes at defined time intervals and evaluate pre-established conditions (typical of the technique) that allow obtaining the point of maximum power.
