Abstract
En los últimos años a crecido en gran medida el interés por los medios de generación renovable, puesto que permite aprovechar energía muy abundante, junto con la gran ventaja de ser reducida en su nivel de contaminación. Lamentablemente dichas fuentes de energía tienen la desventaja de ser muy variables, pudiéndose aprovechar por una fracción del día y en muchos casos de forma impredecible, es por esto que los medios de almacenamiento de energía se vuelven indispensables para su funcionamiento adecuado y económicamente viable. Dada la gran importancia de los medios de almacenamiento, este trabajo se centra en la correcta utilización de un acumulador, el cual tiene como objetivo almacenar energía durante el día, para entregarla en las horas de más utilización del sistema eléctrico, horas que consecuentemente es donde menos generación solar se tiene. Debido al relativo desconocimiento sobre las características fundamentales que tienen estos dispositivos, se parte analizando su diseño y funcionamiento, para así poder conocer cuales son los más adecuados al sistema bajo estudio. Para utilizar de forma adecuada una batería, se diseña un algoritmo que administra la energía que entra y sale de ella, definiendo para ello un proceso de carga y uno de descarga. En el primer proceso, se crea un sistema de carga que permita almacenar la energía a descargar, de forma eficiente y segura, evitando sobre cargas y violaciones a los límites técnicos del acumulador.
In the last few years, a big interest has developed for the means of renewable energy, because they allow to take advantage of an abundant source of energy, together with the added advantage of a reduced level of contamination. Sadly said energy sources have the disadvantage of great variability, only being able to take advantage of them for a fraction of the day, and in many cases in an unpredictable way, hence the means of energy storage have become essential for their adequate functionand economic viability. Given the great importance of said means of energy storage, this work will focus in the correct use of an accumulator, which has the objective of storing energy during the day, for later use during the electrical systems peak hours, which consequently are the hours of least solar energy output. Because of the relative ignorance about the fundamental characteristics of these devices, this work will start by analizing their design and functioning behavior in order to acknowledge which of said accumulators are best suited to the system under study. To make use of a battery in a proper way, a battery management algorithm is designed, defining for that purpose a process of charge and discharge. In the first one, a system of energy charging is created, to make use of the accumulator in an efficient and secure way, avoiding overcharges and violations of the technical limits of said device.
