Diseño y simulación de la optimización en la generación de energía en una central fotovoltaica mediante conversores DC/DC y la técnica de control MPPT

Abstract

Solar radiation variation and temperature changes are the main causes that affect the operation of photovoltaic systems, presenting losses in the amount of electrical energy. Thus, there are MPPT control techniques and types of connections of the equipment that make up the photovoltaic system, which help the system to counteract certain variations. The aim of this work focuses mainly on conducting a study to look for an increase in the amount of active power generated by the Salinas de Ibarra photovoltaic power plant. To address this problem, we propose the insertion of DC / DC converters in the arrays of solar panels, using MPPT algorithms and the power semiconductors being switched through a cascade control scheme that consists of an internal loop of current using an SMC controller, while an external loop that is responsible for controlling the voltage generated by the solar panels through a controller type PI. For the validation of the operation of the system, the amount of energy generated by the equivalent model without converters and the equivalent model is compared with the insertion of DC / DC converters.
