Modeling and simulation of the control of a photovoltaic inverter for a solar microsystem according to energy quality criteria

Abstract

In this work, an analysis of the quality of electrical energy in photovoltaic solar microsystems isolated from the grid is carried out. In these systems, the fundamental element is the bridge-type controller inverter. The control of the trip of the switches is carried out by means of pulse width modulation (PWM). The use of Simulink / Matlab applications and models allows simulating different control strategies in these systems and proposing control solutions that contribute to improving the quality indicators of the technical product. In this work the simulation of a single-phase system isolated from the grid and with residential load is carried out. The control scheme is designed using a Proportional - Resonant controller for the reduction of the total harmonic distortion (THD) in the voltage at the output of the filter of the photovoltaic solar inverter.

Resumen

En este trabajo se realiza un análisis de la calidad de la energía eléctrica en microsistemas solares fotovoltaicos aislados de la red. En estos sistemas, el elemento fundamental es el inversor controlado tipo puente. El control del disparo de lo interruptores se realiza mediante pulse width modulation (PWM). El empleo de aplicaciones y modelos del Simulink / Matlab permiten simular distintas estrategias de control en estos sistemas y proponer soluciones de control que contribuyan a mejorar los indizcadores de calidad del producto técnico. En este trabajo se realiza la simulación de un sistema monofásico asilado de la red y con carga residencial . Se diseña el esquema de control emxpleando un contrlador Proporcional – Resonante para la reducción de la distosión armónica total (THD) en la tensión a la salida del filtro del inversor solar fotovoltaico.
