Resumen


Resumen

Los convertidores CD/CA se utilizan ampliamente en sistemas de generación fotovoltaica conectados a la red. Normalmente se utilizan sólo para inyectar potencia activa a la red, sin embargo, es posible integrar la función del filtro activo de potencia al mismo sistema, y entonces es posible eliminar los armónicos de corriente generados por cargas no lineales. El convertidor CD/CA tendrá esta capacidad de eliminar las corrientes armónicas mientras también inyecta potencia activa en la red, debido a la energía generada por los paneles solares. Este documento presenta una estrategia de control basada en una función de Lyapunov para un convertidor CD/CA monofásico para sistemas fotovoltaicas que considera la compensación armónica. Se presenta el análisis, diseño y los resultados de simulación.

Palabras Clave: Control por función Lyapunov, Filtro Activo de Potencia, Fotovoltaico, Fuente Renovable.

 

Abstract

The DC/AC Converters are being widely used in grid-connected photovoltaic generation systems. Usually they are used only to inject active power to the grid, however, it is possible to integrate the function of the active power filter to the same system, and then to eliminate the current harmonics generated by non-linear loads. So that the DC/AC converter will have the capacity to eliminate the harmonic currents generated by the nonlinear load while it is able to inject active power into the grid generated by the photovoltaic systems. This paper presents a control strategy based on Lyapunov-function for a single-phase DC/AC converter for photovoltaic systems that considers the harmonic compensation. The analysis, design, and simulations results are presented.

Keywords: Active Power Filter, Lyapunov-Function Control, Photovoltaic, Renewable Source.
