Estudio de la probalidad de pérdida de carga y pérdida de carga horaria para sistemas fotovoltaicos autónomos y/o conectados a la red en Ecuador

Abstract

In this thesis the analysis and evaluation of different methods of sizing of a photovoltaic solar system mainly based on reliability by generating isoreliability lines, and then make a comparison between them and the classical methods are performed. Furthermore, methods are presented to generate radiation data schedules and diaries. The results of these methods are compared with real data and the results of the sizing methods using each of these data are evaluated.

The first chapter, discusses the state of art of photovoltaics energy situation, both in the world and in Ecuador, in addition to some definitions of reliability, and a brief description of the used methods. The second chapter, refers to the theoretical framework and the importance of studying the reliability of photovoltaic solar systems, the description of the types of solar photovoltaic systems, its operation and its elements. In the third chapter, some procedures for radiation data generation are exposed, which are used in the methods of sizing photovoltaic systems, then, the procedure for sizing the stand alone and grid connected PV – systems will be displayed. In the fourth chapter, the results of applying each of the sizing methods are exposed, an analysis and comparison of the results are also performed, using real data and data generated. In the fifth and final chapter, the conclusions and recommendations are presented.
