Abstract

The control in an inverter system for photovoltaic applications is important as it can impact on the efficiency of the system. In this paper a review of the main control strategies used in photovoltaic systems is presented. The study is divided into two branches: grid connected systems and off-grid systems. The paper includes a review of strategies common to both types of systems, including a comparison of both linear and non-linear control strategies. In addition, the implementation of an MPPT algorithm which gives an increase in the efficiency of the generation systems is described. Although there is a large variety of control strategies, there are some that offer better results, from both point of view the computational consumption and the system efficiency, these differences are identified in the presented results.
