Abstract
The demand for electrical energy has continued to increase in recent years, as well as the constraints linked to its production, such as the effect of pollution and global warming, are driving research towards the development of renewable energy sources. In this context, photovoltaic (PV) systems offer a very competitive solution. To overcome the efficiency problem of solar panels and achieve maximum efficiency, it is necessary to optimize the design of all parts of the PV system. In addition, it is necessary to optimize the Static converters employed as the interface between the PV generator and the load in order to extract the maximum power and thus operate the GPV generator at its maximum power point (MPP) using an MPPT controller (maximum power point tracking), consequently, obtain a maximum electric current under the variation of the load and the atmospheric conditions (brightness and temperature). In this work, we briefly describe the most used solar cells and their operating principles, as well as the modeling of a photovoltaic cell (CPV), the influence of different metrological parameters (temperature and illumination). and we review the types of static converters DC / AC converters and DC / DC converters (buck, boost and buck boost), then we Study of different MPPT methods, and it is which searches for the maximum power point when the GPV is coupled to a load through a static converter after that, a simplified model of PV system is implement, and it is tested to work. Then, different methods are implemented. after all methods operate correctly, main features are analyzed and compared to other methods, and all results and conclusions are obtained.
