| | Résumé : | This work aims to study and improve the performance of standalone PV systems. In the beginning, we modeled the system composed of the photovoltaic generator and the Boost converter. Then, the model was used in the design of the PID controller. The latter was designed to improve the response time of the system, which, later on, helped to track the maximum power of the PV generator in a short time, and therefore increasing the power yield. After, we investigated different methods of tracking the maximum power point of the PV generator, which was improved and tested under uniform constant and variable solar radiation, and then under partial shading effect where several local maxima and one global maximum can be appeared. The system was then extended to consist of two networks, DC and AC, as well as a battery storage unit. The stability of the system was related to the stability of the DC voltage. For this reason, a Sliding Mode controller was designed to control the DC bus voltage, which gave very satisfactory results. The system was tested using Matlab/Simulink software,then experimental tests were carried out. | | note de thèses : | Thèse de doctorat en génie électrique |
