Abstract: Nowadays, PV plants have two main drawbacks, the high cost of cells production and their low energy conversion efficiency. Commercial modules are assembled with efficiency between 6 and 16% depending on their technology. Due to this poor efficiency, strongly dependent on solar radiation level and operating temperature, it is very important to achieve its maximum value. There are two main techniques to get good results. One is the use of electro-mechanical equipment. These equipments allow PV modules keep the best position to obtain the maximum solar-radiation level during the sunny interval of the day and are caller Solar Tracker. The other method is the use of control techniques, applied to a switching converter, that force the module to operate in the optimal operating point, that it’s the Maximum Power Point Tracking (MPPT). The requirements of implementing maximum performance of a photovoltaic system are not only good weather conditions, but also with the appropriate MPPT method. If there is a good irradiance condition, the photovoltaic system can generate maximum power efficiently while an effective MPPT algorithm is used with the system. MPPT techniques considered for this project are fixed-step Incremental conductance, variable-step incremental Conductance and Variable Step size incremental Resistance. A lot of MPPT algorithms have been developed by researchers and industry delegates all over the world. In order to compare the accuracy and efficiency of the three MPPT algorithms selected in this work, The PV simulation system used in this workis set up under Matlab/Simulink environment. The model of PV modules used in PV simulation system is established according to the electrical specifications of the PV module. After accomplishing the model of PV modules, the models of DC-DC Cuk converter and MPPT systems are combined with it to complete the PV simulation system with the MPPT function. The accuracy and execution efficiency of each MPPT algorithm can be obtained by simulating them under different temperature.
