Maximum power point tracking (MPPT) algorithms are used in photovoltaic applications to extract the maximum power that the photovoltaic (PV) panel can produce, which depends on two inputs that are: temperature and irradiance. A DC-DC converter is inserted between the photovoltaic panel and the load to obtain the desired voltage level on the load side. In this paper, incremental conductance (INC) algorithm, modified INC, and fuzzy logic controller (FLC) are designed and assessed to improve energy conversion efficiency. These algorithms are applied to the control of boost converter for tracking the maximum power point (MPP). The modified INC offers fast response and good performance in terms of oscillations than conventional INC and FLC. The Matlab/Simulink environment is used to analyze, interpret the simulation results, and show the performances of each algorithm; and Proteus-based Arduino environment is used to implement the three methods in order to compare the Matlab simulation results with measurements acquired during implementation that is similar to real experiment.

The main importance of solar photovoltaic energies research is to meet the many environmental demands of the energy challenge, to maximize power and to reduce the costs of photovoltaic (PV) systems to reply the energy needs of population. In the present research work, the first objective is to study the performance and the output energy can be produced by a photovoltaic panel installed in the parking of Ibn Tofail University at Kenitra-Morocco. These provide the basis for developing a simple and efficient model for the PV panel electrical behavior. As the output powers of photovoltaic system are influenced of the solar irradiances (G) and cell temperature (T); the effects of varying the two variable factors, series and shunt resistances, and partial shading on the output of the PV system are presented. Then, the PV system is connected to three phases grid using Boost converter controlled by the perturb and observe technique of Maximum Power Point Tracking and using the DC-AC inverter. The Matlab/Simulink software is used to model the system and to show the simulations result.
