An Overview of PV Conversion System and MPPT Control Strategies

Solar energy is a renewable energy source (RES), its implementation has a direct positive impact on environment and economic aspects as it minimize the global warming problems and reduce the power transmission cost. Nowadays from RESs the photovoltaic (PV) appears to be the most suitable and successful in producing electricity. This paper reviews in the first hand the most common configurations of PV system and in the second hand the control methods related to maximum power point trucking (MPPT), since the efficiency improvement is the essential parameter to be considered, for that a detailed study has been made to check and compare the Pros and Cons of control methods related to MPPT, the selected ones are Modified Perturb & Observe (MP&O), Artificial Neural Network (ANN) and Particle Swarm Optimization (PSO). They are discussed and compared.
