Effect of Maximum Power Point Tracking in Photovoltaic Systems and Its Improving and Its Application of Wireless Energy Transmission

Despite the advantages of photovoltaic (PV) modules such as noiseless operation, being fuel-free and non-polluting, the most important factors hindering their wide use are high investment costs and low energy conversion efficiencies.By reason of that, studies involving efficiency improvement of the systems fed by PV energy is deemed important.In recent years, studies about PVs have focused on minimize the costs and maximize the conversion efficiency.In order to maximize the efficiency of PV energy conversion systems, solar panels and arrays should be operated at maximum power points (MPP).At MPP, solar arrays generate the electric energy at maximum efficiency and minimum losses.Solar cells have variable current and voltage characteristics and MPP depends on solar irradiations and ambient temperature.So a maximum power tracking control should be made rapidly in different temperature and solar radiation conditions.In this study; solar cell was obtained by using equivalent circuit of solar cell with Matlab / Simulink and by using this structure , a PV generator was designed which is not only used with boost dc / dc convertor but also used with MPPT (maximum power point tracking) unit.Besides due to its easy implementation, P&O (Perturb-Observe) which is the most common algorithm in PV systems is originally modified for oscillation problem and chosen the design of the MPPT.Finally, wireless energy transmission was applied in conventional and using MPPT PV system on experimental setup for comparing.
