“…It is preferred due to its simple structure. P&O algorithm is a useful MPPT algorithm as far as PV energy conversion where changes in sunlight radiation are constant or slowly atmospheric conditions [12], [13]. This problem can be solved to decrease the perturbation step; but, the tracking response will be slower.…”

Abstract-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.Index Terms-DC / DC converter, MPPT, P&O algorithm, PV panel, wireless energy transmission.

“…In the literature, both converter design and MPPT algorithms have been studied and presented so far. To reach maximum power point faster, several algorithms such as Perturbation and Observation (P&O) [13], [14], incremental conductance [15], look-up table [16], [17], current control loop [18] were proposed and applied.…”

Abstract-The performance of photovoltaic (PV) system is affected by temperature, solar insolation, solar panel configuration and shading. In order to succeed maximum efficiency, PV arrays should operate at their maximum power point (MPP). Hence, the MPP tracking (MPPT) unit is implemented among the PV energy conversion system to obtain maximum power. In this study, incremental conductance (IC) algorithm, the most commonly used algorithm in MPPT systems for expectation-maximization, was analysed and an approach towards eliminating ripple problems, improving speed to obtain more power value, were maintained and duty cycle (Dk) value was obtained from IC algorithm under changing PV panel radiation conditions. In the end, it was evaluated alongside with MATLAB simulation results.Index Terms-Photovoltaic (PV) cell, incremental conductance, maximum power point tracking (MPPT), boost DC/DC converter.
