“…Although the VPSO-LF method increases the search efficiency that is required for off-line complex optimization problems, the combination between the Lévy Flight concept and the random parameters in the velocity equation causes winding of the particles during the online tracking process. Consequently, the Figure. 10: (a) P-V curve and (b) the string power and duty cycle using the proposed method for the pattern (4) winding performance of the particles represents the reason behind the long searching time and the high oscillation in the output power that reduces the root mean square value of the output power and decreases the tracking efficiency.…”

“…Several MPPT methods have been developed to extract the maximum power in the PV system, such as perturbation and observation (P&O) [1], incremental conductance (IC) [2], fractional short circuit current [3], and fractional open circuit voltage [4]. The behavior of the fractional methods depends on a fixed point related to the open-circuit voltage and the short-circuit current of the PV system, respectively.…”

The maximum power point tracking (MPPT) is an essential key to ensure that the photovoltaic (PV) system is operated at the highest possible power generation. This paper presents an efficient MPPT method for the PV system based on an enhanced particle swarm optimization algorithm to track the location of the global maximum power point, whatever its location changes in the search space under all environmental conditions, including the partial shading on strings. In this paper, the formulation of the conventional particle swarm optimization algorithm is enhanced to decrease the searching time and the oscillation of the generated output power as well as the power losses in the online tracking process. This enhancement can be achieved by utilizing a special time-varying weighting coefficient and removing the effect of some other coefficients in the conventional particle swarm optimization algorithm (PSO) that cause winding of the particles during the online tracking process. Test results verified the accuracy of the proposed method to track the global maximum power point with considering the effect of partial shading condition. The proposed method was also compared with other MPPT methods to verify the superiority of the proposed work. The obtained results reveal that the proposed method is effective to improve the tracking efficiency and reduce the tracking time and the number of iterations for the different irradiances and load conditions. The maximum number of iterations was 11 iteration and the highest tracking time was 0.273s with tracking efficiency of about 99.98%.

“…This issue can be resolved by using spare PV panel of same rating which is again not economical. A solution to avoid intermittent shut down is to use semi-pilot cell based FOCV [53,54]. A further improvement in FOCV is done in [49], in which IC as well as FOCV is implemented simultaneously but comparison part is missing.…”

Solar energy is a clean renewable energy and it is available around 89,000 TW on the earth surface. To get maximum power from a solar PV system with minimum power transfer loss is one of the main design objectives of an energy transferring network. Power electronic devices perform a very important character for an efficient PV power tracking system control and either incorporates to transfer the generated power to the ac/dc grid or battery storage system. In this case the duty of the power electronics devices used in PV system is to track maximum power point under different operating conditions of environment, so that power tracking efficiency of solar PV system can be improved. This paper encapsulates based the on performance comparisions on the behavior of MPP under uniform and nonuniform operating conditions and selects the optimum duty cycle for industrially accepted MPPT techniques with their algorithm.

“…Two general challenges of the FOCV method are to improve the accuracy and to reduce the power loss. In this light, this study proposes an improved Fractional Open Circuit Voltage (FOCV) which is an extension to [52]. The main idea is to reduce the power loss during open-circuit voltage measurements by replacing the pilot cell by a semi-pilot cell.…”

This paper proposes two new Maximum Power Point Tracking (MPPT) methods which improve the conventional Fractional Open Circuit Voltage (FOCV) method. The main novelty is a switched semi-pilot cell that is used for measuring the open-circuit voltage. In the first method this voltage is measured on the semi-pilot cell located at the edge of PV panel. During the measurement the semi-pilot cell is disconnected from the panel by a pair of transistors, and bypassed by a diode. In the second Semi-Pilot Panel method the open circuit voltage is measured on a pilot panel in a large PV system. The proposed methods are validated using simulations and experiments. It is shown that both methods can accurately estimate the maximum power point voltage, and hence improve the system efficiency.
