Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
The power-voltage (P-V) characteristics of a photovoltaic (PV) array exhibit multiple peaks under partial shading conditions (PSC). The classical 0.8V-model-based maximum power point tracking (MPPT) method assumes that the peaks are located at multiples of the 0.8V (open-circuit voltage). The global maximum power point (GMPP) is obtained after comparing the power of these voltage regions. In this paper, the proposed method reduces the comparison process and the voltage region can be determined based on the shading information. The improved performance of the proposed method has been verified using Simulink. The simulation results demonstrate that the proposed technique is feasible and efficient in comparison with the classical 0.8V-model-based method.
