Photovoltaic power maximum power point tracking technology based on the fractional-step perturbation observation method
2015
KEYWORD: Solar Power; Maximumpower point ; Track; Perturbation and observation method ABSTRACT: In order to obtain the maximum power output of the solar cell, the output power should be continuously monitored in real time. Based on the traditional perturbation and observation methods, we propose a new algorithm of maximum power point tracking. The method uses the slope of the P-V curve to determine the disturbance step, which improves the tracking performance. Simulation results show that this method is superior performance.
