- Abstract
Output power of photovoltaic cells is greatly related with light intensity and temperature, in order to achieve maximum output power, it is necessary to implement maximum power point tracking (MPPT).This paper analyses misjudgments, oscillations and energy loss during MPPT by fractional Open-Circuit Voltage method, perturbation and observation method, incremental conductance method. An improved perturbation and observation method is proposed to reduce oscillations and energy loss and improve the speed and accuracy of tracking.
