Global maximum power point tracking algorithm based on improved flower pollination

The invention relates to a global maximum power point tracking algorithm based on improved flower pollination. The algorithm comprises the following steps: initializing parameters, calculating the duty ratio of the pollen gamete of which the number is K and the output power of the corresponding photovoltaic array, and searching for the duty ratio corresponding to the maximum power point as the global optimal value of the current time; comparing the uniform random number with the conversion probability, if the uniform random number is greater than the conversion probability, performing global search, otherwise, performing local search; and calculating the output power corresponding to the next-generation duty ratio, calculating the fitness corresponding to the next-generation duty ratio, respectively comparing the fitness corresponding to the next-generation duty ratio with the fitness corresponding to the current-generation duty ratio and the initial fitness, determining whether the next-generation duty ratio
