Method of controlling photovoltaic power generation system |
摘要 |
A conventional hill climbing method is not capable of tracking a maximum power when a shadow covers a part of a solar cell panel and a plurality of maximal values is thereby developed. The invention provides a photovoltaic power generation system control method that controls a photovoltaic output setting value to be an appropriate value by following up a variation in the solar irradiation, including a genetic algorithm process of employing the photovoltaic output setting value as a gene and the output power as an evaluation value thereof; randomly extracting a plurality of genes and repeating storage, selection and crossover/mutation of the output powers which are the evaluation values of the genes, so as to converge a difference between a maximum and minimum values of the output voltages into a predetermined range; and a hill climbing process of setting the photovoltaic output setting value corresponding to the greatest value of the converged output voltages, and a greater and a lower value than the photovoltaic output setting value by a predetermined amount, so as to select the greatest output power among these values; and repeating such steps to track the maximum output power. |
