Abstract
A method including: acquiring present output current values of photovoltaic strings included in a photovoltaic array that, wherein includes at least two photovoltaic strings in parallel; determining a target abnormality score predicting model based on the present output current values. Determining a present abnormality score corresponding to the photovoltaic array by inputting the present output current values into the target abnormality score predicting model; and determining the operating state of the photovoltaic array by comparing the present abnormality score with a target abnormality score. The present abnormality score is output by inputting the present output current values acquired in real-time into the abnormality score predicting model, so as to determine the operating state of the photovoltaic array.
