description The invention relates to a prediction method and system for starting capacity of a photovoltaic power station, and belongs to the technical field of renewable energy power generation. The prediction method for the starting capacity of the photovoltaic power station comprises the steps of firstly selecting a similar day according to weather forecast of a prediction day and historical weather data of a sample day; secondly according to the occurrence time of a start-stop event of each inverter in the similar day, performing probability statistics to obtain probability distribution of the start-stop event of each inverter in the prediction day and probability distribution of a starting rate corresponding to solar radiation intensity; and finally according to a start-stop state of each inverter and capacity, calculating the starting capacity of the photovoltaic power station in the prediction day. The predicted starting capacity better meets a real condition and is more accurate; the method is simple and easy; da
