The invention patent provides a method for modeling the photovoltaic output stochastic model reflecting the characteristics of solar radiation intensity changes, including the following steps: determining the characteristics of solar radiation intensity changes; establishing a solar radiation intensity model that takes into account the characteristics of solar radiation intensity changes; establishing the output power of the photovoltaic array model.
The photovoltaic output model established by the invention can not only reflect the regularity of the photovoltaic output with seasonal changes and alternating days and nights, but also reflect the volatility and uncertainty shown by weather and other factors, making the photovoltaic output more realistic.
