Embodiment Construction
[0032] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0033] Such as figure 1 As shown, a method for predicting photovoltaic power generation based on support vector machine regression is disclosed, which includes the following steps:
[0034] Step 1, obtaining historical output data and numerical weather forecast data of the target station;
[0035] Step 2, analyzing the relationship between the output data of the target station and the meteorological parameters of the numerical weather forecast, and screening out the meteorological factors with strong correlation, and the meteorological factors include radiation intensity, cloud cover, temperature and humidity;
[0036] Step 3, preprocessing the historical data set, mainly filtering out unreasonable sample values, and at the same time ve...
