The typical daily solar generation curve and load curve, as shown in figure 1, are derived from solar radiation and load supply data. Area 1 represents the user's power purchase, area 2 represents power exported to the grid, and area 3 represents solar generation used locally.
Figure 1 shows PV generation in watts for a solar PV system on 11 July 2020, when it was sunny throughout the day and on 13 July when there was a mixture of sun and cloud. A south facing solar PV system will tend to generate more around noon.
Solar PV generation is higher in the summer than the winter due to longer days and the sun being higher in the sky. Figure 4 shows the typical monthly values of solar PV generation for a 2.35kW solar PV system in London which faced 60 degrees from south. From year to year there is variation in the generation for any particular month.
Prediction of photovoltaic power generation can effectively mitigate the influences of meteorological and other factors on solar power stations, thereby enabling the efficient deployment of solar energy resources in China.
A solar PV system on the south coast of England for example will generate more electricity annual than one of a similar size, orientation and inclination in the north of Scotland. A solar PV system on the south coast of England for example will generate more electricity annually.
Leveraging the NEX-GDDP-CMIP6 data, the study constructed the Vine Copula multi-model ensemble downscaling model. On this basis, the future power generation of PV power station for 2025–2034 was predicted using the future meteorological data provided by the downscaling model. Both models constructed for the PV power station have high accuracy.
