Our results highlight how reliability analysis must account simultaneously for the mean and intermittency of solar inputs when assessing the impacts of climate change on photovoltaics.
Generally speaking, there are two main methods for the short-term power output forecasting of PV system: indirect forecasting method and direct forecasting method. The indirect forecasting method firstly forecasts the solar radiation intensity and then the short-term power output is given based on the physical model of the PV power plant [ 3 – 5 ].
We find that the relation between the future power supply and long-term mean solar radiation trends is spatially heterogeneous, showing power reliability is more sensitive to the fluctuations of mean solar radiation in hot arid regions.
The intermittency of solar resources is one of the primary challenges for the large-scale integration of the renewable energy. Here Yin et al. used satellite data and climate model outputs to evaluate the geographic patterns of future solar power reliability, highlighting the tradeoff between the maximum potential power and the power reliability.
