Note also that in figure 4 (b) the probability of observing ±4000 MW fluctuations of solar power in 60 min is two orders of magnitude higher than that of wind power for nearly the same rated power in Germany.

The most recent studies consider the fluctuations in wind and solar powers in 15 or 60 min and investigate the effects of these fluctuations in power system [14, 15] and the trading on the electricity market [15 – 17]. However, up to now, little work has been done in connection with disentangling the time dependency of these fluctuations.
These fluctuations result from natural weather cycles and stochastic variations, causing annual solar radiation to deviate by a few percent from the mean. Understanding interannual variability is essential for developers and investors to assess the reliability and predictability of solar resources over the long term.
The power output of PV sources fluctuates due to changes in weather conditions, rain fall, and movement of clouds. The primary reason for this fluctuation is cloud movement. Given below are some of the issues of PV output power fluctuation caused by cloud movement as reported by investigators:
The electricity production from PV sources directly depends on the intensity of sunlight. When connected to the grid, PV and wind power have a positive impact. However, they can also influence electricity production negatively.
It is found that power fluctuations are significantly suppressed in photovoltaic (PV) sources, but they cannot smooth short-term fluctuations effectively. When the number of PV systems decreases, it contributes to an increase in fluctuations. In the short term, the output power fluctuation of a geographically dispersed PV system is reduced compared to individual PV systems.
