Here the authors find that solar and wind power resources can satisfy countries’ electricity demand of between 72–91% of hours, but hundreds of hours of unmet demand may occur annually.
In this paper, a novel multi-prediction method is proposed for short-term electric load and photovoltaic solar power forecasting in GPVS. In the proposed framework, a non-parametric FPCA is firstly constructed to extract features and realize low parameter sensitivity so as to achieve great stability performance.
In order to describe this correlation more accurately, we need to establish a model for the correlation between load and output of renewable energy generation. This paper uses kernel density estimation to model the source charge, using kernel density theory and Copula theory to analyze the static correlation between source output and load.
When solar PV and storage are considered simultaneously, the concurrent shift in the net load profile suggests a symbiotic relationship: storage can be dispatched during hours when solar exhibits diminished output, and solar helps to shorten the durations of peak load that must be shaved by energy-limited storage systems.

6 FAQs about [Solar power generation and load relationship]
How is solar power forecasting based on daily electric load and photovoltaic power?
In each benchmark, according to references [ 13, 14 ], the daily electric load and photovoltaic solar power data from 2019 to 2020 are randomly split into a training set and validation set with the percentage of 90% and 10%, respectively, while 2021 is used to test the prediction performance.
How does forecasting of solar energy and load variations improve cost-effectiveness?
The model output has been presented in root mean square error and mean absolute percentage error. The results exhibit a improved concurrence between the forecasted and real models. The forecasting of solar energy and load variations assists in fulfilling the cost-effective aspects.
Can photovoltaic solar power be integrated into power grid?
Performance analysis including stability and feasibility is conducted. In the grid-connected photovoltaic system (GPVS), due to characteristics of fluctuation and intermittency for photovoltaic solar power, and high randomness for electric load, it is of great difficulty for integrating photovoltaic solar power into power grid.
How can solar and wind power meet global electricity demand?
With solar and wind capacities sized such that total annual generation meets total annual demand, seasonal and daily complementarities of these resources make them capable of meeting three-quarters of hourly electricity demand in larger countries.
Does light intensity affect the performance of solar energy generation?
In the experimental study of the influence of light intensity on the performance of solar energy generation of trough photovoltaic cells, the trough concentrated photovoltaic power generation system with high cost performance is used, as shown in Figure 2. Trough type concentrating photovoltaic power generation system.
What factors affect solar power generation?
Because key factors such as sudden movement of the clouds, instantaneous deviation of temperature in ambiance, the increased proportion of relative humidity and uncertainty in the wind velocities, haziness, and rains cause the undesired up and down ramping rates, thereby affecting the solar power generation to a greater extent.
