Opis:
An accurate short-term global solar irradiation (GHI) forecast is essential for integrating the photovoltaic systems into the electricity grid by reducing some of the problems caused by the intermittency of solar energy, including rapid fluctuations in energy, management storage, and the high costs of electricity. In this paper, the authors proposed a new hybrid approach to forecast hourly GHI for the Al-Hoceima city, Morocco. For this purpose, a deep long short-term memory network is trained on a combination of the hourly GHI ground measurements from the meteorological station of Al-Hoceima and the satellite-derived GHI from the neighbouring pixels of the point of interest. Xgboost, Random Forest, and Recursive Feature Elimination with cross-validation were used to select the most relevant features, the lagged satellite-derived GHI around the point of interest, as input to the proposed model where the best forecasting model is selected using the Grid Search algorithm. The simulation and results showed that the proposed approach gives high performance and outperformed other benchmark approaches.

Opis:
Solar irradiation is the major source of energy delivered to Earth’s atmosphere. Satellite measurements of total solar irradiation are proportional in time to sunspot numbers. Sunspot numbers have a well-organized periodic nature that is predictable in time. At the present time solar activity is in a very low phase and will be increasing over the next few decades. The atmosphere’s consumption of solar energy strongly depends upon the percentages of carbon dioxide and water vapor in it, which can cause greenhouse effects. The recent increases in the percentage of water vapor and carbon dioxide in the atmosphere have caused global warming. Water levels are affected by melting glaciers. The purpose of this paper is to separate the influence of solar activity and greenhouse effects on global warming and to forecast these influences for several decades.

Opis:
Estimation of Global Tilted Irradiation (GTI) is a key to performance assessment of typical solar systems since they usually employ tilted photovoltaic (PV) modules or collectors. Numerous solar radiation databases can deliver irradiation values both on horizontal and tilted plane, however they are validated mostly with horizontal-plane ground measurements. In this paper we have compared GTI estimates retrieved from five Internet databases with results of measurements at two PV systems located in Poland. Our work shows that in spite of good agreement in annual scale, there is a tendency to underestimate GTI in summer and overestimate in winter, when PV modules can receive less than a half of expected irradiation. The latter issue affects sizing of PV system components and implies a correction needed to achieve all-year long operation.
