[IEEE 2018 IEEE PES/IAS PowerAfrica - Cape Town (2018.6.28-2018.6.29)] 2018 IEEE PES/IAS PowerAfrica - Estimation of Global and Direct Solar Radiation in Tunisia Based on Geostationary Satellite Imagery
摘要： Available solar radiation is an important source of renewable energy that determines Tunisia’s productivity but has been poorly characterized. Measured solar radiation datasets are generally not available for long periods. This paper studied the method of estimates for solar radiation based on satellite imagery and on the measured data by the national institute of meteorology. Data collected from the year 2015 in three different locations in Tunisia. The objectives of this study are: a) Assess of monthly global solar radiation using data of meteorology for three stations. b) Compare measured data with two different geostationary satellites imagery in order to validate the good estimation of the satellite imagery. c) Reduce the uncertainly of the use of satellite imagery long-term solar resource by validate the estimated data with those measured by the pyranometer from the meteorological station.

Risk analysis using meteorological weather factors in solar energy conversion systems
摘要： We propose a methodology for conducting simulations of operational scenarios for energy projects based on photovoltaic generation systems. It considers several documented facts about time series of weather, such as strong seasonality and structural breaks, which the previous literature has not explored in depth. Our proposal uses public weather time series, which are usually recorded by meteorological observatories. This makes our approach a suitable strategy for any firm interested in applying it to its own data and projects. This approach also allows the user to set an appropriate level of confidence for the scenarios depending on her interests.
