| Popis: | 31st European Photovoltaic Solar Energy Conference and Exhibition; 3112-3116 Load duration curve (LDC) and output duration curve (ODC) are a very useful graphic tools to analyze the behaviour of an electric system both for demand purposes and for generation ones, respectively. Despite that, the use of this tool is not much extended in photovoltaics systems, not even in grid connected PV systems. However, its utilization may provide us with interesting information for the assessment of the PV system operation, such as: peak power reached, energy yield, energy time distribution, etc. Therefore this type of curves can be very useful both for the analysis of the PV system operation and for the comparison among different PV systems or to perform studies related to energy planning and grid penetration of PV electricity. Regarding the latter issue, it is presented how the use of ODC can determine the maximum demand coverage through photovoltaics in large electricity grids. In the cases studied, the maximum photovoltaic coverage has resulted to range between 18.7% and 29.9% of the annual energy demand without including storage and without surplus photovoltaic generation. An interesting new concept is presented: Half Energy Line. This line can be successfully used to analyze the behaviour of a photovoltaic installation or system. |
