TIME FRAME MEASUREMENTS IMPACT ON PROBABILISTIC BEHAVIOUR OF PHOTOVOLTAIC SYSTEMS

Autor/autori: Professor Giuseppe Marco TINA, Professor Gilles NOTTON, Lecturer Ciprian NEMES,

Rezumat: Pentru un sistem electric cu panouri fotovoltaice este important sa se evalueze si sa se inteleaga modul in care intervalele de masura a radiatiei solare pot afecta capacitatea sistemului de a genera si de a acoperi necesarul de sarcina. Nivelul puterii generat de un sistem fotovoltaic se evalueaza pe baza valorilor medii orare ale gradului de nebulozitate. Obiectivul principal al acestei lucrari este de a evalua efectele diferitelor intervale de masura a radiatiei solare asupra indicatorilor de adecvabilitate ai unui sistem ce integreaza surse fotovoltaice.

Cuvinte cheie: energie solara, nebulozitate orara, indicatori de adecvabilitate


Abstract: For a generation system including photovoltaic systems is important to assess and understand how different time frames for the irradiation measurements can impact the ability of the system generating capacity to meet the total system load. The electrical output power generated by a photovoltaic system is evaluated using the hourly average clearness index values. The main objective of this paper is to evaluate the effects of different time frames, over that the measurement data are recorded, on the probabilistic behaviour of a grid-connected photovoltaic system.

Keywords: solar energy, hourly clearness index, adequacy indices
