Resumen
MAXIMUM POWER POINT TRACKING (MPPT) METHODS HAVE BEEN WIDELY DISCUSSED IN MANY RESEARCHES TO IMPROVE THE EFFICIENCY OF THE ENERGY EXTRACTION FROM SOLAR CELLS. ON THE OTHER HAND, TO CONTROL PROCESS THE MOST COMMON WAY IS TO FIND A MODEL, WHERE THE PARAMETERS ARE ADJUSTED IN ORDER TO ACHIEVE SIMILARITY BETWEEN THE MODEL AND THE REAL PLANT. SOLAR CELLS HAVE BEEN MODELED BY NONLINEAR EQUATIONS THAT ALLOW TO APPROXIMATE THE STATIC BEHAVIOR. HOWEVER, THE PARAMETERS EVOLVED IN THESE EQUATIONS DEPEND UPON THE CONSTRUCTION AND THE TYPE OF SOLAR CELLS. THUS, THIS PAPER PROPOSES A PARAMETER IDENTIFICATION WITH A NEW SIMPLIFIED METHOD TO IDENTIFY THE PARAMETERS N, RS AND I0, BY STUDYING AND ANALYZING THE EQUATIONS OF THE PV MODEL AND THE INFORMATION PROVIDED BY THE DATASHEETS OF THE BEST-SELLING COMMERCIAL PV PANELS IN THE WORLD.
