ON-LINE PREDICTION OF PHOTOVOLTAIC OUTPUT POWER UNDER CLOUDY SKIES BY USING FUZZY LOGIC
This paper prescrils an on-linc prediction techniquc oT tlic photovoltaic output power under cloudy skies based on artificial intelligcncc. Thc technique takes advantagc of thc fX1 tlial fuyq logic can aCCUJatCly siinulalc nonlinear phenomena using i set of IF-THEN rules. These rules are fired partially and in-parallcl. This means that, at any time. only a very limitcd subsct of the rules is uscd. This cnablcs I quick, on-linc estimation of the outpul power of lhe photovoltaic cclls bascd on the iinalysis of thc image of tlic cloudy sky.
