چکیده

ABSTRACT


This paper presents the development of methods and mathematical models to determine the DC/AC average efficiency of inverters that allow to optimize estimates of electricity generation of photovoltaic systems. The adaptive hybrid mathematical model of DC/AC average efficiency of inverters of photovoltaic systems proposed in this paper may be composed of three function settings–Linear, Lognormal, and Polynomial–considering the influence of the relative power, which varies with the sizing factor inverter and the DC input voltage. Determining of the average efficiency with a high degree of accuracy guarantees greater reliability in estimating electricity generation of photovoltaic systems. Depending on the specific behavior of each model and topology of inverter, the adaptive hybrid mathematical model determines the fit functions with highest coefficient R2 , and estimates with accuracy the DC/AC average efficiency that represents the operation and dynamic behavior of the inverters.

Conclusions


In particular, it was developed and presented an adaptive hybrid mathematical model that considers the influence of the relative power, which varies with the SFI and the DC input voltage to the South of Brazil radiation profile. From the fit functions for each manufacturer and topology of the inverter, it was possible to develop dynamic maps that represent the behavior of the DC/AC average efficiency of operation under different conditions of SFI and DC input voltage. The determination of the average efficiency with a high degree of accuracy and precision guarantees greater reliability in the estimation of electricity generation of photovoltaic systems. From the results it was verified that the average efficiencies determined in this study have efficiencies ranging between 1% and 2%. The adaptative hybrid mathematical model allows precision and accuracy to determine the DC/AC average efficiency of inverters of photovoltaic systems.
