Research Article Parameter Optimization of Single-Diode Model of Photovoltaic Cell Using Memetic Algorithm YourimYoon 1 andZongWooGeem 2 Department of Computer Engineering, Gachon University, Seongnam Daero, Seongnam - , Republic of Korea endobj Abstract: In this study, the cell behavior in a photovoltaic (PV) module will be investigated by using two electrical characteristics models of mono-crystalline solar cells: (i) the single diode model, and (ii) the double diode model. Of course, the standard equivalent circuit is a simplified model of a solar cell, aiming at a lumped description that may provide an interpretation of measured current--voltage characteristics. Basic (One-Diode) Model of a PV Cell Remembering that a photovoltaic cell is just a special kind of semiconductor diode, if we want to figure out the total current flowing, we can just add (or in this case, subtract), the diode current from the photoelectric current. Fig.1(a) shows the symbol of solar cell in SimElectronics, Fig.1(b) shows the equivalent circuit. Abstract In this paper, all the models of PV cell, namely ideal single-diode model, single-diode Rsmodel, single-diode Rpmodel, the two-diode model, and the three-diode model, have been discussed.

IPH refers to the photo-generated controlled current. single diode model. It means that for any type of PV module, one can use this model and determine all the necessary parameters under any new conditions of irradiance and … Single and double diode PV models have been widely used for modelling the output characteristic of a PV module [8]. A flowchart has been made for estimation of solar cell output current, for single diode and two diode model, using Newton-Raphson iterative technique which is then programmed in MATLAB script file accordingly. This model is based on the following equivalent circuit for decribing a PV cvell: The model was primarily developed for a single cell. The model for PV panel is developed based on the sin-diode gle photovoltaic model, found in the literature, including the effect of the series resistance. However, the model characteristic equation which is implicit in nature makes the … A PV module refers to a number of cells connected in series and in … The output power prediction by a photovoltaic (PV) system is an important research area for which different techniques have been used.
