Modelling and Parameter Estimation of Solar Cell using Genetic Algorithm

Abstract

In renewal energy hole worlds go towards the solar energy source. In this paper, we derive the mathematical relationship of single diode configuration and do mathematical modelling in MATLAB Simulink. And get the output waveform of current- voltage and power voltage at different temperature and irradiance value. Analysis the effect of variation in temperature and irradiance on a solar cell. After we do the parameter estimation of solar cell using genetic algorithm (GA). Using GA, we estimate the five parameters (I <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ph</inf> , I <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</inf> , n, R <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</inf> and R <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sh</inf> ) form the single diode configuration of PV cell. After estimation we try to extract the five unknown parameters (I <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ph</inf> , I <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</inf> , n, R <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</inf> and R <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sh</inf> ) of module Kyocera (KC200GT) using genetic algorithm and compare the output power using different methods. We also compare the output power with the initial parameters and extracted parameters.
