The Linear Model of a PV moduel

Abstract

<p>This paper propose a new approach to determine a linear mathematical model of a PV moduel based on an accurate nonlinear model . In this study, electrical parameters at only one operating condition are calculated based on an accurate model. Then, first-order Taylor series approximations apply on the nonlinear model to estimate the proposed model at any operating conditionts. The proposed method determines the number of iteration times. This decreases calculation time and the speed of numerical convergence will be increased. And, it is observed that owing to this method, the system converged and the problem of failing to solve the system because of inappropriate initial values is eliminated. The proposed model is requested in order to allow photovoltaic plants simulations using low-cost computer platforms. The effectiveness of the proposed model is demonstrated for different temperature and irradiance values through conducting a comparison between result of the proposed model and experimental results obtained from the module data-sheet information.</p>

Joule heating estimation of photovoltaic module through cells temperature measurement

“…However, these models also depend on the accuracy of the environmental and operational data. Artificial intelligence (AI) techniques with artificial neural network (ANN) [18]- [20], modelling with various models [21]- [23] are satisfactory in estimating the PV module temperature. However, all these techniques have not demonstrated the physics interaction of input parameters, such as environmental and operational data.…”

Mathematical Modeling of Photovoltaic Thermal-Thermoelectric (PVT-TE) Air Collector

“…To overcome the limitation of conversion efficiency of PV cell, photovoltaic thermal (PVT) was introduced which is the most commonly used method for active cooling that provide both thermal and electricity simultaneously [12], [13]. Beside that, by modifying the nonlinear I-V calculation which includes open circuit, extreme power and short circuit, the theoretical and simulation approach of the photovoltaic cell by Matlab-Simulink Situation can be evaluated to get a better performance [14], [15].…”
