Model construction of single crystalline photovoltaic panels for real-time simulation
ABSTRACT Real-time simulation and fast prototyping with power electronics, critical loads, and control systems have prompted recent interest in accurate electrical terminal models of photovoltaic (PV) panels and array systems. Advancement in computing technologies have allowed the prototyping of novel apparatus to be investigated in a virtual system under wide range of realistic conditions repeatedly, safely, and economically. This paper accesses numerical iteration methods, selects appropriate techniques, and combines them with model construction methods well suited for boosting the computation speed of an electrothermal dynamic model of a PV panel. Significant improvements resulting from the proposed modeling approach in computation time and numerical convergence speed are verified using experimental results published for the target PV panel and Opal RT's RT-Lab Matlab/Simulink based real-time engineering simulator.

ABSTRACT: Use of renewable energy and in particular solar energy has brought significant attention over the past decades. Photovoltaic (PV) power generation projects are implemented in very large number in many countries. Many research works are carried out to analyze and validate the performance of PV modules. Implementation of experimental set up for PV based power system with DC-DC converter to validate the performance of the system is not always possible due to practical constraints. Software based simulation model helps to analyze the performance of PV and a common circuit based model which could be used for validating any commercial PV module will be more helpful. Simulation of mathematical model for Photovoltaic (PV) module and DC-DC boost converter is presented in this paper. The model presented in this paper can be used as a generalized PV module to analyze the performance of any commercially available PV modules. I-V characteristics and P-V characteristics of PV module under different temperature and irradiation level can be obtained using the model. The design of DC-DC boost converter is also discussed in detail. Simulation of DC-DC converter is performed and the results are obtained from constant DC supply fed converter and PV fed converter.IEEE International Conference on Circuit, Power and Computing Technologies - ICCPCT-2014, Tamilnadu, India; 03/2014

ABSTRACT: The article is focused on specific issues arising for a photovoltaic panel (PV). In this case, the short circuit current is measured to determine the value of prescribed current corresponding to maximum power point. The results obtained by imposing a load resistance with this method are energy maximum possible, thus justifying the usefulness of this process very simple and inexpensive applied in practice.Applied Computational Intelligence and Informatics (SACI), 2013 IEEE 8th International Symposium on; 01/2013
