Modelling and Simulation of Double Diode Model of PV Cell by Using LtSpice

Abstract

This research provides a systematic analysis of the PV cell modeling for simulation studies. The primary aim of this analysis is to examine the findings and compare them under normal test conditions. In order to extract the maximum possible power, PV model parameters are find using mathematical analysis and manufacturer’s datasheet. Therefore, it is vitally important to determine maximum power point (MPP) location for the implemented model. Other criteria for finding the right model for use in simulation should also be considered. Choosing the right model based on the application is very critical. Double-diode model was used to study the characteristic of the PV cell and to simulate the model, LtSpice software has been chosen. Under various temperature and irradiance conditions, several work tests have been carried out to investigate the performance of the PV model. The double diode model is known to have better accuracy at low irradiance levels, allowing the performance of the PV model to be predicted more accurately.
