A Novel Photovoltaic Cell Simulator for Green Internet of Things

摘要

This paper designs and implements a new type of photovoltaic cell simulator based on LabVIEW platform, which is used to simulate the output I-V characteristics of photovoltaic cells. The main contribution of this work is the implementation of the point-by-point comparison algorithm, which is used to control the power supply of a photovoltaic cell to follow a given I-V output curve on the LabVIEW platform. The experimental results show that the photovoltaic cell simulator can achieve 96% accuracy, and can be used as a reliable tool for the simulation of the MPPT (Maximum Power Point Tracking) algorithm and the analysis of power supplies of sensor nodes in green internet of things.
