Hybrid energy harvesting system using IOT

Abstract

Global warming, environmental pollution and power production costs are the major issues that the world is facing and many research work is done in the above areas to reduce the adverse effects arises due to fore mentioned issues. In particular, many research has been carried in power generation without CO2 emission and polluting the environment. This can be achieved by using renewable sources for electrical energy production in optimized manner. This paper presents a hybrid energy harvesting by combining thermoelectric Generators (TEG) along with solar energy to develop electrical energy. The proposed framework has been intended to harvest energy to an extent that it can gather both solar energy and the heating effect in the panel at the same time. The solar radiations are made to fall on the PV panel, which is productive enough to collect the light radiations falling on it and convert into electrical energy. Meanwhile, these radiations cause warming up of the PV panel, prompting the decrease in its effectiveness of production. Hence in order to increase the efficiency of the system energy harvesting, this heat production is utilized using TEG. The thermoelectric generators are used which retain this warmth and create an electrical energy in the form of DC based on seebeck effect. This project utilize a PV panel and a thermoelectric generator to incorporate both light and warmth for harvesting electrical energy. This output energy is needed to regulate with the help of dc-dc converter. The contribution of energy from PV panel and thermoelectric generator are given to the buck boost converter. The output of the converter is stored in the battery which can be used for direct dc load or through inverter for ac load. This project also implements internet of things (IOT) technology to monitor and manage the electric energy harvested through this technology from anywhere.
