Abstract

This work presents an analysis on the integration of energy harvesting technologies used for low power applications. The main goal e is to develop a simulation platform representing a nanogrid using the consolidated models of three of the most mature energy harvest sources: photovoltaic, thermoelectric and piezoelectric. The resulting model is used to evaluate the advantages of adding energy harvesters to a battery supplied applicaiton. It will be presented a short literature review, as well as a discussion about equivalent circuit models for each one of the sources used on the proposed 100 mW nanogrid. Aspects regarding modelling and simulation of the system on PSIM is presented and some case studies are performed to validate the proposed methodology.
