Design and Analysis of Hybrid Energy System

Abstract

This paper presents a study on of hybrid solar and wind energy systems behaviour, which allows employing renewable and variable in time energy sources with a continuous supply. Solar energy is not a revolutionary technology by any means and has long been criticized for its inefficiency and other shortcomings. "What do we do when the sun goes away every night"? Well with batteries, of course! But it's not that simple, the battery currents and voltages need to be regulated to provide optimum power transfer to the client because efficiency reduces cost and high cost is the last major road block in making solar &wind feasible energy alternative. The heart of our product then is microprocessor control of the stored energy. The approach taken was essentially an embedded systems approach. We needed to interface the microprocessor, with some current/voltage limiting hardware, a voltage regulator, relay, and various other necessary components to effectively read the currents coming off the panels and entering the batteries, and those currents leaving the batteries to power some desired application.
