Evaluation of Hybrid Energy Storage Systems Using Wavelet and Stretched-Thread Methods

Abstract

This paper presents a methodology to evaluate hybrid energy storage systems in hybrid energy systems. While Wavelet is used to decompose the net load in temporal segments, the stretched-thread method is used to evaluate the influence of energy storage, instead of conventional optimization techniques, conferring a visual approach. Proper selection of energy storage technologies for each time frame, as long as several sizing of different energy storage technologies is evaluated as well. The use of different methods and their application in a hybrid system are the main contributions of this piece.
