Data Envelopment Analysis and Fourier Series Integrated Use: The Case of The Harmonic Distortion Evaluation

Abstract

The electrical energy must be suplied in enough amount but with adeaquate quality. One of the components of electrical energy quality is the harmonic distortion. In this paper, we show an alternative way to measure distortion, mixing Data Envelopment Analysis (DEA) and Fourier Analysis. The technique here presented is especially useful for comparative analysis.
