COMPARISON OF PRONY AND ADALINE METHOD IN INTER-HARMONIC ESTIMATION

Abstract

Especially in energy and power systems, harmonic estimation has crucial role. Many techniques developed in the subject of harmonic and inter-harmonic estimation. These techniques and methods include mathematical transformation (Fourier, Hartley, Hilbert-Huang, etc.) filters (adaptive, Kalman, etc.) and parametric methods (Prony, ADALINE, MUSIC, etc.) In realized study, performance of ADALINE and Prony methods are investigated in terms of harmonic and inter-harmonic prediction capability. Required data for simulations are produced from P&O MPPT algorithm for photovoltaic systems. Therefore, this model gives opportunity to try compared methods according to different harmonic intensity (closeness of harmonics to each other). At the result of different simulations, it is observed that Prony method is more preferable for low number of data and ADALINE produces more successful results than Prony method if there is high number of data and selection of high neuron size relatively.
