Scaled Conjugate Gradient Artificial Neural Network-Based Ripple Current Correlation MPPT Algorithms for PV System

A conjugate gradient based method for Decision Neural Network training

Decision Neural Network is a new approach for solving multi-objective decision-making problems based on artificial neural networks. Using inaccurate evaluation data, network training has improved and the number of educational data sets has decreased. The available training method is based on the gradient decent method (BP). One of its limitations is related to its convergence speed. Therefore,...

A Single-Phase Multilevel PV Generation System with an Improved Ripple Correlation Control MPPT Algorithm

The implementation of maximum power point tracking (MPPT) schemes by the ripple correlation control (RCC) algorithm is presented in this paper. A reference is made to single-phase single-stage multilevel photovoltaic (PV) generation systems, when the inverter input variables (PV voltage and PV current) have multiple low-frequency (ripple) harmonics. The harmonic analysis is carried out with ref...

Scaled Conjugate Gradient Learning for Quaternion-Valued Neural Networks

An Accurate ANFIS-based MPPT for Solar PV System

It has been found from the literature review that the ANFIS-based maximum power point tracking (MPPT) techniques are very fast and accurate in tracking the MPP at any weather conditions, and they have smaller power losses if trained well. Unfortunately, this is true in simulation, but in practice they do not work very well because they do not take aging of solar cells as well as the effect of d...

Edge Detection Using Scaled Conjugate Gradient Algorithm in Back Propagation Neural Network

This paper introduces a proposed method based on a backpropagation artificial neural network using Scaled Conjugate Gradient (SCG) training algorithm so as to gain the edges of any image. A new training image model is suggested to train this artificial neural network, then using this network to find the edges of any image. Computer experiments are carried out for extracting edge information fro...
