## Hybrid Neural Network Incremental Conductance MPPT in MATLAB

## Introduction

The Maximum Power Point Tracking (MPPT) is an essential part of any renewable energy system to ensure maximum efficiency. One of the most popular and effective methods for MPPT is the Incremental Conductance (IC) algorithm. However, the IC algorithm requires accurate measurements of the derivative of the power with respect to voltage, which can be challenging in noisy environments. In recent years, Hybrid Neural Networks (HNN) have been proposed as a solution to this problem. In this article, we will discuss how to implement the HNN IC algorithm in MATLAB.

## The Incremental Conductance Algorithm

The Incremental Conductance algorithm is a popular and widely used MPPT technique. It works by comparing the instantaneous conductance of the solar panel to a reference conductance. When the two conductances are equal, the system has reached the maximum power point. The algorithm then adjusts the duty cycle of the DC-DC converter to maintain the maximum power point.

The Incremental Conductance algorithm requires accurate measurements of the derivative of the power with respect to voltage. This can be challenging in noisy environments, and the algorithm may oscillate around the maximum power point. To overcome this problem, a Hybrid Neural Network can be used.

## Hybrid Neural Network

A Hybrid Neural Network combines the advantages of both artificial neural networks and traditional control techniques. The neural network can learn and adapt to the system's behavior, while the traditional control technique can ensure stability and robustness.

The Hybrid Neural Network Incremental Conductance algorithm uses a neural network to estimate the derivative of the power with respect to voltage. The neural network takes as input the current and voltage of the solar panel and outputs the estimated derivative. The neural network is trained using the backpropagation algorithm.
