Maximum Power Point Tracking of Solarex MSX PV Module System using FLC

Abstract

Maximum power point tracking (MPPT) is a technique that grid tie inverters, solar battery chargers and similar devices use to get the maximum possible power from one or more solar panels. In this paper the simulation result of the P&O algorithm and the conventional maximum power point tracking technique compared with Intelligent Control (fuzzy logic controller-FLC). In fact the target of this manuscript is study the effect of the environmental conditions like variation of solar intensity and temperature on output power of photovoltaic module. Solarex MSX-83 PV module and MATLAB/SIMULINK software are used for simulation. In this paper, the construction of stand-alone photovoltaic system consists of PV module, boost converter, maximum power point tracker and Pulse Width Modulator.

Design of a fuzzy current‐sensor less maximum power point tracking algorithm for photovoltaic systems

“…The fuzzy control stage is a procedure to generate the value and direction of the converter duty‐cycle step‐size using the input data and [1, 19]. At the input layer of this controller, the crisp input data pairs change to the fuzzy values using the input MFs.…”

Fuzzy Logic Based Maximum Power Point Tracking Using Boost Converter for Solar Photovoltaic System in Kuwait

“…The PV array characteristic shows that this derivative is positive to the left of the maximum power point and negative to the right of maximum power point [4,9]. This leads to the following set of equations: …”

“…The most widely MPPT techniques available in the literature [4][5][6][7][8][9][10][11] can be summarized as:…”

“…Until now different MPPT algorithms are studied [4][5][6][7][8][9] using conventional PID controller to adjust the duty cycle of the DC/DC boost converter. FLC has been implemented on real-time control system and results in good performance even for nonlinear and time-varying system [7][8][9].…”

“…FLC has been implemented on real-time control system and results in good performance even for nonlinear and time-varying system [7][8][9]. Due to its simplicity and easy to implement, this paper developed FLC based on P&O and IC algorithms for obtaining the maximum power output of photovoltaic array under different weather conditions in Kuwait.…”
