This paper presents a study on a stand-alone photovoltaic (PV) system to provide the required electricity for a single residential household in Sinai Peninsula of Egypt. The complete design of the suggested system is carried out, such that the site radiation data and the electrical load data of a typical household in the considered site are taken into(More)
The aim of this paper is to design a textual display system, based on a light emitting diode (LED) dot matrix array powered by solar energy. The paper involves taking the device from an initial concept, through a design phase, to constructing a prototype of the product. The system consists of the display unit, which is powered from a photovoltaic ( PV)(More)
In this paper an operational control technique, based on using the fuzzy logic controller (FLC), is developed and applied to a proposed Photovoltaic-Diesel-Battery (PVDB) hybrid system. The proposed scheme is modeled and simulated using MATLAB-SIMULINK and FUZZY toolbox. The FLC is designed, to work simultaneously with the commonly used ON-OFF controller,(More)
This paper gives a complete computer simulation program of a single phase grid connected PV system using Matlab/Simulink and SimPowerSystem tool in order to monitor the performance of each unit of the system during a selected day in the year representing a sunny day and another cloudy day using the hourly data of load demand, solar radiation and temperature(More)
A new modified configuration for the stand-alone photovoltaic (PV) system to electrify a remote area household load in Egypt is presented. The modeling, simulation, and operational control strategy for the system is developed. The developed control aims to optimize the energy flow within the system, such that the load is satisfied independent on the(More)
This paper explain the creation of a Matlab-Simulink model for a tidal current turbine system through the modeling of the source, the rotor, drive train and the generator. The aim of the simulation model is to illustrate how the tidal current energy system works and how to make use of it in power generation. Harnessing tidal currents power done through(More)
This paper, we employ the technique of degenerate kernel method by using the linear polynomial operator which plays an important role in study of numerical technique can be used to obtain the results of that problem. A numerical example is reported at the end of this paper to illustrate our technique. 2004 Elsevier Inc. All rights reserved.
