Photovoltaic Energy

The photovoltaic energy can become competitive by the conjugate effort of the researchers and manufacturers. Increasing the amount of electricity supplied by photovoltaic panels is a challenge. The paper briefly presents some methods which can lead to achieving this goal. A simple method to increase the quantity of the electrical energy delivered by the photovoltaic panels is also presented in this paper alongside the experimental setup and the software created in LabVIEW for monitoring the output of the panels.

The photovoltaic systems are often employed into micro-grids; Micro-grids are small power grids designed to provide a reliable and better power supply to a small number of consumers using renewable energy sources. This paper deals with DC micro-grids and present a new system of monitoring and sharing electricity between homes equipped with photovoltaic panels (PV) in the goal to reduce the electrical energy waste. The system is based on dynamic sharing of photovoltaic blocks through homes in stand-alone areas, using an arduino board for controlling the switching matrix. The LABVIEW program is used to further process and display collected data from the system in the PC screen. A small-scale prototype has been developed in a laboratory to proof the concept. This prototype demonstrates the feasibility and functionality of the system.

Abstract The paper analyses the way of design of photovoltaic systems. The objective of this paper is to study the production capacity of electrical energy and the way it is influenced by real time conditions. In order to realize some energetic models that could be implemented on a large scale and used as a model of good practice we used photovoltaic systems of 3 dimensions: 60 PV panels, 100 PV panels and 160 PV panels respectively. The present study considered the climate conditions of the city of Cluj-Napoca for 12 months. It considered the consumption profile (hourly consumption) and the period of the year (summer, winter, etc.) for 3 typical buildings. We used Matlab/Simulink software for simulations. The result is an estimation of the production of electrical energy for renewable sources and the reduction of GreenHouse Gases (GHG). The aim is to reduce both GHG and the energy consumption from conventional sources.

The Impact

This study aims at providing the influence of the endowment on solar energy. And its reflection on the scientific university life. Also it aims at supporting the university education in Palestine by supporting new ideas to support the scientific research's by clarifying the legal texts, according to university situations to reduce deficit value in Palestinian universities. The electrical energy is considered the main columns of the environmental and civilization progress. As it's mainly connected to the instruments and equipment that make life easier. These instruments burn fuel that leads to harmful and dangerous effects on environment. During scientific research'. scientists found out that they can convert solar energy into Photovoltaic energy that doesn't need to burn fuel to be generated. This saves money as well as building new cultures to help in modernising the world. The abstract reach's to great likeness of the use of the endowment to serve the generated solar system. It's mainly a good application for the Islamic legal services on a solid ground. And it's related to environment protection and to saving money. So the legal endowment is able to solve problems of the continuous increasing cost of traditional power components.

AbstractA photovoltaic (PV) module is an equipment that converts solar energy to electrical energy. A mathematical model should be presented to show the behavior of this device. The well-known single-diode and double-diode models are utilized to demonstrate the electrical behavior of the PV module. “Matlab/Simulink” is used to model and simulate the PV models because it is considered a major software for modeling, analyzing, and solving dynamic system real problems. In this work, a new modeling method based on the “Multiplexer and Functions blocks” in the "Matlab/Simulink Library" is presented. The mathematical analysis of single and double diodes is conducted on the basis of their equivalent circuits with simple modification. The corresponding equations are built in Matlab by using the proposed method. The unknown internal parameters of the PV panel circuit are extracted by using the PV array tool in Simulink, which is a simple method to obtain the PV parameters at certain weather conditions. Double-diode model results are compared with the single-diode model under various irradiances and temperatures to verify the performance and accuracy of the proposed method. The proposed method shows good agreement in terms of the I–V and P–V characteristics. A monocrystalline NST-120 W PV module is used to validate the proposed method. This module is connected to a variable load and tested for one summer day. The experimental voltage, current, and power are obtained under various irradiances and temperatures, and the I–V and P–V characteristics are obtained.

To pursue VNIIEF–VNIITF joint investigations, this paper briefly describes the experimental setup and provides numerical 3D-computation results (LEGAK-3D technique) on special features in the convergence dynamics of steel shells under their quasi-spherical explosive loading in the system with the 40-mm outer radius of the explosive layer. The computation results were compared with the data experimentally registered for shells of the 30KhGSA steel, both as-received and quenched to HRC 35…40, and the austenitic 12Kh18N10T stainless steel. The comparison was also made with laser-interferometry results obtained directly under explosive loading, as well as with gamma-tomography and scanning electron microscopy investigations of the recovered shells.

Simple Method

An energy-efficient and simple method of testing electric motors in a dynamic mode is considered. When testing an electrical machine, the rotor is driven into a reciprocating rotary motion. The source of power of the power converter, which controls the electric machine, is a supercapacitor. When the electric machine is accelerated, electric energy is consumed from the supercapacitor, when the machine brakes the kinetic energy of the moving masses is converted into electrical energy, which accumulates in the supercapacitor. The energy loss during the operation of the electromechanical system in the dynamic mode is compensated by recharging the supercapacitor using a controlled rectifier connected to the power supply network.
