In the field of photovoltaic (PV) plants and energy conversion from renewable sources, a large part of the technical literature is more devoted to practical aspects (new solar cells, electrically driven PV panels, safety, reduction of parasitic currents, etc.) than to theoretical investigations. Despite this tendency, this paper presents a mathematical analysis of a medium scale photovoltaic po...

This paper considers selection of the suitable simulation model for solar panels [1]. Two models for silicon polycrystalline photovoltaic solar cells [2], [3] were analysed. The selection is made by comparing the Power vs. Voltage and Current vs. Voltage curves obtained from the simulation to those obtained experimentally. The goal is to identify if a simulation model gives correct information ...

The output power of photovoltaic (PV) module varies with module temperature, solar isolation and 1oad changes etc. In order to control the output power of single-phase gridconnected PV system according to the output power PV arrays, this paper presents a single-phase photovoltaic system that provides grid voltage support and Compensation of harmonic distortion at the point of common coupling (P...

Due to ready availability of resources, there is a vast spike in the growth of sustainable power sources. Among them solar photovoltaic (PV) world power technique is presently careful, being an of great magnitude substitute influence supplier, for the reason that of the set availability of eminent able PV panels with the aim of eliminate the depressing environmental aspects. Low voltage PV syst...

INTRODUCTION Freely accessible online tests for the diagnosis of Alzheimer's disease (AD) are widely available. The objective of this study was to evaluate these tests along three dimensions as follows: (1) scientific validity; (2) human-computer interaction (HCI) features; and (3) ethics features. METHODS A sample of 16 online tests was identified through a keyword search. A rating grid for ...

Solar energy has been subject of great development in the past years, which led to the concept of Solar Roads: photovoltaic panels along the highways and roads. SmartSolarGrid is the merge of Solar Roads with Smart Grids, a new electrical distribution grid with improved efficiency and control. The goal of this work is to develop a software tool that further improves the efficiency of the electr...

This paper presents the development of a decision support system (DSS) for a low-voltage grid with renewable energy sources (photovoltaic panels and wind turbine) which aims at achieving energy balance in a pilot microgrid with less energy consumed from the network. The DSS is based on a procedural decision algorithm that is applied on a pilot microgrid, with energy produced from renewable ener...

In the paper we aim to describe the project developing the Migrating Desktop infrastructure for the mobile users in a simple way. We also focus on the development testbed, which is prepared for the testing purposes of the runtime environment. This functionality refers to the work environment of the users, which change their location very often. The mobility term refers to the users, which use t...

This paper deals with free vibration analysis of thick Laminated curved panels with finite length, based on the three-dimensional elasticity theory. Because of using two-dimensional generalized differential quadrature method, the present approach makes possible vibration analysis of cylindrical panels with two opposite axial edges simply supported and arbitrary boundary conditions including Fre...
