The utilization of renewable energy sources in electric power systems is increasing quickly because of public apprehensions for unpleasant environmental impacts and increase in the energy costs involved with the use of conventional energy sources. Despite the application of these energy sources can considerably diminish the system fuel costs, they can also have significant influence on the syst...

We investigate the one-parameter Calabi-Yau models and identify families of D5-branes which are associated to lines embedded in these manifolds. The moduli spaces are given by sets of Riemann curves, which form a web whose intersection points are described by permutation branes. We arrive at a geometric interpretation for bulk-boundary correlators as holomorphic differentials on the moduli spac...

This paper presents the optimal design and simulation of a grid-connected Photovoltaic (PV) system to supply electric power to meet the energy demand by Electrical Department in University of Tripoli Libya. Solar radiation is the key factor determining electricity produced by photovoltaic (PV) systems. This paper is designed to develop a novel method to calculate the solar photovoltaic generati...

Photovoltaic energy is one of the fastest growing renewable energy sources in the worldand as the issue of energy security is becoming more and more important it could be a promising option. But as photovoltaic energy is becoming widespread and penetration level of photovoltaic power plants increase, issues rise in distribution networks.In this paper a power control scheme for a high penetratio...

Global warming is a direct consequence of consumption of fossil fuels which emit greenhouse gasses as they produce energy. Solar energy is the most available energy throughout the world in which regardless of capital investment is free and most importantly clean and emission free and could be a solution for global warming along with other renewable sources of energy. But as photovoltaic energy ...

developing electrical energy is one of the basic needs for development, so equipping the rural regions and villiages is one of the main responisiblities of thirdworld countries. in this study, we used economic evaluation indexes to compare electrification to baghtaj village by power grid expansion and application of solar photovoltaic systems. economic evaluation indexes suggests that in the ab...

using photovoltaic systems is gradually expanded by increasing energy demand. abundance and availability of this energy, has turned to one of the most important sources of renewable energy. unfortunately, photovoltaic systems have two big problems: first, those have very low energy conversion efficiency (in act between 12 and 42 percent under certain circumstances). second, the power produced b...

Abstract Photovoltaic (PV) systems can be used to generate electricity due the potential for solar energy in Iran. Applying floating photovoltaic (FPV) is a new approach utilizing PV water. Most of Iran’s consumption supplied from fossil fuels, especially oil and gas. In recent years, Iran has faced environmental problems air pollution. Electricity generation using fuels led increased According...

Stand alone renewable energy based on photovoltaic systems accompanied with battery storage system are beginning to play an important role over the world to supply power to remote areas. The objective of the study reported in this paper is to elaborate and design a bond graphs model for sizing standalone domestic solar photovoltaic electricity systems and simulating the performance of the syste...
