Iran has several potential for using renewable energies, so use them could significantly contribute to energy supply. The purpose of this paper is to identify the potential of the country and select the appropriate DG technologies with consideration the potential and primary energy resources in the regions. In this context, hybrid energy systems proportionate with the potential of different reg...

This paper addresses the dual questions: What is the appropriate storage size and its related properties for matching very large photovoltaic plants to the grid; and what are the available technologies for achieving this end. For this purpose a ‘‘Usefulness Index’’ is defined, which, for any grid flexibility, leads to a PV-storage combination that allows high grid-penetration without storage be...

Glossary Convention on biological diversity The Convention was first enacted in June 1992, has been signed by many countries, and its objectives are the conservation of biological diversity, the sustainable use of its components and the fair and equitable sharing of the benefits arising out of the utilization of genetic resources, including by appropriate access to genetic resources and by appr...

the share of dc-based renewable energy resources (rers) and electricity storage systems are increasing due to developments of smart grid technologies. moreover, the share of dc-based load has rapid growth due to significant developments of power electronic technologies. therefore, a more flexible power system is required for efficient integration of emerging loads and generators. in this paper,...

Jackson et al describe a complex timing cycle interaction in a patient with a dual-chamber implantable cardioverter– defibrillator. The intracardiac electrograms provided along with their description of an algorithmic approach to differential diagnosis is ripe with teaching points typical of the bedside rounds of yesteryear. Complex cases require not only meticulous logical analysis of the avai...
