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,...

Renewable energy provides twenty percent of electricity generation worldwide. Hydroelectric power is the cheapest way to generate electricity today. It is a renewable source of energy and provides almost one-fifth of electricity in the world. Also, it generates electricity using a renewable natural resource and accounting for six percent of worldwide energy supply or about fifteen percent of th...

The current electricity demand has asserted the mandatory requirement of establishing renewable energy systems. This paper reviews the major contributions on practically establishing the hybrid renewable energy systems. The contributions are investigated for its practical relevance with the growing demand, exploration of various renewable energy resources and performance accomplishment. The per...

abstract intensive and inefficient use of energy leads to degradation of natural resources and environmental problems. this study evaluated the relationship between the energy of consumed inputs and yield of tomato, cucumber and melon using the cobb–douglas production function. the data were collected from 90 farmers in firoozabad using a questionnaire. the farmers were chosen by simple random ...

Hybrid utilization of renewable energy is one of effective method which can solve the problem that unstable of renewable energy so as not to substitute traditional fossil energy. As the typical renewable energy, solar energy and wind energy are in the van of renewable energy utilization. With the large scale utilization of solar and wind energy in the world, constructing large scale solar power...

Recent efforts to site renewable energy projects have provoked as much, if not more, opposition than conventional energy projects. Because renewable energy resources are often located in sensitive and isolated environments, such as pristine mountain ranges or coastal waters, siting these facilities is especially difficult. Moreover, the viability of different renewable energy projects depends n...

Abstract Bit by bit the energy demand is extending and thusly necessities for a sustainable source that won’t hurt environment are of prime importance. A couple projections express 2050 solicitation will essentially increment. Anyway larger piece satisfied oil subordinates yet use harmless to ecosystem power structures could help in giving demands. As we as whole realize which either created cl...

Hydrogen is readily obtained from renewable and non-renewable resources via water splitting by using thermal, electrical, photonic and biochemical energy. The major hydrogen production is generated from thermal energy through steam reforming/gasification of fossil fuel. As the commonly used non-renewable resources will be depleted in the long run, there is great demand to utilize renewable ener...

China’s 2020 Renewable Portfolio Standards (RPS) target has been published by the government in early 2016. In the present study, in order to find its implementation pathways and estimate the key impacts of PRS target out to 2030, a multi-region power market model is proposed to investigate different RPS policy scenarios. Results show that RPS policy can promote the development of renewable ene...
