Abstract: Solar, wind and other renewable energy sources are becoming an important part of energy supply to the power grid. Integrating a Hybrid Energy Storage Systems (HESS) with renewable energy sources can make these intermittent renewable energy sources more dispatchable. The HESS will play a vital and large role in renewable energy based 3-phase 4-wire grid connected electrical power infra...

Renewable sources are not used to their full potential for electricity generation. Unpredictability of solar and wind power forces renewable generators to bid conservative generation amounts in a dayahead market in order to avoid fees for failure to provide generation. In this paper we propose an approach to increase the use of renewable sources, which allows renewable generators to hedge again...

While various energy-producing technologies have been analyzed to assess the amount of energy returned per unit of energy invested, this type of comprehensive and comparative approach has rarely been applied to other potentially limiting inputs such as water, land, and time. We assess the connection between water and energy production and conduct a comparative analysis for estimating the energy...

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,...

The International Renewable Energy Agency (IRENA) is an intergovernmental organisation dedicated to renewable energy. In accordance with its Statute, IRENA's objective is to "promote the widespread and increased adoption and the sustainable use of all forms of renewable energy". This concerns all forms of energy produced from renewable sources in a sustainable manner and includes bioenergy, geo...

This paper examines the use of policy mechanisms to increase renewable energy consumption within the United States. In order to effectively measure the change of renewable energy consumption, I analyze two initiatives that promote energy consumption from renewable sources and overall increases in energy conservation. Colorado and Washington had approved initiatives in the years 2004 and 2006, r...

China’s population has reached 1.25 billion, ranking No.1 in the world. Along with rapid economic increase during the past 20 years, there is increasing pressure on the energy industry from limited mineral energy resources and regulations for environmental protection regulations. The development and utilization of renewable energy is becoming one important option to realize sustainable developm...

Today due to increasing and evolving of electrical grids, the optimal and profitable energy production is among producers' major concerns. Thus, conventional ways of production and trading energy are being replaced by modern economical procedures. In addition, distributed energy resources (DERs) in form of renewable and conventional resources as well as responsive loads play an important role i...

in the science of operation research and decision theory, selection is the most important process. selection is a process that studies multiple qualitative and quantitative criteria, related to the science of management, which are mostly incompatible with each other. the multi criteria selection of a renewable energy portfolio is one of the main issues considered in multi criteria literature. i...
