research topics dealing with the application of the markal model have been quite common in the last 20+ years. every new paper has added new insight into the potential of using such a model for a variety of purposes. not only global but also local applications have shown both limits and benefits when dealing with manifold energy-environmental-resources optimal management. the aim of this wo...

This study evaluated the energy saving potential of renewable generation systems based on integrated solar in an urban environment. The city concept was implemented using photovoltaic (PV) and thermal systems. As a case study, Sejong national pilot smart South Korea selected to evaluate penetration rate. For evaluating proposed systems, electrical loads were estimated field measurement data. Th...

The rapid industrialization and growth of world’s human population have resulted in the unprecedented increase in the demand for energy and in particular electricity. Depletion of fossil fuels and impacts of global warming caused widespread attention using renewable energy sources, especially wind and solar energies. Energy security under varying weather conditions and the corresponding system ...

Considerable efforts have been made to reduce the energy consumption of buildings due to the energy crisis, and, the Korean government has supported the use of renewable energy through various grants. Among the possible renewable energy sources, geothermal energy can be used regardless of the outside weather. Therefore, energy consumption can be reduced considerably in summer and winter. Despit...

Recently, environmental issues have been the focus of much of the world’s attention. This has stimulated a response in many countries, which has led to a closer examination of energy conservation strategies for conventional fossil fuels. One way of reducing building energy consumption is to design buildings, which are more economical in their use of energy for: heating, lighting, cooling, venti...

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...

Recent year’s renewable energy sources plays important role in power generation system. Due to intermittent nature of renewable sources such as wind and solar, the energy storage systems (ESS) are required in renewable power generating systems. This paper deals with power management of the ESS based on hydrogen storage (electrolyzer, hydrogen tank, fuel cell) and battery integrated in hybrid re...

today, using new and renewable energy sources to replace fossil fuels is greatly expanded. the solar cells are devices that convert solar energy to electrical energy. solar cells based on organic materials, especially proteins, are one of these solar cells. for example, bacteriorhodopsin (br) which is one of the membrane proteins in halobacterium salinarum could be used in solar cells and parti...

Environmental concerns about using fossil fuels, and their resource constraints along with energy security concerns, have spurred great interest in generating electrical energy from renewable sources. The variable and stochastic nature of renewable sources, however, makes solar and wind power diffi cult to manage, especially at high levels of penetration. Electrical energy storage (EES) is nece...

This study deals with system integration and power management of a stand-alone renewable energy (RE) hybrid system, which is in its final stage of construction in Lambton College (Sarnia, Ontario, Canada). The system consists of five main components: photovoltaic (PV), wind turbine, electrolyzer, hydrogen storage tanks and fuel cell. The model for each process component was developed and the hy...
