The use of renewable energy sources is increasingly being pursued as a supplemental and an alternative to traditional energy generation. Several distributed energy systems are expected to a have a significant impact on the energy industry in the near future. As such, the renewable energy systems are presently undergoing a rapid change in technology and use. Such a feature is enabled clearly by power electronics. Both the solar-thermal and photovoltaic (PV) technologies have an almost exponential growth in installed capacity and applications. Both of them contribute to the overall grid control and power electronics research and advancement. Among the renewable energy systems, photovoltaic (PV) systems are the ones that make use of an extended scale of the advanced power electronics technologies. The specification of a power electronics interface is subject to the requirements related not only to the renewable energy source itself but also to its effects on the operations of the systems on which it is connected, especially the ones where these intermittent energy sources constitute a significant part of the total system capacity. Power electronics can also play a significant role in enhancing the performance and efficiency of PV systems. Furthermore, the use of appropriate power electronics enables solar generated electricity to be integrated into power grid. Aside from improving the quality of solar panels themselves, power electronics can provide another means of improving energy efficiency in PV and solar-thermal energy systems.

Technical Requirements

Airports are key components of the global transportation system and are the subject of continuous sustainability improvements. Promoting clean energy sources and energy-efficient practices can help attain major sustainability goals at airports around the world. Although small airports are greater in number, most of the “sustainability” attention has been given to large airports. Small airports are typically located in rural areas, making them excellent candidates for renewable energy. This paper focuses on the planning and selection of renewable energy systems as a strategic method to reduce energy use and increase electric power reliability at small-scale airport facilities. The target system may use a combination of renewable energy sources to produce electrical power for the on-site facilities. The framework details include methods of energy collection, power production, and energy storage that are environmentally sound. A small airport serving a dual role as a flight training facility was used as case study. In the case study, systems engineering methodology was adapted to the small airport/ renewable energy domain in order to effectively identify stakeholders and elicit user requirements. These, coupled with industrial standards, relevant government regulations, and a priori constraints, are used to derive the initial requirements that serve as the basis for a preliminary design. The proposed framework also contains provisions for an on-site assessment of existing airport energy needs, sources, providers, and location-specific assets and challenges.

Distributed Energy System

Abstract Small-scale renewable energy systems in the context of the development of distributed generation, are discussed for the case of Poland. A distributed energy system is efficient, reliable and environmentally friendly, and is one of the most recent trends in the development of the energy sector in Poland. One of the important dimensions of this process is the creation of micro- and small-power producers based on renewable, locally-available energy sources. It is clear that the development of small-scale renewable energy producers takes place in two ways. One of these is through small hydropower plants, which are the aftermath of hydropower development in areas traditionally associated with water use for energy purposes (northern and western Poland). The second is through other renewable energy sources, mainly biogas and solar energy and located primarily in southern Poland, in highly urbanized areas (e.g. Śląskie Voivodship). In conclusion, the development of small-scale renewable energy systems in Poland is regarded as a good option with respect to sustainable development.

The Relationship

This paper tries to offer lessons about the very long run aspects of a future economy reliant predominantly on renewable energy sources. The evidence is based on past economies and civilizations and their experiences of economic expansion driven by renewable energy resources. The paper proposes that economies around the world, since antiquity, have managed to survive, and even develop and grow driven by renewable energy sources. Successful long run economic growth depended on sound management of demand, supply and trade of wood fuel. Where governments failed to develop appropriate policies, growth and development was severely constrained. Despite the uncertainty about the future, this paper proposes that researchers start to consider the nature of long run economic growth and appropriate policies within renewable energy systems.

Hybrid Renewable Energy

The Ukrainian energy sector is one of the most inflexible energy sectors in the world as a result of the almost complete depreciation of the equipment of the main sources of power supply: nuclear, thermal, and hydropower. In connection with existing problems, there is a need to develop and use new energy-saving technologies based on renewable energy sources. In this proposed research, a regression model of renewable energy growth in the energy sector of Ukraine was developed. The studied literature reveals that the independent use of individual functioning elements of renewable energy sources function as the primary power source that is not an optimal solution for stable energy supply. This study proposes the use of hybrid renewable energy systems, namely a combination of two or more renewable energy sources that will help each other to achieve higher energy efficiency, accelerate the growth of renewable energy in the share of the Ukrainian energy sector and/or improve functioning with battery energy storages. Moreover, the use of hybrid renewable energy systems in Ukraine will reduce the human impact on the environment, realize the potential of local renewable energy resources and also increase the share of electricity generation from renewable energy sources. Therefore, mechanisms for managing state regulation of stimulating the development of hybrid renewable energy systems have been developed.

Renewable energy sources such as solar, wind and geothermal are proposed as an alternative to fossil fuels whose excessive use causes global warming. The most popular one of the renewable energy sources is considered as solar energy due to the fact that required energy is provided by the sun entire year around the world. Solar energy systems convert the solar radiation to the useful heat or electricity. In order to achieve better performance in solar thermal systems many studies have been conducted. Some of these studies suggest that heat transfer fluid could be changed with the nanofluids which can be defined as new generation heat transfer fluid. Nanofluids are suspensions of nano-sized particles such as metals, metal-oxides, and Carbon-allotropes (C), in the conventional base-fluids (water, ethylene glycol and oil). Using nanofluid enhances the efficiency and thermal performance of solar systems due to their better thermophysical and optical properties. Recently, C-based nanofluids are getting attention due to their enhanced thermal conductivity and absorptivity at even low concentrations. The results show that C-based nanofluids have a potential to use in solar energy systems: solar collectors, solar stills, photovoltaic/thermal systems.
