Paper In modern trend renewable energy sources has taken vast place in power generation. out of all renewable energy sources solar power generation source has high efficiency . in our paper we have using a converter which step up the power generation through photo voltaic cell. Coupled inductor topology not step up input but also provides uninterrupted power supply to load. This type of system is used in island applications. Voltage developed by photo voltaic cell is 15v which is step up to 220V using our proposed converter with power of 100W, this converter provide output which is fifteen times of input. This converter is transformer less and has negligence losses therefore it is DC-DC converter used for DC applications and for Ac applications by connecting an inverter to it.

Autonomous Power Systems

The urgency of developing renewable power generation in Russia is associated with the presence of a large number of regions with a low degree of electrification. More than two-thirds of the territory of Russia is located in the area of decentralized power supply, where the main source of energy is imported diesel fuel or associated gas from local fields. At present, one of the directions for the development of renewable power generation in Russia is the implementation of a hybrid power supply system for autonomous power systems of remote regions. However, along with the possibility of using renewable energy sources, it is important for such regions to generate heat from co-generation of diesel power plants, since there is an urgent problem of heat supply for remote regions, especially located in the Far North of Russia. This article presents an analysis of the influence of using renewable energy sources in autonomous power systems on co-generation of diesel power plants.

The key to sustainable economic development is having adequate electricity to power homes and industrial machines. However, electric power supply in majority of developing countries is grossly inadequate. To improve on the power generation different renewable energy sources have been explored. One of the sources of renewable energy is the application of speed breaker system to convert kinetic energy of moving vehicles into electricity using various mechanisms. The purpose of this paper is to develop a methodology for determining the most appropriate mechanism of speed breaker system for effective power generation. The proposed approach aggregated the AHP and the WASPAS methods. The efficacy of the methodology is illustrated with a numerical example. From the analysis, the optimum speed breaker mechanism for power generation is the roller mechanism. A sensitivity analysis was also carried out to determine the effect of one of the parameters of the proposed method on the performance of the different mechanisms. The result of the sensitivity analysis showed that the optimum solution remained unchanged.

Utility Grid

The rapid day-by-day growth of urbanization significantly increases the burden on utility grid that leads to frequent grid failures. So, Renewable Energy Sources (RES) based local power supply systems, called microgrids, are evolved to augment the utility grid supply. However, these microgrids possess uncertain power generation capacity due to the dependency on variable and uncertain environmental conditions. Thus, the grid failures continued due to unreliable operation of the microgrids. So, as a solution to enhance the reliability of microgrids, this paper suggests an integration of multiple microgrids in an urban locality, which are built by different RES and form a local integrated grid, called “minigrid”. This is further motivated by the present scenario of urban buildings, where most of the cases, the heterogeneous load natured buildings are grouped together in an urban neighborhood, thereby, facilitating resource sharing. This collective operation of multiple microgrids share the generators across all of their loads, thereby manages the power requirement in the locality itself instead of depending on the utility grid. With this view, this paper discusses the development of urban community minigrid, which is formed by integrating different categories of buildings, where each building is associated with its microgrid. This proposed minigrid scheme enhances the power supply reliability by enabling power-sharing among the buildings; as a consequence, it reduces the burden on utility grid. Further, this minigrid enables power import or export to the utility grid during deficit or excess local power generation conditions.

Agricultural Residue

The European Union has set targets for renewable energy utilization. Poland is a member of the EU, and its authorities support an increase in renewable energy use. The background of this study is based on the role of renewable energy sources in improving energy security and mitigation of climate change. Agricultural waste is of a significant role in bioenergy. However, there is a lack of integrated methodology for the measurement of its potential. The possibility of developing an integrated evaluation methodology for renewable energy potential and its spatial distribution was assumed as the hypothesis. The novelty of this study is the integration of two renewable energy sources: crop residues and animal husbandry waste (for biogas). To determine agricultural waste energy potential, we took into account straw requirements for stock-raising and soil conservation. The total energy potential of agricultural waste was estimated at 279.94 PJ. It can cover up to 15% of national power generation. The spatial distribution of the agricultural residue energy potential was examined. This information can be used to predict appropriate locations for biomass-based power generation facilities. The potential reduction in carbon dioxide emissions ranges from 25.7 to 33.5 Mt per year.

This critical review report highlights the enormous potentiality and availability of renewable energy sources in the Gulf region. The earth suffers from extreme air pollution, climate changes, and extreme problems due to the enormous usage of underground carbon resources applications materialized in industrial, transport, and domestic sectors. The countries under Gulf Cooperation Council, i.e., Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates, mainly explore those underground carbon resources for crude oil extraction and natural gas production. As a nonrenewable resource, these are bound to be exhausted in the near future. Hence, this review discusses the importance and feasibility of renewable sources in the Gulf region to persuade the scientific community to launch and explore renewable sources to obtain the maximum benefit in electric power generation. In most parts of the Gulf region, solar and wind energy sources are abundantly available. However, attempts to harness those resources are very limited. Furthermore, in this review report, innovative areas of advanced research (such as bioenergy, biomass) were proposed for the Gulf region to extract those resources at a higher magnitude to generate surplus power generation. Overall, this report clearly depicts the current scenario, current power demand, currently installed capacities, and the future strategies of power production from renewable power sources (viz., solar, wind, tidal, biomass, and bioenergy) in each and every part of the Gulf region.
