The regulations for environmental issues on the use of fossil energy and the upsurge of the power demand due to the improving standard of living worldwide increasingly require the development of renewable energy sources. In particular, developing countries suffer from severe lack of energy because they do not have technical ability for large-capacity generation facilities, such as thermal or nuclear power generation plants, and financial capacity to procure the resources. Therefore, most countries are trying to develop the renewable energy sources, especially the solar generation facilities. In the solar power generation system, the structural stability of the support unit that supports the large-area solar panel is essential to ensure the high generation efficiency and the long life of the system. According to the international standards and industry practice, the solar power system must be stable against the 120 km/h wind and its life must be 20 years or longer. The solar panel for the solar generation system are made by combining ten to several tens of solar modules depending on the scale of the system. This generates a load of at least 250 kg, and if the aerodynamic force due to the strong wind is additionally applied, the severe ground settlement of the support unit on the weak ground may damage the system. In this study, the structure of the solar power system, which can operate stably in the areas with weak ground, such as Laos and Vietnam, is proposed. Diverse load distributions and structure deformations were calculated via numerical analysis, and the typical ground characteristics of the subject areas were considered to determine the structure that minimizes the settlement.

he current energy crisis has once again taught us, the people of Indonesia, that serious and systematic efforts to develop and implement renewable energy sources to reduce dependence on fuel must be carried out immediately. The use of renewable and environmentally friendly energy sources, especially those that can reduce the various adverse effects caused by the use of fossil fuels. The urge to leave petroleum as a source of national energy supply is currently being rolled out by various parties, including themselves. These steps are needed to get Indonesia out of the sustainable energy crisis. To optimize the need to combine two generators, namely PLTS with PLTB. The purpose of this study was to determine the combination of a power generation system produced by a vertical wind power plant with solar power with a hybrid system which is expected to optimize the power generation system between the two plants.

There are many renewable energy sources in nature today. The most commonly used of these are solar, wave, wind and flow energy. The weakest aspect of these renewable energy sources in nature is that the amount of energy produced depends on the nature conditions. The power generation capacities of these energy sources depending on the weather conditions in order to more stable them are necessary to combine. By combining more than one renewable energy source, a hybrid power generation system is created. Hybrid energy storage units are added to this hybrid power generation system to ensure persistence of energy. In this study, sea flow energy and offshore wind energy are combined and a hybrid power generation system has been created. In addition, a hybrid energy storage unit consisting of a battery and ultracapacitor has been created in order to ensure the persistence of the energy produced. All two hybrid units were simulated using MATLAB/Simulink program. By integrating these systems with each other, their dynamic behaviors were investigated under possible working conditions. The results of the simulation show that the hybrid energy storage unit supports the wind and sea flow energy.

Promising Source

The rising demands for a sustainable energy system have stimulated global interests in renewable energy sources. Wind is the fastest growing and promising source of renewable power generation globally. The inclusion of wind power into the electric grid can severely impact the monetary cost, stability and quality of the grid network due to the erratic nature of wind. Power electronics technology can enable optimum performance of the wind power generation system, transferring suitable and applicable energy to the electricity grid. Power electronics can be used for smooth transfer of wind energy to electricity grid but the technology for wind turbines is influenced by the type of generator employed, the energy demand and the grid requirements. This paper investigates the constraints and standards of wind energy conversion technology and the enabling power electronic technology for integration to electricity grid.

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.
