Wind Energy Potential

The significant offshore wind energy potential of Oregon faces several challenges, including a power grid which was not developed for the purpose of transmitting energy from the ocean. The grid impacts of the energy resource are considered through the lenses of (i) resource complementarity with Variable Renewable Energy resources; (ii) correlations with load profiles from the four balancing authorities with territory in Oregon; and (iii) spatial value to regional and coastal grids as represented through a production cost model of the Western Interconnection. The capacity implications of the interactions between offshore wind and the historical east-to-west power flows of the region are discussed. The existing system is shown to accommodate more than two gigawatts of offshore wind interconnections with minimal curtailment. Through three gigawatts of interconnection, transmission flows indicate a reduction of coastal and statewide energy imports as well as minimal statewide energy exports.

Most of the industries including the oil sector are looking forward towards the renewable energy resources with proper energy management system (EMS) as it is the need of time. For this purpose, solar and wind energy are the renewable energy resources, which are obtained from natural resources and produce clean and environment -friendly electrical energy and can be used for oil depots. The proper utilization of solar and wind energy from natural resource may result in economical and cost-effective EMS. In the proposed research work, an effective energy management demonstration is delivered to ensure the ceaseless flexibility of power. Furthermore, reduction of production per unit cost to the oil sector industry by utilizing multiple objectives streamlining. In the proposed oil depot, connected loads are divided into Shiftable and Non-Shiftable loads and then apply Branch and Bound Algorithm (BnB) with binary integer linear programming (BILP). By using the BnB technique, selected shiftable loads are shifted to the low cost energy resource automatically and resultantly, we get the low price unit cost and continuous power supply. Simulation results for the above-mentioned research work are performed on MATLAB. The proposed technique helps to reduce the power stack shedding issue as well.

This paper addressed assessing feasibility of hybrid use of ocean renewable energy, such as wave and wind energy around Japanese coast. At first, wave and wind energy theoretical potentials were calculated and, in the second step, correlation coefficient between wave and wind energy was computed around Japanese coast. Sea area suitable for hybrid use of ocean renewable energy resources is supposed to have high potential for some types of energy resources. Furthermore, correlation of power generation between wave and wind energy resources should be low because one energy resource needs to complement another one for stabilizing power generation. Based on the assumptions, feasibility of wind and wave energy was evaluated on some sea areas where R&D project are ongoing.

Turbine Construction

Generally, wind energy sources in Indonesia's coastal areas is one of the potential sources of renewable energy (renewable energy resources) which are abundant, environmentally friendly and renewable. Savonius wind turbines can produce relatively high torque even at low wind speeds. Because it is very well developed to produce electrical energy. To get a large electric power, a large turbine construction is also needed which also certainly requires a large cost. For this reason, it is necessary to develop the dimensions of this wind turbine construction which is known as aspect ratio (Ar). The Ar that has been researched is the blade section, and other values. While the arch depth or the length of the blade arc in U -type is still likely to be researched. Therefore, it is necessary to do research on the U-type blade arc to get greater power than before. In addition to the experimental method with a prototype of the U type Savonius wind turbine with a number of 2 blades, a software-based simulation method will be carried out to analyze the air flow on the wind turbine blade. Parameters varied only with the aspect ratio of the arc length and blade cross section width, other parameters follow the previous research. This analysis will be a comparative data with experimental methods. The expected simulation results obtain the best aspect ratio (Ar) blade in capturing wind energy.

Joint Evaluation

In this study, a joint evaluation of the wind and wave energy over the Black Sea basin is performed for a 20-year time interval. The importance of such a study is enhanced by the fact that the potential of the wave energy cannot be considered high compared to the large oceans, while the wind conditions over the Black Sea can be considered significant in various areas. The wind fields from the U.S. National Centers for Environmental Prediction were used for wind energy estimation. A high resolution wave hindcast database, as resulted from the simulations performed with the Simulating WAves Nearshore model, is used for a detailed analysis of the wave energy potential in the basin of the Black Sea. The reliability of the wave simulation results was increased by means of some data assimilation methodologies. The variability and complementarity of these renewable energy resources was investigated. The analysis showed that there exist some suitable areas for combined wind-wave exploitation.

Advantages And Disadvantages

The non-renewable energy resources are limited and depleting gradually. As such, energy security has attained the greatest amount of attention globally than ever before. In the meantime, energy crises are already affecting the developing countries such as Pakistan, even though one-third of the population of the country is not even not connected to the national electricity grid. The population with access to on-grid electricity is enduring load shedding of more than 12 h a day. This situation is alarming and require immediate attention is required so as to add alternative energy resources to the country, which has long been relying on imported fuels. It is, therefore, high time that the abundant potential in the renewable energy resources of Pakistan such as solar, wind, and biomass are harnessed. These renewable energy resources are economical and environmentally friendly, and thus considered as sustainable, and the utilization of these in meeting energy demands can help to conserve conventional resources early diminishing. This paper provides a detailed description of the energy consumption and load-shedding scenario in Pakistan thereby focusing specifically Sindh and Baluchistan provinces. Since, wind energy is considered one of the cost-effective renewable resources, six potential sites in these two provinces are considered in this study. These sites lie within 250 km of the southeastern and 800 km of the southwestern regions of Pakistan. One-year wind speed data have been reported for variable heights of these proposed sites which represent to have an annual average wind speed of 6.63 m/s and 5.33 m/s respectively. The power generation data for these location of two provinces is 7.653 GWh, and 5.456 GWh per annum respectively. This study also elaborates on the advantages and disadvantages of harvesting and installing the wind energy and provides a technical proposal for the generation of electricity from the wind in the selected remote zones which are off the national grid. The findings of this paper will help concerned government departments to devise appropriate policies and attract investment in the wind energy sector to eradicate the on-going electricity crisis.
