Assessing the Techno-enviro-economic Viability of Wind Farms to Address Electricity Shortages and Foster Sustainability in Palestine

This study critically examines the feasibility of wind turbines in addressing electricity shortages in the coastal region of Palestine. Assessing technical, economic, and environmental aspects offers vital insights for sustainable energy solutions. Hence, 10 turbines with different rated powers were selected to determine the optimal and economically viable solution. Wind velocities were assessed at altitudes of 10, 65, and 80 meters. Various performance indicators such as wind power density, capacity factor (Cf), anticipated energy yield, cost of wind-generated electricity, benefit-cost ratio (BCR), and simple payback period were examined. The findings indicate that the Siemens SWT-2.3-93 turbine yields an annual energy production of 3910.3 MWh. The Lagerwey-LW58/750 turbine boasts the highest capacity factor at 20.5% making it the most cost-effective option with generation costs of $0.0604/kWh to $0.0825/kWh. It exhibited the highest benefit-cost ratio, ranging from 1.287 to 1.758, and payback period of 6.33 years. Consequently, the Lagerwey-LW58/750 turbine emerges as the optimal choice for implementing the wind power plant project in Palestine's coastal region. The use of wind turbines to generate electricity leads to 3323.75 ton/year of emissions reduction. This research provides crucial insights for decision-makers aiming to tackle electricity shortages and enhance environmental sustainability in Palestine’s energy sector.

Computational Investigations of Small Deploying Tabs and Flaps for Aerodynamic Load Control

The cost of wind-generated electricity can be reduced by mitigating fatigue loads acting on the blades of wind turbine rotors. One way to accomplish this is with active aerodynamic load control devices that supplement the load control obtainable with current full-span pitch control. Techniques to actively mitigate blade loads that are being considered include individual blade pitch control, trailing-edge flaps, and other much smaller trailing-edge devices such as microtabs and microflaps. The focus of this paper is on the latter aerodynamic devices, their time-dependent effect on sectional lift, drag, and pitching moment, and their effectiveness in mitigating high frequency loads on the wind turbine. Although these small devices show promise for this application, significant challenges must be overcome before they can be demonstrated to be a viable, cost-effective technology.

Wind energy technology—the state of the art

Wind energy technology has developed extremely rapidly, and many commercial wind turbines now on the market have capacity ratings of 1MW or more. Energy productivity per unit of rotor area has steadily improved. Turbine prices have decreased per unit capacity, so the cost of wind-generated electricity has fallen steadily. This paper examines the underlying reasons behind the changes in design, explores the economics of wind and discusses integration issues. It looks, finally, to further developments, including offshore wind energy.

Wind Energy Technology, Status Review

Wind energy technology has developed extremely rapidly, and many commercial wind turbines now on the market have capacity ratings of one megawatt or more. Energy productivity per unit of rotor area has steadily improved. Turbine prices have decreased per unit capacity, so the cost of wind-generated electricity has fallen steadily. This paper examines design concepts, applications and economics, and looks to further developments, including offshore wind energy.

Advanced Wind Turbine Design

Garrad Hassan have a project in progress funded by the U.K. Department of Trade & Industry (DTI) to assess the prospects and Cost benefits of advanced wind turbine design. In the course of this work, a new concept, the coned rotor design, has been developed. This enables a wind turbine system to operate in effect with variable rotor diameter augmenting energy capture in light winds and shedding loads in storm conditions. Comparisons with conventional design suggest that a major benefit in reduced cost of wind-generated electricity may be possible.
