Wind Energy Research Paper

The reductions are possible with current technologies and without electrical storage.Wind and solar power increase their share of electricity production as the system grows to encompass large-scale weather patterns.

Specifically, we evaluate three separate cases: neutral stability with low wind shear, high stability with high wind shear, and high stability with nonlinear wind shear.

For most situations, use of the REWS with the wind farm parameterization has marginal impacts on model forecasts.

They generally consider two turbine impacts: elevated drag in the region of the wind turbine rotor disk and increased turbulent kinetic energy production.

The wind farm parameterization available in the Weather Research and Forecasting (WRF) Model calculates this drag and TKE as a function of hub-height wind speed.

A solar PV resource dataset created by combining numerical weather prediction assimilation model variables, satellite data, and high-resolution ground-based measurements is also presented.

The use of wind energy is growing around the world, and its growth is set to continue into the foreseeable future.However, for scenarios with highly nonlinear wind shear, the REWS can significantly affect results. Some energy services and industrial processes — such as long-distance freight transport, air travel, highly reliable electricity, and steel and cement manufacturing — are particularly difficult to provide without adding carbon dioxide (CO2) to the atmosphere.Rapidly growing demand for these services, combined with long lead times for technology development and long lifetimes of energy infrastructure, make decarbonization of these services both essential and urgent.We examine barriers and opportunities associated with these difficult-to-decarbonize services and processes, including possible technological solutions and research and development priorities.A range of existing technologies could meet future demands for these services and processes without net addition of CO2 to the atmosphere, but their use may depend on a combination of cost reductions via research and innovation, as well as coordinated deployment and integration of operations across currently discrete energy industries.However, recent work has suggested that integrating momentum over the entire rotor disk [via a rotor-equivalent wind speed (REWS)] is more appropriate, especially for cases with high wind shear.In this study, we implement the REWS in the WRF wind farm parameterization and evaluate its impacts in an idealized environment, with varying amounts of wind speed shear and wind directional veer.In this paper, we evaluate that study [Jacobson MZ, Delucchi MA, Cameron MA, Frew BA (2015) Proc Natl Acad Sci USA 112(49):15060–15065] and find significant shortcomings in the analysis.In particular, we point out that this work used invalid modeling tools, contained modeling errors, and made implausible and inadequately supported assumptions.Despite the drawbacks to wind turbines, they are more environmentally friendly, and wind is also a renewable resource. Iowa, Minnesota, Colorado and Oregon have also started using wind turbines as a source of power. Other countries have also caught on to wind power, such as Germany and Spain.Most Texans are content to have wind turbines installed on their property. Instead of worrying about the cost of oil, they have a source of energy they can rely on right in their backyards.
