Wind power generation is one of the good solutions to ensuring a clean and sustainable energy source. In recent years, therefore, many facilities for wind power generation have been constructed in Japan. In contrast to its advantage, however, residents in some areas near a wind power generation site have complained that their well-being has been disturbed by noise from wind turbines. Wind turbi...

Wind farm micro-siting is a complex process that requires multidisciplinary analysis and optimization. The problem consists not only of positioning the wind turbines in the locations within the site that have the most wind energy potential, but also it has to minimize wake interference between turbines. This means that usually the sum of the expected isolated turbines is less than the actual pe...

The growing use of wind energy as major energy source, has led to the construction of large wind farms. The control of such wind farms is typically separated into control at wind turbine level and at wind farm level. The wind farm controller assures that the wind farm produces the demanded amount of power, by providing set-points for the turbines in the farm. The local turbine control assures t...

Wind-photovoltaic hybrid system (WPHS) utilization is becoming popular due to increasing energy costs and decreasing prices of turbines and photovoltaic (PV) panels. However, prior to construction of a renewable generation station, it is necessary to determine the optimum number of PV panels and wind turbines for minimal cost during continuity of generated energy to meet the desired consumption...

Planning of modifications of existing wind farms by adding or replacing turbines makes new demands on wind farm modelling. Emphasis shifts from the calculation of the mean efficiency of the farm to that of individual turbines. Additionally, modelling has to deal with different turbine types and hub heights combined in one farm. Full scale measurements at two wind farms in Northern Germany provi...

Wind energy is undergoing expansion, and it is bound to grow to a commercial/consumer level in the decades to come. This growth has materialized in the form of large-scale wind farms, wind energy cooperatives, wind turbines owned by individual investors, and multinational exploration of remote sites and offshore locations. Despite the increasing rated capacity of wind turbines, operation and ma...

Wind-power development in the U.S. occurs primarily on private land, producing royalties for landowners through private contracts with wind-farm operators. Texas, the U.S. leader in wind-power production with well-documented support for wind power, has virtually all of its ~12 GW of wind capacity sited on private lands. Determining the spatial distribution of royalty payments from wind energy i...

As a result of increasing environmental concern, more and more electricity is generated from wind turbines. Therefore, adequate models to study the impact of wind turbines on electrical power system behavior are needed. One of the most important considerations is the effect of wind turbines on the voltage profile, i.e. the induced slow voltage variations, which are the subject of this paper. Th...

Despite common characterizations of modern wind energy technology as mature, there remains a persistent disconnect between the vast global wind energy resource—which is 20 times greater than total global power consumption—and the limited penetration of existing wind energy technologies as a means for electricity generation worldwide. We describe an approach to wind energy harvesting that has th...
