In this paper, the training needs of wind farm employees have been specified, assessed and prioritized. For this purpose, first of all, the main tasks of wind farm employees have been identified. Afterwards, four criteria—including task complexity, task importance, task time duration and task frequency—have been considered to assess and prioritize tasks. In this respect, the Analytic Hierar...

This paper aims to explore a viable solution for a doubly-fed induction generator (DFIG)-based wind farm to meet the reactive support requirement of the low voltage ride-through (LVRT) grid code with safe grid-connected operation during asymmetrical grid faults. First, the control scheme for the DFIG-based wind energy conversion system (WECS) is designed. Then, the controllability issue is anal...

We investigate the use of optimal coordinated control techniques in large eddy simulations of wind farm boundary layer interaction with the aim of increasing the total energy extraction in wind farms. The individual wind turbines are considered as flow actuators, and their energy extraction is dynamically regulated in time, so as to optimally influence the flow field. We extend earlier work on ...

Understanding the context in which local wind farm development has been accepted by the local community is important for meeting the United States’ wind energy goals. To further this understanding in the rural Midwest, we investigated three counties in Indiana with varying levels of wind farm development using a mail survey, stakeholder interviews and a review of local newspaper articles and go...

Outdoor and indoor microphone measurements have been taken in the vicinity of the Waterloo wind farm at a number of locations during periods when the nearby wind farm was operational as well as when it was shutdown. The majority of the shutdowns were of short duration and deliberate on the part of the wind farm operator, as they were associated with the recent EPA noise impact study. However, o...

We analyze the cost of curtailing the active power output of a wind farm to provide secondary frequency regulation capacity. We calculate the regulation capacity available and its cost by simulating the active power output of a curtailed 100-MW wind farm with a hybrid of real speed data and simulated high-frequency turbulence. We find that a curtailed wind farm can provide secondary frequency r...

The recent past has witnessed a rising demand of electric energy. The near future will see depletion in the fossil fuels like the coal, diesel and the petrol reserves, so emphasis has to be given on the renewable energy sources. Wind Energy has proven to be a significant option for the present energy resources. There is need for more analysis in the Wind energy sector so that it can be more rel...

Doubly Fed Induction Generators DFIG are nowadays widely used in variable speed wind power plants. The dynamic interaction between variable speed DFIG wind turbines and the power system which is subjected to disturbances, such as short circuit faults, is an important issue. The ability of the wind power plant to stay connected to the grid during disturbances is important to avoid a cascading ef...

In late 2007, after signing the Kyoto Protocol, a new Australian federal government committed to generating 20% of Australia's electricity from renewable energy by 2020, for a transition to a low-carbon economy. With wind energy the most viable technology for such expansion, little recognition, however, was paid to intense social conflict surrounding wind farm location. By 2006, inadequate comm...

Under the framework of intelligent management of power grids by leveragingadvanced information, communication and control technologies, a primary objectiveof this study is to develop novel data mining and data processing schemes for severalcritical applications that can enhance the reliability of power systems. Specifically,this study is broadly organized into the following ...
