The wind farm output power have the characteristics of dynamic, random, large capacity etc, which brought great difficulty for incorporating the wind farm in the bulk power system. In order to rationally regulate the power supply system in large grid connected wind power system and reduce the spinning reserve capacity of the power supply system and operating costs, it is necessary to forecastin...

Renewable energy facilities will constitute a major contribution to electrical power in the future. The wind turbine will, together with biomass, form the major renewables parts up to year 2030 including erection of offshore wind farms. The wind is a non-storable energy source, whose electric energy needs priming into interchangeable energy to be competitive for large-scale power generation. An...

Based on measured and forecasted wind power output it is possible to perform an analysis to assess the fluctuations of wind power generation in power systems. This report consists of two approaches for the analysis and assessment of wind power fluctuations. The first approach consists of a statistical analysis in which the power fluctuations of wind power output were determined by the calculati...

The IEA WIND Task 25 also known as the " Design and Operation of Power Systems with Large Amounts of Wind Power " , Task 25 of IEA Implementing Agreement on Wind Energy, functions within a framework created by the International Energy Agency (IEA). Views, findings and publications of IEA WIND Task 25 do not necessarily represent the views or policies of the IEA Secretariat or of all its individ...

This work assesses the participation of wind power plants in primary frequency control support. To participate in frequency control-related tasks, the wind power plants have to maintain a certain level of power reserves. In this article, the wind power plant is equipped with a flywheel-based storage system to fulfil the power reserve requirements set by the network operator. The article focuses...

The new grid regulations require that a grid-connected wind farm acts as a single controllable power producer. To meet this requirement a traditional wind farm control structure, which allowed individual wind turbines to internally define their power production, has to be modified. This paper investigates the opportunity for wind turbine load reduction that arises from dynamic power control of ...

Using the FACTS controllers, such as static synchronous compensator (STATCOM), as it provides continuous reactive power, in the grid including wind turbine (WT) equipped with doubly fed induction generator, for improving voltage profile (under normal circumstances) and providing a transition ability from inductor generator transition state has been proposed. In this paper, in order to contr...

The Weibull probability distribution has been widely applied to characterize wind speeds for wind energy resources. Wind power generation modeling is different, however, due in particular to power curve limitations, wind turbine control methods, and transmission system operation requirements. These differences are even greater for aggregated wind power generation in power systems with high wind...

Wind turbine manufacturers publish and certify power curves for their turbines. These turbine power curves are used for planning purposes and estimating total wind power production. When a wind plant consisting of many turbines connects to the utility grid and starts operation, the focus shifts to the entire plant’s performance. An equivalent wind plant power-curve becomes highly desirable and ...
