Wind energy is a major source of power in over 70 countries across the world, and the worldwide share of wind energy in electricity consumption is growing. The introduction of significant amounts of wind energy into power systems makes accurate wind forecasting a crucial element of modern electrical grids. These systems require forecasts with temporal scales of tens of minutes to a few days in ...

This paper is a part of a research project to study the dynamics and control of distributed resources (DRs) in the deregulated electric power industty’. It reflects the need to look at large wind farms as power plants, as a result of the increased penetration of wind energy in the power systems many places in the world. To obtain an optimal integration of high penetration of wind energy in the ...

The inherent variability and randomness of large-scale wind power integration have brought great challenges to power flow control and dispatch. The distributed power flow controller (DPFC) has the higher flexibility and capacity in power flow control in the system with wind generation. This paper proposes a multi-time scale coordinated scheduling model with DPFC to minimize wind power spillage....

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...

Wind energy is producing a larger share of power on many utility grids as more wind turbines are installed, providing motivation for wind turbines to provide ancillary services that are necessary for power grid reliability. The ancillary services considered in this paper consist of actively controlling the power output of the wind turbines to track power set-point commands, participate in frequ...

An atmospheric boundary layer wind tunnel was used to survey the variation in local wind conditions over a region of the Altamont Pass, California, containing two wind farms. Meteorological data combined with the wind tunnel results were used to predict the power output of the wind farms every half hour over a oneyear period from July 2001 to June 2002. It was observed that the power production...

The power generated by wind generators is usually associated with uncertainties, due to the intermittency of wind speed and other weather variables. This creates a big challenge for transmission system operators (TSOs) and distribution system operators (DSOs) in terms of connecting, controlling and managing power networks with high-penetration wind energy. Hence, in these power networks, accura...

The integration of renewable wind and pumped storage with thermal power generation allows for dispatch of wind energy by generation companies (GENCOs) interested in participation in energy and ancillary services markets. However, to realize the maximum economic profit, optimal coordination and accounting for reduction in cost for environmental emission is necessary. The goal of this study is to...

The wind energy conversion system (WECS) differs from other power systems. It is clean and pollution free. But the output of wind power plant is fluctuated in nature. It depends on the wind speed. The nature of wind is variable. The variable wind generates fluctuated power. Fluctuated output is the major problem of wind power plant. This problem can be solved by using convertor units. The secon...

Wind power generation systems influence power quality in a specific way making important the need for detailed and accurate evaluation of disturbances caused by wind generators. Wind power system can cause suband interharmonic components to appear in the spectrum of voltages and currents. The paper shows different aspects of spectrum estimation in power systems, including the doubly fed inducti...
