Book excerpt: Windmills have been used for at least 3000 years, mainly for grinding grain or pumping water, while in sailing ships the wind has been an essential source of power for even longer. From as early as the thirteenth century, horizontal-axis windmills were an integral part of the rural economy and only fell into disuse with the advent of cheap fossil-fuelled engines and then the spread of rural electrification. To use wind energy efficiently and to concentrate the visual impact of modem wind turbines, the regions with a good wind climate, a tendency to group turbines in wind farms can be observed. These wind farms are connected to high voltage transmission grids and thus directly influence the dynamic behavior of the electrical power system [1]. Modern electricity-generating wind turbines now use three-bladed upwind rotors although two-bladed, and even one-bladed, rotors were used in earlier commercial turbines. Reducing the number of blades means that the rotor has to operate at a higher rotational speed in order to extract the wind energy from wind turbine. Initially these turbines were small, sometimes rated at only 30 kW, but were developed over the next 15 years to around 40-m diameter, 800-1,000 kW. However, by the mid-1990s it was becoming clear that for larger wind turbines it would be necessary to move away from this simple architecture and to use a number of the advanced concepts (e.g. variable-speed operation, pitch regulation, advanced materials) that had been investigated in the earlier research work. Large wind turbines are up to 100 m in diameter, rated at 3 to 4 MW are used. Most of the largest wind turbines now being installed operate at variable-speed, as the power electronic converters also allow much greater control of the output power and it is easier to comply with the requirements of the power system network operator.

Download or read book Study of Power Quality Issues in Grid Connected Wind Farms written by T. Magesh and published by Independent Author. This book was released on 2023-04-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for electricity is increasing day by day and the power utilities are now exploring various alternatives for increasing the generation of electricity to meet the increased demand. Increasing the generation of electricity using fossil fuels leads to increased atmospheric pollution mainly due to the emission of carbon dioxide (CO2). Minimization of green house effect by reducing CO2 and other emissions is a challenging issue today. Alternate energy sources, on the other hand, are gaining popularity over the conventional energy sources as they are environment friendly. Renewable energy sources, such as solar and wind energy, help in reducing the dependence on fossil fuels thereby reducing the green house gas emissions. Wind energy generation systems are becoming more popular, nowadays, as they are the most competitive and environment friendly. Large numbers of wind turbines are erected around the world and many projects are under progress. In 1980s, wind turbine power ratings were few tens of kilowatts only whereas today, wind turbine ratings are in megawatts.
Download or read book Control and Operation of Grid Connected Wind Farms written by John N. Jiang and published by Springer. This book was released on 2016-05-31 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the point of view of grid integration and operation, this monograph advances the subject of wind energy control from the individual-unit to the wind-farm level. The basic objectives and requirements for successful integration of wind energy with existing power grids are discussed, followed by an overview of the state of the art, proposed solutions and challenges yet to be resolved. At the individual-turbine level, a nonlinear controller based on feedback linearization, uncertainty estimation and gradient-based optimization is shown robustly to control both active and reactive power outputs of variable-speed turbines with doubly-fed induction generators. Heuristic coordination of the output of a wind farm, represented by a single equivalent turbine with energy storage to optimize and smooth the active power output is presented. A generic approximate model of wind turbine control developed using system identification techniques is proposed to advance research and facilitate the treatment of control issues at the wind-farm level. A supervisory wind-farm controller is then introduced with a view to maximizing and regulating active power output under normal operating conditions and unusual contingencies. This helps to make the individual turbines cooperate in such as way that the overall output of the farm accurately tracks a reference and/or is statistically as smooth as possible to improve grid reliability. The text concludes with an overall discussion of the promise of advanced wind-farm control techniques in making wind an economic energy source and beneficial influence on grid performance. The challenges that warrant further research are succinctly enumerated. Control and Operation of Grid-Connected Wind Farms is primarily intended for researchers from a systems and control background wishing to apply their expertise to the area of wind-energy generation. At the same time, coverage of contemporary solutions to fundamental operational problems will benefit power/energy engineers endeavoring to promote wind as a reliable and clean source of electrical power.
Download or read book Low Voltage Ride Through Enhancement of Grid Connected Wind Farms written by Kenneth Eloghene Okedu and published by LAP Lambert Academic Publishing. This book was released on 2012-03 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fast growth of wind generation has led to concern about the effect of wind power on the transient stability of the electric grid. New studies must be performed in order to evaluate the behaviour of the wind farms after severe faults and improve the design of the wind farms in an efficient and economical way. Under such circumstances, the most demanding requisite for wind farm is the Fault Ride-Through (FRT) capability. Wind farms connected to high voltage transmission system must stay connected when a voltage dip occurs in the grid, otherwise, the sudden disconnection of great amount of wind power may contribute to the voltage dip, with terrible consequences. Therefore, the dynamic and transient analyses of wind generators are necessary. This book proposes some methods with suitable control strategies for wind power application that helps wind farms to be connected during grid disturbances, achieving the grid code provisions in both steady and transient conditions. The results in this book can be significant in understanding the transient stability phenomena of fixed and variable speed wind turbines and also in designing of wind farms based on transient stability requirements.

Download or read book Grid Connected Distributed Wind Photovoltaic Energy Management written by Sasmita Behera and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy management comprises of the planning, operation and control of both energy production and its demand. The wind energy availability is site-specific, time-dependent and nondispatchable. As the use of electricity is growing and conventional sources are depleting, the major renewable sources, like wind and photovoltaic (PV), have increased their share in the generation mix. The best possible resource utilization, having a track of load and renewable resource forecast, assures significant reduction of the net cost of the operation. Modular hybrid energy systems with some storage as back up near load center change the scenario of unidirectional power flow to bidirectional with the distributed generation. The performance of such systems can be enhanced by the accomplishment of advanced control schemes in a centralized system controller or distributed control. In grid-connected mode, these can support the grid to tackle power quality issues, which optimize the use of the renewable resource. The chapter aims to bring recent trends with changing requirements due to distributed generation (DG), summarizing the research works done in the last 10 years with some vision of future trends.
