Wind energy represents one of the least cost methods of electricity generation, produces no carbon emissions, and is highly scaleable. However, the intermittency of wind and the passive reaction of wind turbines means spinning and scheduled reserves are required to ensure grid security. It is vital for transmission network planning that temporally and spatially accurate models of wind power are...

For the first time, global ocean usable wind power is evaluated for modern offshore turbine characteristics including hub height, usable portion of the wind speed distribution and siting depth. Mean wind power increases by 30%, 69% and 73% within the tropics and northern and southern hemisphere extratropics, respectively, between hub heights of 10 m and 100 m. A turbine with a cut-out speed of ...

The intermittency of wind resources may appear as an important handicap for integrating large-scale wind power in existing grids. However, in Canada and the United States, studies show that coordination between interconnected power systems can be economically beneficial for both the wind power and electric utility industries if some power system management and market rules are applied. In order...

In recent years, there has been introduction of alternative energy sources such as wind energy. However, wind speed is not constant and wind power output is proportional to the cube of the wind speed. In order to control the power output for wind power generators as accurately as possible, a method of wind speed estimation is required. In this paper, a technique considers that wind speed in the...

The increasing concern of global climate changes, the promotion of renewable energy sources, primarily wind generation, is a welcome move to reduce the pollutant emissions from conventional power plants. Integration of wind power generation with the existing power network is an emerging research field. This paper presents a meta-heuristic algorithm based approach to determine the feasible dispa...

It’s important to realize, optimized dispatching of generating units would be useless without a method of control. Frequency regulation in interconnected network is one of the main challenges posed by wind turbine in modern power system. Obviously the method of load frequency control (LFC) plays a vital role in large interconnected power system. However the modern LFC should be able to handle c...

a detailed model of wind power station, including double fed induction generator, dfig is presented in this paper. two control mechanisms are included in the model. the inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. the outer control system is used for wind turbine pitch angle. pscad/emtdc is used ...

-Wind Energy is one of the cheapest available renewable sources of energy. Now-a-days the demand for electricity increases drastically. A number of wind farms are already in operation and more are planned or under construction due to the increasing demand of the bulk amount of the electricity. It is must to identify the interactions between the Wind Turbines and the Power System. Here the Power...
