Increasing the penetration of variable wind generation in power systems has created some new challenges in the power system operation. In such a situation, the inclusion of flexible resources which have the potential of facilitating wind power integration is necessary. Demand response (DR) programs and emerging utility-scale energy storages (ESs) are known as two powerful flexible tools that ca...

This paper treats an induction machine as a wind power generator, and voltage deviation due to wind velocity change is simulated by a dynamic stability calculation program. The ac bus voltage connected to the wind generator highly depends on the wind velocity variation. Then author actually measured the wind velocity which is used for the simulation. This paper shows 1 second sampling data of t...

A wind farm is a collection of wind turbines built in an area to provide electricity. Wind power is a renewable energy resource and an alternative to non-renewable fossil fuels. In this paper impact of wind farms in power system reliability is investigate and a new procedure for reliability assessment of wind farms in HL1 level is proposed. In proposed procedure, application of Fuzzy – Markov f...

Recently renewable energy resources especially wind power integration has been far increased in the electric power distribution system. To utilize wind power more effectively, wind energy conversion system is interfaced to grid through power electronics interfaces. In this paper, monitoring of various power quality disturbances at the point of common coupling in grid connected wind energy conve...

The shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. In reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a S-shape profile. The pr...

A method for numerically simulating a three-dimensional field of turbulent windspeed (the “Sandia method”) for use in the aerodynamic and structural analyses of wind turbines is presented. The required inputs are single point power spectral densities (PSDs) and the coherence function. Suggestions for appropriate inputs and an example calculation are included. The simulation method is used to ob...

There is a substantial increase in energy demand in Turkey because of its growth of industrial development. Turkey’s present energy resources are insufficient and the need for energy is growing rapidly. Turkey does not possess enough conventional fossil fuel reserves, but possesses rich renewable energy resources such as hydraulic, solar, geothermal and wind. Among all, wind energy seems to be ...

Abstract The ability to accurately assess renewable energy resources is an essential prerequisite to integrating renewable energy technologies into the energy supply portfolio of a community. This study investigates the potential for wind energy development in Guelph, a growing mid-size city in Southern Ontario, Canada. Community awareness of energy has led to the development of a Community Ene...

In this paper, a two-stage stochastic unit commitment (UC) model considering flexible scheduling of demand response (DR) is proposed. In the proposed UC model, the DR resources can be scheduled: (1) in the first stage, as resources on a day-ahead basis to integrate the predicted wind fluctuation with lower uncertainty; (2) in the second stage, as resources on an intra-day basis to compensate fo...
