The expanded integration of wind energy imposes technical challenges to maintain system reliability. In order to tackle these challenges, comprehensive reliability models for wind turbines and related factors are essential. Proposed algorithm classifies Wind Turbine Generator (WTG) components based on their impact on WTG output. There upon, the WTG has a composite three-state reliability model which...
Renewable energy sources like wind energy; attract the attention of electrical engineers for generating electricity in the recent years. There are two predominant elements that determine the output power of a wind farm; the wind speed and the wind turbine characteristic. In this paper the wind site location and wind turbine rated power; both are selected according to the reliability indices of power...
Wind energy has been considered to be one of the main participants in supplying global energy needs. Meanwhile reliability and availability are critical issues to be studied with high wind penetration. While previous studies have focused on steady state behavior of wind turbines, this paper presents a Markovian method to study time-based reliability of wind farms. This method considers wind speed,...
Renewable energy is increasingly being treated as a promising solution to the global warming and other environment issues. Due to the intermittent nature of these energy resources, energy storage is required to provide certain wind generation capacity. An analytical procedure is presented in this paper to analyze the impacts of energy storage on reliability of power systems with wind turbine generators...
The Romanian National Energy strategy is requesting that renewables quota to reach 33% of consumption in 2010 and 38% in 2020. One of the most challenging issues facing wind energy today is its maximal and reliable integration in the power markets. Due to transport/distribution grid lack of flexibility and high level of concentration in Dobrogea region of large wind developments the access to the...
Like conventional power plants, wind power plants must provide the power quality required to ensure the stability and reliability of the power system it is connected to and to satisfy the customers connected to the same grid. When wind energy development began, wind power plants were very small, ranging in size from under one megawatt to tens megawatts with less than 100 turbines in each plant. Thus,...
