This paper covers the estimation of the average yearly production of an appropriate wind turbine for different locations in Iran. The effects of topography, the influence of obstacles such as buildings and shelters, the collective effects of the surrounding terrain, roughness classifications, and orographic elements such as hills, cliffs, etc., all have been included in the calculations. A full...

This paper presents a hybrid neural network approach to predict wind speed automatically in renewable energy systems. Wind energy is one of the renewable energy systems with lowest cost of production of electricity with largest resources available. By the reason of the fluctuation and volatility in wind, the wind speed prediction provides the challenges in the stability of renewable energy syst...

The continuous power supply for rural areas can be possible by using renewable hybrid power generation system and also reduction of the energy storage devices for the system. The impact of the shortage of power supply probability, surpluspower power generation, ratio of the energy supply to load demand, renewable fraction of different types of energy resources (solar and wind) and the combined ...

The recent past has witnessed a rising demand of electric energy. The near future will see depletion in the fossil fuels like the coal, diesel and the petrol reserves, so emphasis has to be given on the renewable energy sources. Wind Energy has proven to be a significant option for the present energy resources. There is need for more analysis in the Wind energy sector so that it can be more rel...

The Western Wind and Solar Integration Study Phase 1 (WWSIS1) investigated the impacts of high penetrations of wind and solar power on the Western Interconnection of the United States. The Western Wind and Solar Integration Study Phase 2 (WWSIS2) built on Phase 1 but with far greater refinement in the level of data inputs and production simulation. It considered the differences between wind and...

Wind energy is one of the most promising renewable energy resources. Due to instantaneous variations of the wind speed, an appropriate Maximum Power Point Tracking (MPPT) method is necessary for maximizing the captured energy from the wind at different speeds. The most commonly used MPPT algorithms are Tip Speed Ratio (TSR), Power Signal Feedback (PSF), Optimal Torque Control (OTC) and Hill Cli...

wind power generation is variable and uncertain. in the power systems with high penetration of wind power, determination of equivalent operating reserve is the main concern of systems operator. in this paper, a model is proposed to determine operating reserves in simultaneous market clearing of energy and reserve by stochastic programming based on scenarios generated via monte carlo simulation ...

39  Abstract— Utilization of wind power as renewable resources of energy has been growing rapidly around the world in the last decades. Wind power generation is fluctuating due to the variation of the wind speed. Therefore, the assessment of the output power of this type of generators is always associated with some amount of uncertainties. The output voltage and frequency from the ac generator...

through this article, the distribution of air pollutants in tehran have been simulated based on wind patterns with and without the presence of synoptic by tapm (a meso-scale model). the simulation covers three horizontal resolution domains 30, 15 and 5 kilometers. the pollutants chosen for this are co and pm10 and wind data is 10 meter height level. the result has shown that the model simulated...
