چکیده

A method for prediction of wind speed at a selected location based on the data collected at neighborhood locations is presented. The affinity of wind speeds measured at different locations is defined by Pearson’s correlation coefficient. Five turbines with similar wind conditions are selected among 30 wind turbines for in-depth analysis. The wind data from these turbines are used to predict wind speed at a selected location. A neural network ensemble is used to predict the value of wind speed at the turbine of interest. The models have been tested and the computational results are discussed. The results demonstrate that a higher Pearson’s correlation coefficient between the wind speeds measured at different turbines has produced better prediction accuracy for the same training and test scenario. & 2010 Elsevier Ltd.

Robust Controller Design for IG Driven by Variable-Speed in WECS Using μ-Synthesis

This paper presents robust controller design for a wind-driven induction generator system using structured singular value ( -synthesis) method. The controller was designed for a static synchronous compensator (STATCOM) and a variable blade pitch angle in a wind energy conversion system (WECS) in order to achieve the required voltage and mechanical power control. The results indicated that this ...

Evaluation of Optimal Fuzzy Membership Function for Wind Speed Forecasting

In this paper, a new approach is proposed in order to select an optimal membership function for inputs of wind speed prediction system. Then using a fuzzy method and the stochastic characteristics of wind speed in the previous year, the wind speed modeling is performed and the wind speed for the future year will be predicted. In this proposed method, the average and the standard deviation of in...

Natural Ventilation: Analysis of Indoor Airflow in an Assumed Cubic Building with Opposite Openings by CFD Investigations

The natural ventilation is an easy way to exchange the indoor polluted warm air with outdoor fresh air. The wind power injects outdoor fresh air into the building. A good indoor air current and subsequently a proper exhaust depend on the openings’ conditions and their situations. A serious architectural question is under what conditions of the openings the wind-cross ventilation can be effectiv...
