New Software for Matching Between Wind Sites and Wind Turbines Ali M. Eltamaly Abstract Wind energy system is becoming a mature technology for generating electric energy from the wind. The design of the wind energy system should take into consideration the matching between the wind speed site characteristics and the performance characteristics of the wind turbine. This chapter is introduced to perform the matching process between the site and the wind turbines (WTs) for minimum cost and highest reliability. An accurate matching methodology for pairing between site and WTs has been introduced. The pairing methodology is designed in Matlab code to perform this study. The input data for 32 Saudi Arabia sites and 140 market available WTs have been selected to validate the right operation of the new proposed computer program. This program will select the best site and the most suitable WT for this site based on techno-economical methodology. This program can help researchers, designers, experts, and decision-makers to select the best site among many sites and the best WT for each site. The results obtained from this site show a substantial reduction in cost when the best site is selected as the most suitable WT for this site. 1 Introduction Wind turbines (WTs) have different technologies and different performance charac- teristics. At the same time, wind speed characteristics of sites are different from one site to another. Where one WT can generate high energy in some sites, meanwhile it may generate lower energy in some other sites because of the correlation between the wind turbine performance parameters and site parameters. To get the minimum cost of energy the suitable WT should be selected for minimum cost. This operation is called a pairing between the site and the WT. Based on this speed the suitable WT A. M.
