Evaluation of the Wind Shear at a Site in the North-West of the Yucatan Peninsula, Mexico

A PV-Wind hybrid system has been developed at the energy Laboratory of the Autonomous university of Yucatan in order to evaluate the performance of this kind of generators in the tropical conditions of the North of the Yucatan Peninsula. The systems comprise a PV array, a wind generator, a battery bank and a set of electric regulators, converters and an inverter. The voltage and the electric current of the main components of the system have been studied monthly along with their corresponding diurnal cycles. This paper presents an outline of the PVWind hybrid energy generator and its main characteristics which will allow to evaluate strategies to improve the performance of independent energy generation systems from renewable resources in the study region.

“…The highest average wind speeds occur between March and May on the Yucatan Peninsula. Therefore, the results are consistent with the expected values [61]. It was also possible to find, with measured data, the frequency distributions at the two heights, as illustrated in Figure 4.…”

Influence of Atmospheric Stability on Wind Turbine Energy Production: A Case Study of the Coastal Region of Yucatan

Wind energy production mainly depends on atmospheric conditions. The atmospheric stability can be described through different parameters, such as wind shear, turbulence intensity, bulk Richardson number, and the Monin–Obukhov length. Although they are frequently used in micrometeorology and the wind industry, there is no standard comparison method. This study describes the atmospheric stability of a coastal region of Yucatan, Mexico, using these four parameters. They are calculated using six-month data from a meteorological mast and a marine buoy to determine atmospheric stability conditions and compare their results. The unstable atmospheric condition was predominant at the site, with an 80% occurrence during the measurement period, followed by 12% in neutral and 6% in stable conditions. Wind speed estimations were performed for each atmospheric stability scenario, and the variation in the energy produced was derived for each case. Unstable atmospheric conditions deliver up to 8% more power than stable conditions, while neutral conditions deliver up to 9% more energy than stable conditions. Therefore, considering a neutral state may lead to a considerably biased energy production estimation. Finally, an example calculation indicates that atmospheric stability is a crucial parameter in estimating wind energy production more accurately.

“…However, at night (cold temperature, low wind speed), the PLI is lower compared to that at night (hot temperature, high wind speed). On top of that, the vertical thermal convection, as highlighted by [54], is not the only way to determine the characteristics of climate or wind, but it can also be determined by the horizontal movement, which is produced by thermal circulation of the ocean breeze [55,56]. The movement of wind speed that is predominant could be visualized by using wind rose, as presented in Figure 6.…”

This paper investigated the wind energy potential by analysing a certain amount of gathered 10-min measured data at four stations located at coastal sites in Malaysia, i.e., Kudat, Mersing, Kijal, and Langkawi. The wind data are collected from a total of four new wind measurement masts with sensors mounted at various heights on the tower. The measured data have enabled the establishment of wind resource maps and the power law indexes (PLIs) analysis. In addition, the dependence of PLI upon surface temperature and terrain types is studied, as they are associated to the form of exponential fits. Moreover, the accuracy of exponential fits is assessed by comparing the results with the 1/7 law via the capacity factor (CF) discrepancies. In order to do so, the wind turbine with a hub-height similar to the maximum height of the measured data at each site is selected to simulate energy production. Accordingly, the discrepancy of CF based on the extrapolated data by employing 1/7 laws and exponential fits, in spite of being computed using measured data, is determined as well. Furthermore, the large discrepancy of the wind data and the CF, which has been determined with the application of 1/7, is compared to the exponential fits. This is because; discrepancy in estimation of vertical wind speed could lead to inaccurate CF computation. Meanwhile, from the energy potential analysis based on the computed CF, only Kudat and Mersing display a promising potential to develop a medium capacity of wind turbine power, while the other sites may be suitable for wind turbines at a small scale.
