Both the planning and operating of a wind farm demand an appropriate wind speed model of its location. The model also helps predict the dynamic behaviour of wind turbines and wind power potential in the location. This study characterises the wind speed se... see more

In this paper we analyzed the complexity of the time series of wind speed in Petrolina, Brazil at heights of 25 and 50 m. We applied the sample entropy (SampEn) method on wind speed temporal series for each month of 2010, in order to analyze the intra-ann... see more

The objective of this work was to evaluate the adjustment of data series of hourly wind speed for Ponta Grossa, Paraná State, to the probability distributions of Weibull, Rayleigh, Beta, Gama and Normal and to analyze possible interferences of the day and... see more

In this study, a new hybrid power plant designed to convert solar and wind energy into electricity. Wind speed and solar radiation measurements were made in the different sections of Mersin Province. In the designed power plant, the energy obtained by tra... see more

Accurate Wind speed forecasting has a vital role in efficient utilization of wind farms. Wind forecasting could be performed for long or short time horizons. Given the volatile nature of wind and its dependent on many geographical parameters, it is diffic... see more

Thermal energy is used in greenhouses for the temperature and humidity control.  In the North of Europe, energy expenditures have a significant share in the total greenhouse production cost.  A study was performed to quantify and analyze the use... see more

In Turkey, many enterprisers started to make investment on renewable energy systems after new legal regulations and stimulus packages about production of renewable energy were introduced. Out of many alternatives, production of electricity via wind farms ... see more

Both the planning and operating of a wind farm demand an appropriate wind speed model of its location. The model also helps predict the dynamic behaviour of wind turbines and wind power potential in the location. This study characterises the wind speed se... see more

The bivariate logistic model with two-component extreme value marginal distributions (BTCEV) is applied to provide a regional at-site wind speed estimate. The maximum likelihood estimators of the parameters were obtained numerically by using a multivar... see more
