A wind farm is a group of wind turbines in the same location used for production of electricity. A large wind farm may consist of several hundred individual wind turbines distributed over an extended area, but the land between the turbines may be used for agricultural or other purposes. For example, Gansu Wind Farm, the largest wind farm in the world, has several thousand turbines. A wind farm may also be located offshore.

A wind farm is a group of wind turbines in the same location used for production of electricity. A large wind farm may consist of several hundred individual wind turbines, and cover an area of hundreds of square miles, but the land between the turbines may be used for agricultural or other purposes.

Wind power is one of the most promising renewable energy sources and wind farms are being built more frequently in many different regions of the world. A wind farm is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind generation of electricity is a renewable energy source that is increasingly competing with fossil fuel power plants. It is economically comparable to coal when it comes to cost in energy production.

As wind energy is an inexhaustible resource, it will continue to outperform other renewable energy sources in the coming years. Wind farms, unlike solar panels, produce electricity at all hours of the day and night without harming the environment. Wind energy provides a high social and environmental cost-benefit ratio, as well as a construction cycle that is quick, flexible in terms of investment, and requires low maintenance. Apart from all of these benefits, developing wind farms increases the availability of jobs in economically depressed areas and provides cost advantages over other large-scale power generation technologies. In power grids with integrated wind energy systems, wind speed is crucial for the energy market, system adequacy, and quality of service. In this paper, two popular time series prediction methods are combined to form a hybrid model for short-term wind speed prediction. In comparison to the individual models, the hybrid LSTM-ARIMA model combination performed better and achieved the least error metrics. This was demonstrated by applying 4 single models – Exponential Smoothing, ARMA, ARIMA & LSTM and 1 hybrid model – LSTM-ARIMA, to the hourly wind speed data of Tibau, Brazil in 2021, for 3 different lead times: 12-day, 2-day, and 1-day. The model achieved an RMSE and MAPE of 2.174 and 24.78% respectively for the 12-day time scale, 1.241 and 9.30% respectively for the 2-day scale, and 1.125 and 12.80% respectively for the 1-day scale. The higher prediction accuracy of this model indicates that when ARIMA and LSTM are added to the appropriate component, the corresponding model could contribute to improving the short-term wind speed accuracy for different lead times (Dong et al. 2020).
