Research and Analysis of the Impact of Local Climatic Conditions on Wind Turbine Generation—Case Study

The increasing number of wind turbines in sparsely populated areas poses significant challenges to the security of the power system. The need for centralized control of unstable sources such as wind turbines and PV installations makes it significantly more difficult to maintain operational stability. The subject matter of wind power plant research can be divided into three groups: wind prediction and productivity forecasts, optimization of the energy generation process, and the impact of power plants on the system and the environment. The subject matter of this article falls within the scope of research on the first group, namely, the impact of wind on actual power production. This study presents the results of a year-long investigation of the Enercon E48 wind turbine located in northeastern Poland. The influence of wind speed and direction on the actual turbine output was analyzed and compared with the manufacturer’s power curve. The findings indicate that the actual performance of the turbine exhibits greater variability than suggested by catalog data, with local conditions and seasonal effects exerting a significant influence on its efficiency.
