“…The time variations in wind speed and velocity (mechanical angular velocity), i.e., the functions v(t) and n(t) and ω(t), are continuous and derivable functions. Due to the high mechanical inertia of wind systems [18,33,34], the speed changes slowly over time and it is not a problem to record the current wind speed variations at the site under study [33,35]. The wind speed also changes continuously over time and recording it does not pose any particular problem.…”

Wind turbines are one of the leading renewable sources of electricity. They are located in areas where the energy potential of the wind is high and more or less permanent. Their efficient operation depends on certain technical characteristics of the entire wind system (wind turbines, generator, automation system, regulation, and control). This paper analyses experimental data from wind turbines, WT, in the Dobrogea area: wind speed, v, velocity, n, and power, PEG, at the electric generator, EG. These are used to identify the local maxima of wind turbine power at different wind speeds. Based on this, a mathematical model for wind turbines and the power losses caused by inefficient control are determined. The mathematical model is used to visualize the maximum energy zones. At the end of this study, an algorithm is given that allows for the visualization of the optimal energy zone. The algorithm resulting from the analyzed case studies can be implemented by the control system in order to maximize the produced electricity with any variation in wind speed.
