“…The mathematical model of the wind turbine determines the optimum speed as a function of the wind speed. Various forms of the WT power curve, the PWT(ω,v) function, have been given in the literature [18][19][20][21][22][23]31]. Further, with regard to the WT power characteristic, the function P WT (ω) changes significantly with time and at varying wind speeds, and for high values of the equivalent moment of inertia J, it is difficult to determine the MPP coordinates.…”

“…The value of the optimum mechanical angular velocity, ω OPTIM , and the power at the electrical generator, P EG , depend on the value of the wind speed, v, which are generally [18][19][20][21][22] not well known. The maximum capture of wind energy can only be achieved with the correct mechanical angular velocity dependence on the wind speed [18][19][20]23,24].…”

“…As atmospheric conditions, mechanical stresses, and even turbine geometry change over time, the dependence of the mechanical angular velocity on the initially set wind speed changes over time and, therefore, requires recalculation based on the measurements [25]. At many sites [22,[26][27][28], energy efficiency is reduced due to the age of the turbine's calibration method, which uses invalid mathematical models.…”

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.
