“…The problems addressed in this paper are the mathematical modeling of wind turbines and the calculation of power losses for large variations in wind speed over time, which are fundamental in control design [18,33,34,36,37]. The mathematical model for a wind turbine (WT) is based on the WT power characteristic, the function between the wind speed, v, and the mechanical angular speed, ω, of the turbine, P WT (ω,v).…”

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.

Performance Improvement of Grid-Integrated Doubly Fed Induction Generator under Asymmetrical and Symmetrical Faults

et al. 2023

The doubly fed induction generator (DFIG)-based wind energy conversion system (WECS) suffers from voltage and frequency fluctuations due to the stochastic nature of wind speed as well as nonlinear loads. Moreover, the high penetration of wind energy into the power grid is a challenge for its smooth operation. Hence, symmetrical faults are most intense, inflicting the stator winding to low voltage, disturbing the low-voltage ride-through (LVRT) functionality of a DFIG. The vector control strategy with proportional–integral (PI) controllers was used to control rotor-side converter (RSC) and grid-side converter (GSC) parameters. During a symmetrical fault, however, a series grid-side converter (SGSC) with a shunt injection transformer on the stator side was used to keep the rotor current at an acceptable level in accordance with grid code requirements (GCRs). For the validation of results, the proposed scheme of PI + SGSC is compared with PI and a combination of PI with Dynamic Impedance Fault Current Limiter (DIFCL). The MATLAB simulation results demonstrate that the proposed scheme provides superior performance by providing 77.6% and 20.61% improved performance in rotor current compared to that of PI and PI + DIFCL control schemes for improving the LVRT performance of DFIG.

“…The ministry plans to collaborate with renewable energy companies like Siemens to implement $14 billion in projects, including a wind atlas and a 400 MW wind farm in Iraq, despite ongoing consideration from the Iraqi side [1]. The operation, control, and difficulties of converters are the main topics of this paper's review of their effects on the conversion of wind energy.…”

This work looks into Iraq's best places for wind turbines, with an emphasis on economic factors. It studies wind energy conversion systems using mathematical models from Matlab and Simulink. This research aims to pinpoint areas where wind energy can produce power on its own, separate from the national grid, for a range of applications, including energy storage, water pumps, heating, and cooling. In addition, the project will use PMSG to investigate wind turbine efficiency and create vector control technique technology for permanent magnet synchronous generators. Two Iraqi cities were taken to make the calculations of wind speed and its effect on electrical generations (Nasiriyah and Basra), where wind speeds of a height of 20 and 50 m were taken at the hub level of the turbine. The mechanical, electrical, and performance characteristics of the turbine were computed during the test to achieve optimal operation cases. The development of the system was done by MATLAB SIMULINK, where the overall efficiency was enhanced to 88.22%.
