“…Also, the wind speed has a small effect on the PMSG efficiency and this result is consistent with what was stated in the study efficiency of the PMSG within a range of wind speeds (12-14)m/sec., as its value reached 97% [70], and partly disagree with what was stated in the study at variable wind speed(8-10)m/sec.the PMSG efficiency was within limits of 91% [71], and the reason difference is due to the selection of variable and irregular speeds of wind speeds. The results of this paper are consistent with the efficiency of the permanent magnet motor, which was valued 96% [72]. Also, agree with the results of this paper with the efficiency of the permanent magnet machine that valued at 96% [73].…”

Considering the importance of optimizing renewable energy systems, this paper aims at calculating the exact efficiency of a stand-alone wind turbine connected to a synchronous generator with permanent magnet excitation (PMSG). By accounting for mechanical and electrical losses (copper losses, stray load losses, iron core losses, friction losses, windings losses, and magnetizing saturation effect), the study investigates the impact of wind speed on the generator's performance and efficiency in addition to the impact of losses on the overall efficiency of (PMSG). The simulation of the PMSG dynamic model 8.5×(10)^3 V․A is executed using MATLAB/Simulink, employing a simplified equivalent circuit that accurately represents the PMSG's behavior under steady-state conditions with resistive loads. Wind speeds of 12 and 14 meters/second are chosen as fixed values to demonstrate the effect of varying wind speed on efficiency. The obtained results reveal the influence of wind speed on the PMSG efficiency. The presented findings contribute to the understanding of PMSG performance and can aid in optimizing the stand-alone wind turbine systems, they also show that the wind had an effect on the efficiency values that were obtained (97.86% at 12m/s and 97.91% at 14 m/s), while the effect of losses was very few around 3%. However, the obtained results are very good compared to previous studies to show the accuracy and validity of the suggested dynamic model.

This paper presents a maximum efficiency algorithm (MEA), aiming at minimizing both copper loss and iron loss, for the interior permanent magnet synchronous motor (IPMSM) drive system. The equivalent circuit model is utilized to reach the optimal dq-current function with the optimal process. Besides, the current-voltage limitation algorithm for the MEA is proposed to solve the current limitation and the voltage limitation issues. The feasible region for the MEA is the intersection of the maximum current region and the maximum voltage region. With the IPMSM test platform, the validated experiments and efficiency tests were implemented to evaluate the proposed strategy. The experiments indicate the MEA operation is effective and feasible to improve the efficiency of the IPMSM. Besides, the feasible operating region of the IPMSM can be extended by the MEA. With the advantage of improving efficiency and extending the operating region, the MEA is suitable for applying the IPMSM drive system.
