Summary
This article presents a new wind energy system using 2 five‐phase permanent magnet synchronous generators (PMSGs) controlled by a fifteen‐switch rectifier (FSR) topology for grid‐connected system. The 2 five‐phase PMSGs are connected to the DC link through a FSR; at its turn, the DC link is connected to the grid through a classical three‐phase inverter. In order to boost the control performance of the proposed wind system, a sliding mode control is adopted to control both generators‐side and grid‐side converters. The proposed control is tested under varying wind velocity and compared with a proportional‐ and integral (PI)‐based control system. The obtained simulation results show that the controlled variables follow their references independently of the wind speed fluctuations; and there is a significant reduction in the speeds overshoots by 100% and in the DC‐link voltage ripples by more than 78%. In addition, the total harmonic distortion (THD) of the generated current and grid current are reduced to 7.19% and 47.80% compared with PI regulators, respectively.
