Wind energy has recently become the most cost-effective and environmentally friendly amongst other renewable energy resources. However, since wind resource is intermittent in nature, the wind power output is inconsistent. Therefore, a control system needs to be implemented to ensure that maximum power is extracted from the wind resource at a wide range of wind speeds to optimize the performance of...
A novel control strategy for the operation of a permanent magnet synchronous generator (PMSG) based stand alone variable-speed wind energy system is presented in this paper. The direct drive PMSG is connected to the load through a unity power factor current-controlled rectifier, which offers features such as high power factor operation, voltage regulation ability, low switching voltage stress and...
This paper proposes a simple technique to get maximum power of wind energy conversion system (WECS) without using sensors for wind and rotor speed of the permanent magnet synchronous generator (PMSG). It uses the measurements of DC current and DC voltage to obtain maximum power point tracking (MPPT) by controlling the duty cycle of the DC-DC boost converter switch. Moreover, a PI control is employed...
