This paper describes a direct power control (DPC) strategy used for a doubly fed induction generator (DFIG) for wind energy system. The system operates in stand-alone (SA) and can connect to the grid through smooth transition. The proposed control structure is capable of regulating the stator voltage and frequency for an isolated load in case of grid outage. Also, when grid is available, it can control...
The direct power control (DPC) scheme for doubly-fed generator (DFIG) wind energy systems is known to have simple control structure and fast dynamic response in comparison with other well developed control approaches such as field oriented control (FOC). The simplicity of this method comes from employing hysteresis-based controls for the stator active and reactive powers. However, these controllers...
