摘要

The huge penetration of wind energy sources in the micro grid makes the grid operations more intrinsic. The intermittent nature of wind fluctuates the electrical power output of the wind generator. The battery storage mechanism are usually employed to mitigate these power fluctuations to an extend. This paper presents the modeling and control of grid connected wind driven Doubly Fed Induction Generator (DFIG) with Battery Energy Storage System (BESS) to mitigate the power fluctuations which arises due to the wind speed variations. Super capacitor is employed to improve the transient response and thus life of the battery. The battery State of Charge (SoC) is considered while charging and discharging of BESS. A 0.9 MW DFIG is simulated in PSCAD/EMTDC and verified the control schemes.
