Abstract

Wind power using a Doubly Fed Induction Generator (DFIG) is widely used due to its many outstanding features. However, in the microgrid (MG) in off-grid mode, the DFIG needs support from other sources to be able to work stability. This paper proposes a model of DFIG combined with a battery energy storage system capable of self-maintaining grid voltage and frequency during isolation from the system grid. The converter control system attached to the BESS is built to increase the flexibility of the proposed model, taking into account the state of the system grid, local load needs, and allowable capacity of the BESS, as well as the wind speed. This paper also simulated and analyzed the results when the microgrid disconnected from the system grid on the tool Matlab/Simulink. The frequency and voltage response of the proposed model, when isolation occurs, are completely within the allowable limits.
