Analysis on the Coordinated Control of Doubly Fed Induction Generator System and Battery Energy Storage

摘要

Maintaining stability is more tedious task when wind energy conversion system connected with power system grid. The mandatory work is to maintain stable and constant grid voltage irrespective of varying wind speeds. This ensures the synchronization of the system. Here Doubly Fed Induction Generator with optimized controllers make the system operation smoothen with different grid operations [1]. The coordinated control operation of doubly fed induction generator and batteries to rescue the entire system from the abnormal grid condition. This setup provides backup in heavy grid faults and also reduce the time of cascaded failures. Controller gains are optimized to ensure the coordination. The simulations are done in MATLAB Simulink environment.
