Abstract

Among the different renewable, wind energy system is the most exploited due to its free availability and technological developments. With the increasing penetration of wind energy into power system, the grid codes are become effective which mean wind energy system must insure the uninterrupted operation with voltage control and reactive power compensation improving low voltage ride through capability(LVRT). The doubly fed induction generator (DFIG) based wind energy system is very sensitive to voltage variation and less ability to resist drop in grid voltage. To enhance the LVRT capability of DFIG, one of the series connected Flexible A.C. Transmission Systems (FACTS) device Static Synchronous Compensator (STATCOM) is proposed here. The STATCOM connected between the wind energy system and point of common coupling compensate accurately. When there is voltage difference between normal voltage and fault condition, difference will be generated by inverter modulation thus improving its LVRT. The simulation for 2MW wind energy system is carried out on Matlab/Simulink environment and results are verified.
