Small Signal Stability Analysis of Large Scale Variable Speed Wind Turbine Intergration

Abstract

Due to increase in the amount of pollution globally, modern power systems are incorporating renewable sources to generate electricity. Out of the several renewable sources, wind energy is gaining maximum height in terms of power generation in the present scenario. Out of the various wind turbine generators, the variable speed wind turbine generator or doubly fed induction generator is widely used since, the DFIGs are capable of offering higher efficiency in capturing the wind energy over a wide range of wind speeds, with better power quality. As the integration of wind energy is immensely increasing, it has become important to analyze the effect of wind generation on small signal stability. This paper thus, will thus discuss the small signal stability of large scale variable speed wind turbine with DFIG incorporation into modern power system. The small signal stability analysis is done following conventional eigen value or modal analysis method.
