In order to investigate the impacts of wind power integration on the low frequency oscillation characteristics of an interconnected power system

the damping performances of a two-area interconnected power system with and without wind power integration are analyzed based on the comprehensive model of the doubly fed induction generator (DFIG). The impacts of several factors

including the DFIG transmission distance

DFIG capacity

tie-line power of the interconnected system

with/without a power system stabilizer (PSS)

on the low frequency oscillation characteristics of the interconnected power system are examined systematically. Then

a two-area four-generator system and a two-area eight-generator system are employed to carry out detailed analysis and comparisons. Simulation results show that the impacts of these factors on the low-frequency oscillation modes are different for various system operating scenarios

and hence it is necessary to comprehensively consider these factors in the plan

design

and operation of wind power integration into an interconnected power system.
