Dynamic simulation for wind farm in a large power system

As the sources of fossil energy decrease and demands for electricity increase, wind energy gains more and more importance throughout the world. Increasing wind power generation into power system is desirable because of its advantages: abundant, low cost, inexhaustible, widely distributed and clean attributes. However, reactive power consumption is one of the major problems of wind turbine that cause serious voltage stability problem, which also deteriorates power quality. Therefore when integrating a wind farm into the power system, one must guarantee the voltage stability, as well as the capability of the wind farm to survive large transients. This study explores the impacts of integration of wind turbine with different capacities and in different locations on the voltage quality and transient stability with different disturbances in the network. Simulations of steady state operation and transient faults are carried out in MATLAB/Simulink/Simpower System. The power system model in this study is based on the IEEE 30 bus 6 generator test system. The model for wind turbine in the simulation is induction generator (IG) available in Simulink library.
