The continuous increasing in the pollution level and in the same time
increasing in fuel price are factors which lead to the increase in using
renewable energy sources specially wind energy. Wind energy faces many
challenges, one of the important challenges is that of the rapidly change in
wind speed which depends on the weather condition. A change in wind
speed affects on the generated power from wind turbine. SCIG and DFIG
are famous kinds of wind turbine, Each of them has advantage and
disadvantage, SCIG is cheap but its operation has a great effect on system
stability, especially when it operates without static synchronous
compensator. DFIG keeps the system stable but it is very expensive.
Therefore, it's necessary to examine the response of different wind turbine
generators variation of gust wind speed. This paper investigates the ability
of hybrid wind farm which consists of SCIG and DFIG to operate without
static synchronous compensator under gust wind speed condition. The
gust wind speed is simulated according to the International
Electrotechnical Commission IEC 61400.
