Windpower is considerably increasing in many countries worldwide. Unfortunately, windfarm produces unreliable output due to the vagaries of the wind profile and so can not meet demand. Without action these would be major problems with fluctuating power quality. Wind energy source needs local support from conventional sources. The requirements concerning the reliability and quality of electric energy supply can be most satisfactory fulfilled when a windfarm is connected to a large electric power system. A strict cooperation is required between the large power system control and the windfarm control system to provide among others that any fluctuations of windpower supply should be damped as near to the windfarm as possible to avoid considerable disturbances of frequency and voltage in the electric power system. The distance between a windfarm and a large electric power system is very often too long to build a transmission line on an economically sound basis. It becomes unavoidable to produce windpower in a separate electric power system. Any fluctuations of windpower have to be damped due to an appropriate action of a conventional power plant support. To provide such a support the following aid concepts are possible: gas turbine power plant, diesel engine power plant, pumped storage power station. Investigation on the control of a separate electric power system composed of windpower farm and gas turbine power plant have been carried out. Effects of turbulence in the wind different amplitude and frequency of wind speed variations on gas turbine power plant control system have been simulated. The gas turbine power plant control system structure and parameters have been adopted to provide limiting the power and frequency fluctuations resulting from wind turbulence.
