Analysis of electric power generation characteristics for hybrid power system combining wind farm with gas turbine

The power output characteristics of a complementary generation system combining a large-scale wind farm and gas turbine power plants was analyzed. And the calculation equations of generation parameters were derived from the basic principles of hybrid power system. Based on the sampling data of wind speed in Dabancheng, Sinkiang and the whole power curve of wind farm, several key parameters such as the total delivered electricity and capacity factor were calculated. According to the operation strategies and part-load efficiency of the system, the total delivered electricity, consumption of the natural gas and capacity factor of the gas turbine were also calculated. The relative parameters of hybrid power system were derived. Moreover, the effect of different wind resource characteristics in wind farm on the power system were discussed and analyzed; The techno-economic analyzing basis of the hybrid power system in Sinkiang region has been provided.
