Wind Power Supply Stability Analysis

The stability of supply from wind power plant consisting of two wind turbines (2x 2 MW installed capacity) is analysed in this paper. The analysed data set contains of 50 days of 10 minute average records of power output for both turbines and wind velocity measured at each turbine. A confidence bounds were calculated for predicted power supply within next 10, 30 and 60 minutes. The confidence limits for probable power groth and decrease within next 10 minutes is also calculated for both of wind turbines, and for sum of turbines. Results show, that power supply is (in relative numbers) more stable from WPP as a whole, than from standalone turbines.
