- Abstract
- This thesis presents the characteristics of output power generation at Haeng-won wind farm in Jeju and how to control the output power of wind farm with BESS for stabilizing power by using the actual data of Haeng-won wind farm from 2009.3 to 2010.2.
Output characteristics of Haeng-won wind farm is confirmed by analyzing the fluctuation rate of power for 1 min, 10 min and 30 min using the actual data. By using the moving average method, the optimal saturation time is found at 30 min.
So, the 2.45 MWh is fixed for the capacity of battery, and the rated power of inverter is determined 2 MW by the histogram of battery output requirement.
To control the stabilizing power, the output smoothing, SOC feedback and reference time variable control methods are used. Wind farm, batteries and inverter modeling are carried out by using PSCAD/EMTDC simulation program.
As a result, the proposed control methods show the excellent performance of the output power of wind farm.
