Smoothing Control of Wind Power Output using Short-term Average Value
Abstract
Energy storage system (ESS) attached wind farm can reduce the wind power fluctuation and increase the grid stability. However, the operation of ESS can cause a losses and negative effect on lifecycle of batteries. From
this point, this thesis proposes wind power smoothing control by using short-term mean value. In this case, the operation of ESS will be determined by wind power fluctuation rate during one minute. It means that the ESS
will not operate at small fluctuation of wind power which does not affect grid stability.
In order to verify the effectiveness of proposed method, this thesis will compare the wind power smoothing control by low pass filter, the ramp rate control and the proposed method by using Matlab program. And also, to analyze the effect of power quality, simulations will be carried out with the wind power data measured by 15,000 kW wind farm located in Jeju Island.
