Reducing Variability in Wind Power Generation by Combining Slope Control with SOC Feedback

This paper presents a method to minimize fluctuations in wind power generation. The aim is to reduce power variation in a wind energy conversion system using a control scheme based on ramp events. This, along with a smoothing control system that utilizes a battery energy storage system (BESS), helps to reduce power fluctuations. To test the method, a wind farm model consisting of 26 wind turbines, each with a capacity of 2 MW, situated along a coastal profile (52 MW of installed power), is used as a case study. The results illustrate the effectiveness of the proposed method compared to the original system performance, demonstrating a significant improvement in power generation stability, as well as a reduction of more than 45% in the originally sized BESS capacity.
