Sizing of Energy Storage for Wind PowerApplications

[摘要] The biggest weakness of wind power energy is the lack of exact predictability on its generation. Perhaps even if other energy sources can be saved by using wind energy, the short term power variation must be secured by a conventional plant. The variations in the output of a large wind farm results in many integration issues. The uncertainty in the output of a large wind plant can be overcome by using fast acting dispatchable sources. The goal is to reach the smallest possible difference between actual wind power and forecasted wind power. In this paper a model, which optimizes the wind power energy by battery based energy storage system with the help of conventional and intelligent controllers, has been developed. This paper presents controlling methodologies for a battery based energy storage system in conjunction with PID and Fuzzy logic controller. The results may show that choosing of proper controller along with battery based energy storage system will give effective control over wind power. In order to overcome the drawbacks of the wind power, the use of energy storage as power buffer has investigated.
