An optimal energy storage capacity calculation method for 100MW wind farm

Abstract

In the recent years, wind energy generation has been focused as a clean and inexhaustible energy and penetration level have increased throughout the world. But the wind power generation is not stable and cannot supply constant electrical output. Since the wind power output depends on wind, as a natural source, the electrical output always fluctuates due to the weather, site conditions and other possible factors. This variability brings with it challenges when one attempts to integrate large-scale wind power scheme into grids, since to maintain satisfactory grid operation, energy supply and demand must remain in balance at all time. Inserting energy storage system into large scale wind farm to eliminate the fluctuation become a solution for developing large scale renewable energy system connected with grid.
