中文摘要：

随着风力发电系统装机容量的不断提升，风电占所在电网的比例也在逐步增加。由于风的高度随机波动性和间歇性，使得大容量的风电接入电网会对电力供需平衡、电力系统的安全、以及电能质量带来严峻挑战。为此，以我国浙江沿海地区的一个大型风力发电场连续3个月的运行数据为基础，根据不同风电场和储能系统的容量配比关系进行仿真分析，借助储能装置来抑制风电系统固有的波动，使风电这种间歇性、波动性很强的可再生能源变得“可控、可调”，使电网对这种最接近规模化发展的能源调度变为可能，提出了一种配置大规模储能系统的方案，初步优化了储能系统的容量。对设计大型风力发电场的储能系统进行了初步的探讨。可为相应的大型风电场建设储能系统提供一定的借鉴。

英文摘要：

The proportion of wind power in the grid increases rapidly as the capacity of wind farm increases. Wind power generation is not stable and cannot supply constant electrical output, which challenges the attempt to in tegrate large scale wind power scheme into grids. According to one year statistical data, we put forward a design scheme and a control method for the energy storage system in a large-scale wind farm in Zhejiang province. To maintain feasible grid operation, energy supply and demand must be kept in balance at all times. Finally, we optimized the capacity of energy storage system in large scale wind farm.
