风储联合系统并网时对储能系统影响的研究
摘要
风能是目前国内外应用较为广泛的一种绿色可再生能源，近几年我国风电产
业的发展十分迅速。然后，越来越多的风力发电系统建并网，风力发电产生的电
能受外界因素影响较大，具有一定的随机性和波动性，给并网后的电力系统稳定
性带了巨大的影响。然后建立风力发电厂的储能系统是改善此种情况的最好的解
决办法。所以，风电储能控制系统在当下的发展前景十分好，控制策略、储能容
量及储能联合系统成为新一代的我们研究的方向。
由于国内人民生活水平的提高，科技不断地进步，控制不断地完善，导致不
可再生能源消耗严重，甚至殆尽，从而促使可再生能源成为行业的主导。风力发
电成为现阶段一处亮丽的风景线，由于其拥有成熟的开发技术，成本相对较小，
几乎无污染的优势，使得在新能源发电行业具有很高的前景，成为世界各国关注
的焦点。同时，因为风向可变性、随机性以及不可控制性较强，风力发电并网对
电压稳定性及电性能影响很大。风力发电行业不断革新，并网的数量越来越大。
因此新一代的我们要认真去钻研风力发电并网的影响。
随着储能系统研发成本的增加，使用周期缩短等各方面的短板，通常增加储
能装置来解决风力发电厂功率平滑控制工程，因此，给储能系统带来了巨大的挑
战目标。本次设计主要参考实际风力发电的事例，对风储联合系统中针对控制逻
辑进行设计开发，重点设计讨论关于双馈风力发电厂的储能系统输出波动较大的
现象，同时利用功率平滑滤波的控制策略对并网的无功功率进行补偿控制。

Abstract
Wind energy is a kind of green renewable energy widely used at home and
abroad.Then, more and more wind power generation systems are built and connected
to the grid. The electricity generated by wind power generation is greatly affected by
external factors and has certain randomness and volatility, which has a great impact on
the stability of the power system after being connected to the grid.The best way to
improve the situation is to build energy storage systems for wind farms.Therefore, in
recent years, the equipment, capacity configuration and joint operation control of wind
farm energy storage devices have become the focus of research and application
demonstration.
Due to the improvement of people's living standard, continuous progress of
science and technology, and continuous improvement of control, the consumption of
non-renewable energy is serious or even exhausted, thus promoting the renewable
energy to become the leading industry.Wind power generation has become a beautiful
scenery at the present stage. Due to its advantages of mature development technology,
relatively small cost and almost no pollution, it has a high prospect in the new energy
power generation industry and has become the focus of attention in the world.At the
same time, due to the strong wind direction variability, randomness and non-
controllability, grid connection of wind power generation has a great impact on voltage
stability and electrical performance.The wind power industry continues to innovate and
is increasingly connected to the grid.Therefore, the new generation of us should
seriously study the impact of wind power grid connection.
With the increase of energy storage system research and development costs,
shortened use cycle and other aspects of shortcomings, energy storage devices are
usually added to solve the wind farm power smooth control engineering, so it brings a
huge challenge to the energy storage system.This design mainly refers to the actual case
of wind power generation, designs and develops the control logic in the wind storage
joint system, focuses on the design and discusses the phenomenon of large output
fluctuation of the energy storage system in doubly-fed wind farm, and compensates the
reactive power connected to the grid by using the control strategy of power smoothing

and filtering.
