摘要
随着电力系统中风电接入比例的不断提高,风电接入对电力系统的影响日益凸显。风电的一个典型特点是风能具有随机性和间歇性,这会导致风电本身出力的波动性,进而对电力系统的频率造成影响。本文从风电本身的波动性及风力发电设备的特殊性两方面,对已有研究进行综述,阐述风电接入对电力系统频率的影响。在此基础上,对风机参与系统调频(主要是一次调频和二次调频)的具体方法进行了综述。
Renewable energy,especially wind energy,has developed rapidly in recent years,which will substitute the conventional fossil fuel energy.The impacts of wind power on power system become more and more evident with the increasing percentage of wind power in power systems.The stochastic and intermittent properties of wind energy cause the wind power fluctuation,which further impact system frequency.In this paper,the current research on the impacts of wind power on power systems are reviewed from following two aspects,the fluctuation of wind power and the particularity of equipments of wind generation.Based on this,the detail approaches for regulating system frequency,mainly primary and secondary frequency regulation,are concluded.
