电池储能技术在可再生能源电站并网中的应用综述

与常规能源电站不同，可再生能源电站的出力具有间歇性和波动性，其大规模并网将对电网产生一系列的负面影响。文章在现有研究成果的基础上，总结了主流电池技术的特性，以及电池储能系统BESS在可再生能源电站并网中的应用现状，并对其应用前景和进一步的研究工作进行了展望。研究表明：电池储能系统可显著改善可再生能源电力固有的间歇性，实现对可再生能源电力的有效调度，且能平滑可再生能源发电系统的功率波动，降低其对电能质量和电网稳定运行的不利影响。因此，BESS具有广阔的应用前景，应继续加强对降低电池成本以及大型电池储能系统的集成、运行技术等的相关研究。

Application of Battery Energy Storage Technology in the Grld Network of the Renewable Energy Power Plants

Different form conventional energy plant, the output of renewable energy power plant output is intermittent and volatile, the incorporating of which will cause a series of negative effects on national grid network. On the basis of existing research results, the author summarizes the features of mainstream battery technology and the application status of battery energy storage system （BESS） in renewable energy power plants, and also puts forward the prospect of its application and further research work. Studies have shown that BESS can significantly improve renewable energy power inherent intermittence to achieve an effective scheduling, and can smooth fluctuations in renewable energy power generation system, reducing its stable operation of power quality and power grid adverse effects. Thus, this technology has a broad application prospect, and more efforts should be put to reduce battery costs and conduct more research on the integration and operation technology of large BESS in future.
