摘要
在分析飞轮储能系统(FESS)、电池储能系统(BESS)、超级电容和超导磁储能系统(SMES)等多种储能技术基本工作原理的基础上,探讨了风力发电储能系统集总式和分布式的拓扑结构,分析了两类储能系统及其并网变流器的功率特性,比较了集总式和分布式储能系统在改善电网电压、减小频率偏差的能力优劣。基于dSPACE建立实验系统,实验结果表明两类储能系统在抑制风电功率波动、改善电能质量方面皆具有效性,与分布式储能系统相比,集总式储能系统可以实现更小的功率波动,但要求更高的变流器容量。
Integrating an energy storage system in a wind farm is an effective method to reduce wind power fluctuations. Various ESS technologies and configurations were proposed for this application, such as flywheel energy storage （FES）, battery energy storage system（BESS）, super-capacitor storage and superconducting magnetic energy storage（SMES）. The aggregated and distributed connection topologies of the ESS technologies were studied. The power ratings of the ESSs and their power electronic conveners were estimated. The abilities of the aggregated and distributed ESSs to improve local voltage and reduce system frequency deviations were evaluated and compared. The experimental results based on dSPACE have shown that the two ESS configurations have effective performance to suppress wind power fluctuations and improve the power quality. Compared to the distributed configuration, the need a higher convener power rating.
