摘要/Abstract

摘要：

储能系统与风电场联合运行，不但可跟踪风电场计划出力，还可参与电网的辅助服务。以风储联合运行的总收益最大为目标，考虑储能系统跟踪风电计划出力与参与电网二次调频服务，建立风储联合运行的优化模型。该模型重点考虑了计及不同荷电状态下的储能寿命损耗和储能参与调频时向上调频电量与向下调频电量的平衡。基于实际风电场运行数据设计算例并进行仿真分析，结果表明，考虑储能寿命损耗和储能调频电量水平，不仅可以合理衡量储能参与各项服务所带来的收益，还可以充分发挥储能的作用并提高风储联合的收益。

Abstract:

The joint operation of the energy storage system and the wind farm can not only track the wind power schedule output, but also participate in ancillary service of the power grid. In order to maximize the total profit of the optimization of wind storage joint operation, the optimal model of wind storage joint operation was established considering the wind energy storage system tracking wind power schedule output and participating in the secondary frequency modulation service of the power grid. The model took into account the energy storage life loss under different state of charge, and the up-frequency modulation power and down-frequency modulation power balance when energy storage participated in frequency modulation. Based on the actual wind farm operation data, an example was designed and the simulation was carried out. The results show that considering the energy storage life loss level not only measure the benefits of energy storage participating in various services, but also give full play to the role of energy storage and improve the benefits of wind storage joint operation.

Key words: energy storage system, wind power generator, tracking wind power schedule output, secondary frequency regulation
