摘要
随着风力发电大规模入网,其随机性、波动性和间歇性特征对电力系统调频、调峰等有功平衡手段及电压稳定的影响越来越严重。储能系统能够在一定程度上控制风场的输出功率,平抑风电功率波动,改善风机低电压穿越能力,甚至为系统提供辅助服务,是从风场侧提高系统对风电的接纳能力的可行解决方案之一。作者在简要的介绍了风场储能技术应用现状的基础上,重点针对储能型风场内蓄电池储能系统的设计方案、容量优化及控制策略的研究现状及关键问题进行综述及探讨。
With the integration of large scale wind power into electrical network,concerns over frequency regulation,peak load shaving and voltage stability are growing due to fluctuation,randomness and intermittency of wind power.Energy storage systems（ESS） could ease such issues from the generation side（wind farm） to a certain extent through controlling wind power plant output,improving the low voltage ride through capability,and even providing ancillary services to the power system,therefore enabling an increased penetration of wind power.This paper provides a review on the application of ESS technologies in generation（wind farm） side,with emphases on the design,optimization of ESS capacity and control strategy of ESS.Key scientific and technological issues associated with these aspects are also outlined.
