摘要
储能系统在削峰填谷、平抑功率波动、保障微型电网的稳定运行方面有着非常重要的作用,它是微型电网的关键组成部分。并联式混合储能技术采用简单成熟的双向直流变换器、性能互补的超级电容和蓄电池以及高可靠性并联技术,在充分保障蓄电池使用寿命的基础上,研究了混合储能系统的3种工作模式和切换方式,提高了微网运行的稳定性和可靠性。
Energy storage system is the key component of micro-grid structure,which plays an important role in both cutting and restraining the power fluctuation and guaranteeing the stable operation of the micro-grid.Parallel hybrid energy storage technology could fully guarantee the service life of the accumulator by means of simple mature bidirectional DC/DC converter,the complementation of super capacitor and storage battery and parallel technology with high reliability.Based on which the paper studies three operating modes and mode switching,which has been proven to improve the stability and reliability of the micro-grid function.
