摘　　要：飞轮储能具有功率密度高、转换效率高和低污染等优点而逐渐受到国内外学者的重视,但是由于飞轮储能单位投资容量小,不适宜应对长时间变化负荷而未被大范围推广。蓄电池储能虽然能量密度大,但是频繁地充放电会缩短其使用寿命。飞轮储能和蓄电池储能结合的混合储能系统能够优势互补。以补偿风电场功率为目标,建立飞轮储能和蓄电池储能混合的储能系统模型,制定以飞轮储能优先充放电的控制策略,并对风电补偿功率进行滤波。飞轮和蓄电池分别响应高频和低频功率,以减少蓄电池储能的充放电次数,延长其使用寿命。通过仿真,证明了系统模型的正确性和控制策略的有效性。Flywheel energy storage has gradually attracted the attention of scholars at home and abroad due to its high power density,high conversion efficiency and low pollution.However,compared with other energy storage methods,it has not been widely promoted due to the smaller capacity under the same investment and unsuitable for dealing with long-term load changes.Battery storage has high energy density,but frequent charging and discharging will shorten its service life.Therefore,the hybrid energy storage system combining flywheel energy storage with battery energy storage can complement each other.In order to compensate the wind farm power,a hybrid energy storage system model of flywheel energy storage and battery energy storage was established,and the control strategy of priority charge and discharge of flywheel energy storage was formulated,and the wind power compensation power was filtered in this paper.Flywheel and battery are responsible for high-frequency and low-frequency power respectively to reduce the charge and discharge times of battery energy storage and prolong its service life.The simulation verifies the correctness of the system model and the effectiveness of the control strategy.
