摘要
该文为压缩空气 超级电容混合储能系统设计了负荷跟踪的互补控制结构及控制器。压缩空气储能蓄电量大、无污染,但其系统惯性大,难以满足用户快速变化的需求。通过设计压缩空气 超级电容混合储能系统的互补控制,充分发挥压缩空气储能装置的电力续航能力和超级电容的反应快速性能。考虑压缩空气压力变化对膨胀机发电侧的影响,采用自适应控制器确保系统的跟踪性能。仿真结果表明,电网需求突变时,采用互补控制的多尺度储能系统具有快速响应能力并消除储气罐压力变化带来的影响。
The complementary control structure and controller for load tracking are designed for compressed air super ca pacitor hybrid energy storage system.The compressed air stored energy has large storage capacity and no pollution,but its sys tem inertia is large,which is difficult to meet rapidly changing needs of users.The complementary control of compressed air su per capacitor hybrid energy storage system is designed to bring the power endurance ability of the compressed air energy storage device and the fast response performance of the super capacitor into full play.In consideration of the influence of pressure change of the compressed air on the power generation of the expander,an adaptive controller is used to ensure the tracking per formance of the system.The simulation results show that when the power grid demand changes suddenly,the multi scale energy storage system with complementary control has fast response capability and can eliminate the influence of pressure change in the gasholder.
