【摘要】：为风电场增加储能系统是平抑风电输出功率波动的有效措施之一。首先,通过对风电场出力进行频率分析,提出采用超级电容搭配蓄电池的混合储能方案平抑风电出力波动中的主要分量,并给出了一种混合储能系统模糊滑模控制策略,采用模糊控制器消除滑模控制器的高频抖振现象。然后,在RTLAB平台上搭建风电混合储能系统仿真模型。通过分析控制系统在扰动作用下的阶跃响应,验证了模糊滑模控制器的高抗扰性能。最后,仿真计算了采用模糊滑模控制策略前后储能设备的出力情况和荷电状态,进一步验证了该控制策略对风电出力平抑和提高系统抗扰性能的作用。
[Abstract]:Increasing the energy storage system for wind farm is one of the effective measures to stabilize the fluctuation of wind power output.Firstly, by analyzing the frequency of wind farm output, a hybrid energy storage scheme with super capacitor and battery is proposed to stabilize the main components of wind power output fluctuation, and a fuzzy sliding mode control strategy for hybrid energy storage system is presented.The high frequency buffeting phenomenon of sliding mode controller is eliminated by fuzzy controller.Then, the simulation model of wind power hybrid energy storage system is built on RTLAB platform.By analyzing the step response of the control system under the disturbance, the high immunity performance of the fuzzy sliding mode controller is verified.Finally, the output force and the charge state of the energy storage equipment before and after the fuzzy sliding mode control strategy are simulated and calculated, which further verifies the effect of the control strategy on balancing the wind power output and improving the disturbance immunity performance of the system.
