| 摘要: |
| 风电功率波动率是风电并网考核的重要内容之一，采用蓄电池储能装置是平滑风能波动最常用的方案。为提高储能设备的使用寿命，提出一种蓄电池充放电控制策略，在最小容量配置下能保持蓄电池荷电量（SOC）水平，同时实现对风电功率的滤波。MATLAB仿真结果表明所提控制策略可以在满足风功率波动指标的基础上取得良好的SOC控制效果，且实际并网储能系统的模拟测试验证了该策略的可行性和有效性。 |

| Abstract: |
| Wind power fluctuation rate is a key performance indicator of its grid-connection and the battery energy storage device is widely used to smooth the wind power fluctuation. For prolonging the device lifetime，a strategy of battery charge／discharge control is proposed to maintain the SOC（State Of Charge） level of the battery under the minimum capacity configuration while filter the wind power fluctuation. Simulative results of MATLAB show that，a better SOC control effect is achieved while the wind power fluctuation rate satisfied. And test on practical integrated BESS（Battery Energy Storage System） verifies the feasibility and effectiveness of the proposed strategy. |
