摘要
为了平滑风力发电功率的波动,常常在风电场中配置一定容量的储能装置,这样能够有效地抑制风力发电的间歇性和波动性.本文考虑储能系统的过度充放电对其使用寿命产生的不利影响,在充放电能力及充放电强度的双约束条件下,建立了基于二维云模型的储能控制系统,可以实时修正储能装置的充放电功率值.不仅抑制了风电功率的波动性,提高了功率输出的稳定性,而且使储能装置的荷电状态维持在一定范围内,避免了过度充放电,延长了储能装置的使用时间.最后运用MATLAB/Simulink软件对基于二维云模型的储能控制系统进行仿真,验证了该方法的正确性.
Wind power has the characteristics of intermittence and volatility.With certain capacity of energy storage devices,wind power volatility can be smoothed effectively.This paper,considering the damage to the energy storage system service life caused by the excessive charging and deep discharging,proposes a two-dimension cloud model control strategy for the storage system,under the double constrain conditions of the capability and intensity to charge and discharge.The strategy,adjusting the power reference value of energy storage system in real time,improves the stability of wind power output,and extends the energy storage system service life.Finally,the result of simulation in MATLAB/ Simulink shows the correctness and effectiveness of the cloud model control strategy.
