摘要
重力储能是重要的储能方式之一,具有独特的短时暂态动力学特征,需要构建合理的系统结构和控制方法.提出了一种面向重力储能直流环节的多模式控制方法,从暂态能量控制角度,通过对重力储能系统的动力学分析和约束条件的划分,实现电池储能和重力储能的功率匹配.仿真验证表明,该控制方法能够在输入功率波动的情况下显著降低直流环节的电压抬升,合理分配重力储能系统内部的功率,提升重力储能系统的整体性能.
Abstract
Gravity energy storage is one of the important energy storage modes.However,due to its unique transient dynamic characteristics,it is necessary to construct a reasonable system topology and control method.In this paper,a multi-mode control method for the DC link of gravity energy storage is proposed.From the transient energy control perspective,the power match between battery energy storage and gravity energy storage is realized through dynamic analysis of the gravity energy storage system and delineation of the constraint conditions.The experimental results show that the proposed control method can significantly reduce the voltage rise of DC link in the case of input power fluctuation,reasonably allocate the power inside the gravity energy storage system,and improve the overall storage performance of the gravity energy storage system.
