重力储能直流环节电池多模式控制方法
Multi-mode Control Method of Gravity Energy Storage DC Link Battery
摘要
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.关键词
