Composition and Test Method of the Emergency Control System for Battery Storage Power Station on Grid Side

When the transmission power of UHVDC line or provincial AC tie line drops sharply, the power storage station at the grid side is connected to the fine cutting system because of its fast power response characteristics, and it provides support for the safe and stable operation of the main network through the timely switching of the whole station operation mode. In this paper, the composition and operation principle of the battery storage power station on the grid side are analyzed comprehensively, and the emergency control system architecture, strategy and test method of the storage power station are analyzed in depth, hoping to provide useful reference for relevant practitioners.
