Research on power distribution of battery clusters of electrochemical energy storage system in the frequency regulation process

Abstract

In recent years, a large number of electrochemical energy storage projects have gradually emerged and capability of battery is also becoming central issue for research. The battery control strategy directly affects the response to AGC (Automatic Generation Control). If the control is improper, it is easy to cause the remaining power of each battery cluster unbalanced and influence the battery life. This article mainly focuses on the research on the distribution of power commands from the battery management system, and proposes a power distribution method. The method was put into practice in an energy storage project which got good results.
