Abstract: Fast acting battery energy storage systems are able to swing power very quickly between maximum import and maximum export in less than 50ms based on operational experience of a 2MW energy storage system. However, this can result in nuisance tripping of the unit through the operation of the loss-of-mains protection (LoM). This paper looks at data captured during power swings of up to 4MW during typical operation and discusses the potential for nuisance tripping, and suggests potential settings for improved operation.
