Holistic Control Approach for the Grid-Connected Converter of a Battery Energy Storage System

Autor: Ciro Nunez, Nancy Visairo-Cruz, Alberto Arellanes, Dante Mora, Juan Segundo

Publikováno v: IEEE Access, Vol 8, Pp 216844-216855 (2020)

This paper introduces a holistic control approach applied to a grid-connected converter of a Battery Energy Storage System (BESS). The BESS is mainly used for power peak shaving, frequency supporting, and islanded operation mode which implies multipl
