This paper presents the application of a superconducting fault current limiter (SFCL) to energy storage for protection in a distribution power system. An energy storage system (ESS) adds a number of benefits for ps, it has a drawback for ground fault protection. These are inter related with a neutral grounding method for an interconnecting transformer used to connect the energy storage and power systems. There are several types of connections used to inter-connect with a power grid. In a grid-side grounded y-delta winding connection is prevalent for interconnection generation to the utility system, as well as for all central-station generation. However, there is a direction on the negative side of the fault current created in case of a ground fault in the distribution power lines. The ground fault will generally coordinated power system protection and subsequently disconnect the energy storage from the grid.
