Systems and methods for extending black-start availability using energy storage systems can be provided. In one example implementation, a method includes detecting, by one or more controllers, a disconnection of the power system from a power grid; obtaining, by the one or more controllers, data indicative of the amount of energy present in a first energy storage system; obtaining, by the one or more controllers, data indicative of an amount of energy associated with powering one or more loads coupled to the power system; and determining, by the one or more controllers, to activate the auxiliary power source based at least in part on the amount of energy present in the first energy storage system and the amount of energy associated with powering the one or more loads.

Extending black-start availability using energy storage systems

Systems and methods for regulating a short circuit current associated with an energy storage system are provided. In one embodiment, an energy storage system can include an energy storage device and a switching power supply coupled to the energy storage device. The energy storage system can further include one or more cables configured to couple the energy storage device to the switching power supply, and a magnetic framework positioned proximate the one or more cables. The magnetic framework can include one or more magnetic structures and can span at least a portion of the length of the cables. The one or more cables are positioned in a physical arrangement that, in conjunction with the magnetic framework, facilitates a selected inductance between the cables.

Cable arrangement of an energy storage system

Power converters that can allow for the transfer of DC power between a ground-referenced bus and a floating system are provided. In one embodiment, the power converter includes a ground-referenced DC bus associated with a DC voltage. The power converter further includes a first switching element, a second switching element, and a third switching element coupled in series between the ground-referenced DC bus and a ground reference. The power converter further includes a floating system associated with a floating DC voltage. The floating system can include a first terminal coupled to a first node between the first switching element and the second switching element. The floating system can further include a second terminal coupled to a second node between the second switching element and the third switching element.
