Abstract: Described are systems and methods for black-starting an electrical grid, comprising disconnecting an energy farm from the grid at a first location, said first location being located between the electrical grid and the energy storage with the associated converter, providing a synchronous condenser, energizing the AC export cable using said energy storage and the associated converter, energizing at least one part of the energy farm electrical infrastructure via said AC export cable using said energy storage and the associated converter, re-establishing energy supply to said energy farm electrical infrastructure by said electric generators, energizing said synchronous condenser, and reconnecting the energy farm to said electrical grid at said first location.

Abstract: Described are methods and systems comprising providing an energy hub having an electrical infrastructure; providing a number of generators of electrical energy and a plurality of consumers of electrical energy connectable to and disconnectable from said electrical infrastructure, the plurality of consumers comprising at least one critical consumer of electrical energy and at least one non-critical consumer of electrical energy; disconnecting the energy hub from the grid; supplying said electrical infrastructure with electrical energy from at least some generators among said number of said generators of electrical energy; using said electrical energy by means of at least some consumers of said plurality of consumers; monitoring at least voltage and frequency of said electrical energy in said electrical infrastructure; and selectively disconnecting and/or reconnecting one or more of said non-critical consumers of electrical energy.
