Furthermore, the four-quadrant operation for power converter systems ensures battery energy storage systems constantly control reactive power nearly independent of the energy stored. Again, it is worth noting that voltage support occurs locally because reactive power cannot be transferred over longer distances [ 188, 189 ].

In a power system, when extreme events occur, such as ice storm, large scale blackouts may be unavoidable. Such small probability but high risk events have huge impact on power systems. Most resilience research in power systems only considers faults on the physical side, which would lead to overly idealistic results. This paper proposes a two
