The rapid development of modern power systems with tightly coupled cyber-physical interactions has also increased the risks of cyber-physical cascading faults. Low earth orbit (LEO) satellite internet

as a novel communication medium

offers unique advantages

including low susceptibility to ground- based disasters

wide coverage

low latency

and high bandwidth

providing a new pathway for enhancing the resilience of cyber-physical power systems. This study

from the perspective of LEO satellite internet supporting post- disaster restoration

proposes a cyber-physical collaborative restoration framework and model for power distribution networks with satellite-terrestrial communications. This framework elucidates the coupling relationships between power grids and communication networks in terms of energy supply

information exchange

and temporal recovery under integrated satellite-terrestrial communications. It further characterizes the cyber-physical collaborative restoration process of power distribution networks

considering constraints such as satellite communication terminal deployment

satellite communication link capacity

and satellite communication duration. To reduce computational complexity

this paper employs linearization techniques and feasible region reduction methods. The effectiveness of the proposed model and method are verified through the case study of the 10-node information network-IEEE 33-node power distribution network system.
