Space-air-ground integrated power grid slice architecture and resource optimization method thereof

The invention discloses a space-air-ground integrated power grid slice architecture and a resource optimization method thereof, and belongs to the technical field of electric power. The power grid slice architecture comprises an electric power service sensing layer, a network arrangement layer, a network slice layer and an infrastructure and virtualization layer; the power service sensing layer receives service request information and transmits the service request information to the network arrangement layer; the network arrangement layer enables slice design in the network slice layer according to the service request information by managing and coordinating a specified admission control and resource allocation strategy; the network slice layer defines slices as multi-dimensional resource information sets of different network segments and performs corresponding transverse and longitudinal slices, the transverse slices are slices of power grid resources of different spaces, and the longitudinal slices are slic
