Network slice management method and management system of smart power grid

The invention provides a network slice management method and management system for a smart power grid, and the method comprises the steps: obtaining a work order submitted by a user, and the work order comprises a demand parameter value of a network slice of a target power grid service; if a power grid service matched with the type of the target power grid service exists in a first power grid service preset with a service model and/or a second power grid service corresponding to an existing network slice, according to a parameter value of the network slice corresponding to the power grid service matched with the type and the demand parameter value, determining the type of the target power grid service according to the parameter value of the network slice corresponding to the power grid service matched with the type and the demand parameter value. Determining a target parameter value of a network slice of the target power grid service; and sending the target parameter value to operator equipment to order the n
