dispatch operation management, as shown in Figure 3. They
are vertically deployed in the control centers of national-,
regional-, provincial-, district-, and county-level power grids,
as shown in Figure 4, to realize the coordination among
multilevel control centers and, at the same time, form distributed backup control centers shared among them. Thus, a

cybersecurity defense system was established to cope with
all kinds of electrical accidents and cybersecurity threats.
The overall goal of the sgos is to implement horizontal integration and vertical penetration. Through horizontal
integration, specialized departments in a control center can
share eMs functions and data. Through vertical penetration,
