In view of the problems of system heterogeneity

low efficiency in model interaction

low automation level of interactive process existing in the construction mode of power grid model center

a construction method for power grid model center is put forward based on the particle size of power plant/substation. Through a study of power grid model interaction technology and on-demand model proxy service mechanism with the particle size of power plant/substation

the model fusion

interaction efficiency

security and the model partition maintenance problems are solved in the construction of model center between dispatching systems. With an actual power grid as an example

it is verified that the proposed construction method is capable of improving the interaction efficiency

model quality

and automation maintenance level in the building of model center

as well as solving the problems of the heterogeneous scheduling system to be integrated into the model center.
