With the construction of ultra-high voltage(UHV)AC/DC interconnected power grid

the advancement of new energy and the deepening of electricity market reform

significant changes have taken place in the operation of power grid in China

which makes higher requirements on the dispatching and control functions. Based on the integrated distribution and concentration deployment scheme of application functions

this paper gives an overview of the new features of the application function

i. e.

global

rapid and accurate

analyzes the technological support to realize such application functions

and points out the urgency of promotion basic work such as power grid model

operation data and management rules.
