Based on the business demand of the regional and county dispatching centers

an analysis is made of the problems of the high network security requirement

fast development of dispatching control data

big differences between regional and county dispatching centers

lack of full auxiliary emergency decision-making and whatnot. A summary is made of technical solution in support of WAN safe interconnection between regional and county dispatching and control systems

adaptability to network bandwidth for regional and county dispatching centers

meeting different on-demand real-time monitoring demands of regional and county dispatching centers

improvement of large data processing capability

the comprehensive anti-maloperation capability

and the full auxiliary emergency decision-making. Finally

a look-ahead is presented for future technology development in promoting the smart dispatching and control system in the regional grid.This work is supported by National High Technology Research and Development Program of China (863 Program) (No. 2011AA05A118)
