Abstract:With the development of economy,the influence of China is growing sharply,and the world - class political,cultural and sport activities are carried out in China frequently,which leads to more strict requirement of power guarantee. In order to satisfy these requirements,a novel multi - level coordinated dispatching pattern is proposed based on power guarantee of significant activities through process optimization,integration of technology and human resources and multi - level joint dispatching. This novel pattern is able to guarantee the good power supply and quick response. The proposed pattern is verified by G20 summit and the thirteenth session of the student sports meeting.
