Figure 3. The proposed state transfer model.

directly used to the theoretical basis of smart distribution

network risk warning. For the practical application, the

risk prediction analysis and causes mining before the

incident provides technical support for smart distribution

network from passive defense to active defense, which

promotes the security of electricity supply, improve the

reliability, and reduces the impact of the grid accident

and hazards, and has great practical significance on

operation, planning and designing of the power system

and the development of society as well.
