The Research On Hierarchical Time-extended Petri Net Model For Power Transmission System Restoration

Power transmission system restoration,which is a nonlinear multi-constrained multi-objective optimization problem,needs to consider a large number of discrete control variables and constraints.This paper attempts to set up preliminary mathematical model of power transmission system to search the optimal program.This paper set up a power transmission system recovery model,and definite the steady-state electrical constraints;set up the transmission system recovery expert rules indicator system and through analytic hierarchy process to resume the action GRA,provides a search algorithm based on expert rules;on the foundation of transmission system recovery model,provides a search algorithm based on time-extended Petri Net;diseuss the security check content and a few details need to pay attention to the problem.
