Optimal Strategy of Anti-icing Disaster of Grid Based on PMRM

The loss caused by icing disaster is related to icing disaster's occurrence probability.This paper introduces risk function into objective function of risk decision-making model by using partitioned multi-objective risk method(PMRM).And then it studies anti-icing disaster strategy of different regions.Example results show that this method is reasonable and effective and it overcomes the shortcomings of traditional methods,which provides scientific basis for anti-icing strategy.
