How to consider the impact of natural disaster when implementing network differential planning has become an urgent issue. Based on a rationality analysis of the anti-disaster mode,an anti-disaster transmission network expansion planning method considering the constraints of natural disaster scenario is put forward,and the relevant guideline of transmission expansion planning for the anti-disaster mode is identified. According to the characteristic analysis of the modeling,by integrating the embedded N-1 and disjunctive constraints,a high-efficiency model for anti-disaster transmission network expansion planning is designed for lean decision-making of anti-disaster investment. Using the proposed method,a Garver 6-bus system numerical example and a network differential planning instance of a certain provincial grid are given to prove the validity of the proposed model. While providing a scientific basis of network differential planning,the model proposed is of instrumental reference to improving the lean management level and perfecting the relevant regulations of network expansion planning.
