Power distribution network toughness improvement strategy based on environmental data prediction

Abstract

The invention relates to a power distribution network toughness improvement strategy based on environmental data prediction. Comprehensive environment data prediction analysis is carried out on the operation condition of a power distribution network and vulnerable links of the power distribution network are predicted, so that the early warning capability of disaster risks is improved; a power distribution network vulnerability prediction model based on environmental data pre-judgment is established, and the fault rate prediction level is improved; a power distribution network fault bearing capacity evaluation method based on environmental data is provided, and a power distribution network fault bearing capacity evaluation method is provided; the influence of ice disaster on the toughness of a power distribution network is reflected by using the change of system performance, and a power distribution network toughness evaluation model is established; the invention aims at implementing planning and scheduling measures for improving the toughness of a power distribution network in a catastrophe defense stage and a post-disaster recovery stage, and further provides a power distribution network toughness improvement strategy under environmental data pre-judgment. According to the invention, the toughness of a power distribution network is comprehensively improved in a disaster process and a post-disaster process through coordination and cooperation of active defense before a fault occurs and fault recovery after disaster.

Description

technical field [0001] The invention belongs to the technical field of operation control of electric power systems, and in particular relates to a distribution network toughness improvement strategy based on environmental data prediction. Background technique [0002] As a key link that directly serves users, the normal operation of the distribution network under extreme weather conditions is of great significance to protecting people's production and life, resisting disasters, and promoting social development. The disaster response capability of the distribution network has thus been widely recognized. s concern. On this basis, the distribution network introduces the concept of resilience to evaluate the ability of the distribution network to reduce the loss caused by faults and restore the normal power supply state as soon as possible under extreme weather conditions. In order to avoid the occurrence of large-scale power outages caused by extreme weather disasters, it is ...
