Abstract

A power distribution network pre-disaster toughness improvement method considering typhoon time sequence and information physics cooperative regulation comprises the following steps: by analyzing the time sequence and uncertainty of a typhoon disaster, constructing a DCPS element vulnerability model under the influence of a strong wind-rainstorm dual disaster-inducing factor; generating a typical DPCS disaster scene set based on a DCPS element vulnerability model in combination with historical typhoon disaster data; the dynamic response of the power distribution network in the typhoon disaster process is incorporated into a pre-disaster toughness improvement framework by considering information physical cooperative regulation; and establishing a pre-disaster toughness improvement model, and performing solution in the generated typical DPCS disaster scene set to obtain an optimal pre-disaster toughness improvement scheme. According to the method, by considering the typhoon disaster time sequence and the system dynamic response, the static hypothesis limitation that the typhoon disaster is simplified into an instantaneous uniform impact event in the traditional research is broken through, and a toughness improvement scheme better meeting the actual requirements of the system is formulated.
