Summary: | The invention provides a load outage loss risk assessment method and system for a tough power distribution network. The method comprises the following steps: constructing an expansion probability graph model; acquiring a power grid topology file and a power grid line fault probability table of the tough power distribution network; solving the power probability of the load node at each moment in the target time period; and converting the power-on probability of the load node at each moment in the target time period into the power-off probability of the load node at each moment in the target time period, and calculating to obtain a load outage loss risk. According to the ductile power distribution network load outage loss risk assessment method and system provided by the invention, the load outage loss risk is calculated by constructing the extended probability graph model and utilizing the extended probability graph model, the whole process mainly relates to a nonlinear equation set solving process, and the ca |
