Power dispatching method considering new energy output uncertainty and cascading failure risk

The invention belongs to the technical field of dispatching of a power system, and provides a power dispatching method considering new energy output uncertainty and cascading failure risk, which comprises the following steps: determining relevant parameters of each distribution period by using a moment estimation method; obtaining a wind power and photovoltaic output uncertainty set to describe new energy output uncertainty; evaluating the Poisson intensity under various disasters by using a moment estimation method; for different types of disasters, setting a future risk pre-control scheduling period and a risk probability threshold so as to determine the cascading failure Poisson probability distribution of the disasters in the scheduling time from the occurrence of the disasters, and obtaining the maximum number of failures reaching the threshold in the scheduling period; and constructing a two-stage robust optimization model with the goal of minimizing the operation cost of the system under the condition
