The invention discloses a power
system insurance and supply
risk assessment method considering an
extreme weather typical meteorological year, and the method comprises the steps: 1, obtaining historical meteorological data of a target region, generating a typical meteorological year through employing a Sandia method, and improving the typical meteorological year through employing a quantile increment mapping method, and obtaining the
extreme weather typical meteorological year; 2, performing scene division on historical meteorological data in a typical meteorological year of
extreme weather by adopting a K-means clustering
algorithm, using an obtained clustering result to
train a denoising variation auto-
encoder model, generating a typical weather scene set and calculating the probability of a typical meteorological scene; 3, by taking the minimum
load shedding capacity and the minimum wind and light abandoning capacity of the power
system as targets, constructing a supply guarantee
operation model of the power
system; and 4, calculating an insurance supply
risk assessment index of the power system. According to the method, supply insurance
risk assessment is carried out on the typical meteorological year of the extreme weather, and supply insurance weak links of the novel power system with high
new energy permeability under the extreme weather are described by calculating supply insurance risk indexes under the typical scene of the extreme weather.
