The invention discloses a
natural disaster risk relieving method and device for a power
system, and the method comprises the steps: constructing an hour-level composite
cascade event set generation module which is used for generating hour-
level data sets in various
natural disaster scenes, capturing the
cascade effects of different disasters, and generating a
data set; data support is provided for power
system risk influence quantification and risk mitigation module strategy generation; a distributed resource evaluation module is constructed and used for evaluating the availability and power generation potential of distributed resources in the third-level region, and the power generation potential of the distributed resources in various
natural disaster periods is analyzed in combination with weather and disaster factors; a natural disaster influence module is constructed, the influence of various natural disasters on the power
system is simulated based on the hour-level composite
cascade event set, the damage degree of the disasters on loads, power generation facilities,
power transmission and distribution lines and the like is analyzed, and the risk influence on the power system is quantified; and constructing a risk relief module, for an area with risk influence, formulating a disaster emergency scheme based on a three-level cooperation mechanism, and based on the power generation potential of the distributed
resource assessment module, by scheduling various distributed resources, repairing the
power grid, adjusting the load and reducing the disaster influence, ensuring rapid
recovery and stable operation of the
power grid.
