Abstract

The invention relates to a power grid safety evaluation method and device, computer equipment, a storage medium and a computer program product. According to the invention, the operation safety and stability of the power grid system can be improved. The method comprises the following steps: taking each device of a transformer substation as a node, mapping a connection relationship among the devices as an edge among the nodes, and calculating security risk class, security state class and attack loss class evaluation elements of each node to obtain a current local security measure; calculating a first global security metric according to all the current local security metrics and the associated edges thereof; calculating various evaluation elements of each divided area, and calculating comprehensive security measurement of each divided area according to the various elements of each divided area and the first global security measurement; and calculating various evaluation elements of the target power network, and carrying out overall fusion on the various elements of the target power network and the comprehensive security measurement of each divided region by using a volleyball super-match algorithm to obtain a network security evaluation total measurement of the target power network.

Description
