Abstract

An embodiment of the present invention provides an emergency recovery method for a thermoelectric coupling system under an extreme cold disaster, including: based on the source-side index, grid-side index and load-side index, define a comprehensive evaluation index for the post-disaster recovery capability of the thermoelectric coupling system, and then determine the post-disaster recovery of the thermoelectric coupling system The optimization target model in the recovery process; define the emergency recovery constraints of the optimization target model; solve the optimization target model to obtain the optimal recovery strategy for the thermoelectric coupling system after the disaster, and use the optimal recovery strategy to restore the thermoelectric coupling system after the disaster. The embodiment of the present invention defines the evaluation index of the post-disaster recovery ability of the thermoelectric coupling system, and establishes the optimization objective function and corresponding constraint conditions for the disaster emergency recovery of the thermoelectric coupling system, and obtains the optimal post-disaster recovery strategy of the thermoelectric coupling system, realizing the maximization of the system The strategy scheme with the fastest restoration ability and system performance recovery rate.

Description

An emergency recovery method of thermoelectric coupling system under extreme cold disaster technical field The present invention relates to the technical field of power grids, in particular to a method for emergency recovery of thermoelectric coupling systems under a kind of extreme cold disaster. Law. Background technique [0002] The recovery strategy in the post-disaster phase refers to recovering the power outage and heat outage areas in the system after the natural disaster is over. Energy supply, and the process of repairing faulty lines of the system by dispatching human emergency repair resources to restore the normal operation of the system. Always run. At present, related research has proposed many strategies for post-disaster recovery, including building an emergency rescue system, using Distributed generator sets such as micro-grids, manpower emergency repairs, topology reconstruction, etc., these strategies are used in the traditional grid-side system pe...
