Power grid disaster recovery control model modeling method based on CIM standard

Abstract

Provided is a power grid disaster recovery control model modeling method based on the CIM standard. The method comprises the steps of unit start-up optimization model building, network reconstruction optimized mathematical model building and load recovery optimized mathematical model building, and the directions of a unit start-up optimization model, a network reconstruction optimized mathematical model and a load recovery optimized mathematical model are adopted. A power grid analysis model for fault recovery treatment is constructed, an improved model minimum spanning tree fault recovery treatment method for online application is provided, on the basis of modeling a complex regional power grid, the search range and growing direction of a minimum tree are dynamically adjusted according to the current attribute and real-time path weight of a subsystem in the model, and therefore fast search for an optimal recovery path is achieved. The overall disaster recovery complexity is technologically avoided, and the overall system obtained after disaster recovery is made to be in the state better than that before the disaster recovery, and the continuity of service stability is guaranteed.

Description

technical field [0001] The invention relates to electric power information management technology, in particular to a method for modeling a power grid disaster recovery control model based on the CIM standard. Background technique [0002] The article "Development, Status and Prospects of Power Grid Fault Restoration" mentioned that after the power grid fails, how to quickly and accurately restore the power supply in the faulty outage area is of great significance to meet the power supply needs of users and reduce power outage losses. The development process of fault recovery at home and abroad is reviewed, and the relevant mathematical models of fault recovery and the constraints that need to be satisfied in the process of recovery are outlined. Summarizes the commonly used fault recovery methods at present, such as mathematical optimization method, expert system, fuzzy algorithm, artificial neural network, intelligent optimization algorithm, Petri net technology, multi-agen...

Problems solved by technology

In the current research on disaster recovery, it is basically outside the study of a single link and a single operating procedure, and there is not much research on the overall disaster recovery technology model, and the connection of various process links in the disaster recovery stage In terms of processing and processing, no detailed and in-depth research has been carried out, so that there is a certain lack of coordination in the recovery of the entire disaster environment, and the recovery of the entire disaster cannot be realized according to a tool algorithm mechanism
