Abstract

The invention proposes a power restoration method based on network equivalence and parallelization, which includes the steps: off-line calculating, pre-storing of data, establishing of a power grid's initial topology structure, generating of an offline equivalent source point table of a first-level feeder X, parallel computing of real-time support capabilities and restoring of power. The method is suitable for solving the problem of power restoration in smart distribution networks with various types of adjustable flexible sources. In the face of varying degrees of power loss, the method of the present invention can quickly find safe and reliable power restoration programs so that various types of support resources in the smart distribution networks can be utilized reasonably and effectively. In addition, the economy of the operating programs is also considered. Therefore, an optimal program can be selected for the quick restoration of power.

Description

technical field [0001] The invention relates to the field of power system operation control, in particular to a power supply recovery method based on network equivalence and parallelization. technical background [0002] The power supply restoration of the distribution network is the process of rapidly restoring power supply to non-fault outage areas through network reconfiguration when the power grid fails. To solve this problem, it is necessary to consider various constraints related to the safe and stable operation of the network, as well as a variety of optimization objectives: to support as many power-loss loads as possible and to maximize the economics of power supply restoration. Therefore, power supply restoration is a multi-constraint, multi-objective combinatorial optimization problem, which has been paid attention to for a long time. [0003] Among the various commonly used power supply restoration methods, the heuristic search method is most commonly used for re...
