Abstract

The present invention relates to a multi-dimensional comprehensive index-based power grid vulnerability evaluation method and belongs to the power system intelligent analysis and control technical field. The multi-dimensional comprehensive index-based power grid vulnerability evaluation method is characterized in that multi-dimensional comprehensive indexes for power grid vulnerability evaluation are built; and power grid vulnerability is evaluated from three aspects, namely, equipment vulnerability evaluation, network vulnerability evaluation and operation vulnerability evaluation. Adjustment and control operation personnel can realize the key monitoring of power grid vulnerable equipment or power grid vulnerable weak links through the visualized power flow diagram of a local dispatching control system, and therefore, the adjustment and control operation personnel can be facilitated to timely process vulnerability factors that may affect the safety of a power grid.

Description

technical field [0001] The invention relates to the technical field of power system intelligent analysis and control, in particular to a method for assessing the vulnerability of a power grid based on multi-dimensional comprehensive indicators. Background technique [0002] The increasing scale of the power grid and the large-scale interconnection of the power grid are a trend in the development of the modern power system. The large-scale power grid has realized a wide range of resource optimization, improved the reliability of power supply, and achieved significant economic benefits. New challenges are coming. Uncertainty factors in the network increase, hidden faults are difficult to detect, and the mechanism of accident development is more complicated. Partial faults may stimulate weak links in the power grid, causing cascading faults, expanding the scope of faults, and even threatening the entire network. Safety. In order to ensure the safe operation of the large power ...
