Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0044] A risk level acquisition method provided by the embodiment of this application is applied to but not limited to the acquisition of the risk level of the power grid revenue in the current cycle. It should be noted that the cycle is generally one year, that is, this method is specifically used for each The acquisition of power grid income risk. This method is based on a pre-built index system and a matter-element extension model to obtain the current risk level of the grid inco...

Abstract

The embodiment of the invention provides a risk level collection method, a device, equipment and a readable storage medium. The method comprises the steps: obtaining the value of each preset index, and obtaining the correlation degree between each index and each risk level according to the value of each index, a node domain and a classical domain at each risk level; and obtaining a grade evaluation result according to the evaluation parameters. The indexes comprise an index for representing power flow complexity and an index for representing line loss, so that the indexes represent characteristics of multiple dimensions during operation of the power system, namely, values of the indexes can represent the operation state of the power system, and the classic domain and the time domain are data collected from historical data; therefore, the association degree between each index and each risk level can be objectively indicated based on the association degree obtained by the classic domain and the time domain, and the association degree between the operation state of the current power grid and each risk level is further indicated, so that the level evaluation result obtained by the method according to the indexes of multiple dimensions has objectivity and accuracy.

Description

technical field [0001] The present application relates to the technical field of risk level acquisition, and in particular to a risk level acquisition method, device, device and readable storage medium. Background technique [0002] The determination of the risk level of the power grid income has positive significance for the operation of the power system. When the power system is running, under the excitation of the power supply potential, the current or power flows from the power supply to the load through each component of the system and is distributed throughout the power grid. trend. Due to the complexity and unobservability of the power flow, it often leads to the grid line loss that cannot be accurately measured. The study of a large amount of historical objective data found that power flow and power grid line loss are important evaluation indicators for the operation of the power grid system, and are also key influencing factors for the risk prediction of power grid...
