Power dispatching communication network node importance identification and evaluation method

Abstract

The invention discloses a power dispatching communication network node importance identification and evaluation method, which comprises the steps of S1, dividing a node importance identification criterion of a power dispatching communication network into three levels, namely a topology layer, a flow layer and a service layer; S2, respectively evaluating the importance of the power dispatching communication network nodes in the topology layer, the flow layer and the service layer; S3, performing normalization processing on importance indexes of the power dispatching communication network nodesin each layer; S4, obtaining importance evaluation of the nodes through a preference learning multi-attribute decision algorithm; or obtaining the importance measurement value of the communication network node through direct summation calculation. According to the evaluation method, importance evaluation of the nodes in the network topology level, the flow level and the service level is comprehensively considered, the importance degree of the nodes in the power dispatching communication network can be accurately and reasonably identified and evaluated, and the evaluation method has great significance in improving the network robustness, reducing the network failure risk and improving safe and reliable operation of a power grid.

Description

technical field [0001] The invention relates to the technical field of power dispatching communication, in particular to a method for identifying and evaluating the importance of nodes in a power dispatching communication network. Background technique [0002] The power dispatching communication network covers every control center and substation of the power grid. It is an important infrastructure that carries the measurement and control data of the power system and ensures the safe and stable operation of the power system. With the continuous expansion of the scale of the power grid system, the scale and complexity of the power dispatching communication network also increase, and at the same time, it brings problems such as the increase of the vulnerability of the network itself. Once the key nodes in the dispatching communication network fail or are maliciously controlled, resulting in a large-scale interruption of the communication channel of the power grid, it will cut o...

Problems solved by technology

However, the identification of node importance in most communication networks only considers the physical position of the node in the network topology, etc., and does not have various control, protection, measurement, Therefore, it is urgent to establish a set of comprehensive node importance identification and evaluation methods that match the power business and grid structure.
