Embodiment 1

[0059] Embodiment one: as attached figure 1 as shown,

[0060] A power communication network routing method for joint balancing of load flow and business risk for realizing balanced operation of the power communication network, comprising the following steps:

[0061] Step 1: Input the network topology G=(V, E, D, W) corresponding to the power communication network in the control system of the power communication network, where V represents the node set in the power communication network, and E represents the chain in the power communication network D represents the link distance matrix of the power communication network, W represents the link capacity matrix of the power communication network, |V| and |E| represent the total number of nodes and the total number of links in the power communication network, respectively. Then initialize the load weight and risk weight of each link in the network topology G to be 1, and calculate the initial routing weight of each link accordin...

Abstract

The invention belongs to the technical field of electric power system communication, and in particular relates to a power communication network routing method for joint balancing of load flow and business risk. In terms of load and flow balancing, the present invention considers the link channel occupancy and node traffic acceptance, and then designs the load weight function of the link; in terms of business risk balancing, the availability of optical fiber links in the power communication network is modeled , and then design a balance strategy that considers the business priority and the business risk carried by the link; finally, introduces the balance factor to construct the link cost function that comprehensively considers the load and risk, so as to realize the joint balance of the carrying capacity and business risk. The invention can adjust the balancing factor according to the importance of the business, can reduce the blocking rate and business risk of the network at the same time, balance the link load flow and the risk value, and finally make the network achieve the best performance.

Description

technical field [0001] The invention belongs to the technical field of electric power system communication, and in particular relates to a power communication network routing method for joint balancing of load flow and business risk. Background technique [0002] With the gradual deployment and advancement of the Energy Internet, the frequency of interaction between the source network and the load will accelerate, the production and management services carried by the power communication network will increase, and new applications such as high-definition video distribution and cloud services will be in the ascendant. The increase in power grid information services has led to an increase in the demand for bandwidth, but the available power communication network resources are limited, and the core usage of some backbone optical cables is close to saturation. There are local bottlenecks in the network, which cannot meet the needs of new communication circuit needs. The gradual ...
