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 power system communication, and particularly relates to a power communication network routing method for joint balance of load traffic and service risks. In terms of load traffic balancing, the link channel occupancy condition and the node traffic admission condition are considered in the power communication network routing method provided by the invention, and then a load weight function of the link is designed; in terms of service risk balancing, modelling is performed on the availability of an optical fiber link of a power communication network, and then a balancing strategy considering the service priority and the service risks that the link has carried is designed; and finally, a balancing factor is introduced to construct a link cost function that comprehensively considers the load and the risks so as to achieve the joint balance of the carrying capacity and the service risks. According to the power communication network routing method provided by the invention, the balancing factor can be adjusted according to the importance of the service, the network blocking rate and the service risks of the network can be reduced at the same time, the link load traffic and the risk value are balanced, and finally the network reaches the optimal 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 ...
