Embodiment 2

[0141] This embodiment is implemented on the basis of Embodiment 1, and the same content will not be repeated here. The difference is specifically the solution process of the immune algorithm, as follows:

[0142] S1: Import the topology information, business information, risk degree of each node in the business single path set, the risk degree of each link, the network risk degree of the business single path set, the network load degree and the network balance degree of the power communication network, Set algorithm parameters: clone parent population number, mutation probability, population size number and maximum iteration number n max , generating n 0 Antibodies are used as the initial population O(n), the global vaccine is injected, and the number of iterations is set to n=0.

[0143] S2: Calculate the affinity of each antibody q, and sort the antibodies in O(n) in descending order by affinity, and extract the local vaccine. Select the first m in O(n) l Antibodies cons...

Embodiment 3

[0167] This embodiment is implemented on the basis of Embodiment 1 and Embodiment 2, specifically with figure 2 The network topology shown is the experimental object. It can be seen from the figure that there are 11 nodes and 15 links in the network. Set the parameters in the immune algorithm to clone the parent population to 30, the mutation probability to 0.1, the population size to 100, and the maximum evolutionary generation n max for 500. Set the failure probability of the node and the failure probability of the link They are:

Abstract

The invention discloses a method and a system for risk balancing for a power communication network. The method comprises steps: node information, link information between adjacent nodes and service information in the power communication network are acquired; according to the acquired information, multiple service paths corresponding to each service are determined; a service path is randomly selected from the multiple service paths respectively to form a service single path set; according to the acquired information and the at least one service single path set, the risk degree of each node and the risk degree of each link are determined; according to the risk degree of each node and the risk degree of each link, the risk degree of the network is determined; according to the at least one service single path set and the service information, a network load degree is determined; and according to the network risk degree and the network load degree, a preset service path optimization model is adopted to obtain an optimization path for each service. The risk and the load of the power communication network can be comprehensively considered, and the risk of the power communication network can be effectively reduced.

Description

technical field [0001] The invention relates to the field of risk equalization of electric power communication networks, in particular to a method and system for risk equalization of electric power communication networks. Background technique [0002] With the rapid development of the smart grid, the power system presents the characteristics of increasingly frequent collaborative communication among many subsystems, and a large number of services need to be deployed in the network. Different from traditional telecommunication services, power communication services are closely related to power system production, dispatching and control. Power communication security risks are strictly graded, specifying the type, quantity, and degree of impact of each risk level, and restricting high-level security risks. The occurrence of communication risks is an important goal of the power communication sector. Therefore, how to deploy services to the network in a balanced manner is the fo...
