Immune algorithm-based siting planning method of electric power communication network access points

Abstract

The invention discloses an immune algorithm-based siting planning method of electric power communication network access points. The method is characterized in that the method comprises steps of 1: determining an access point siting network model; 2: establishing an access point siting mathematic model including cost, reliability, time delays and N-1 principle constraints; 3: defining related concepts of antibodies and antigens in the immune algorithm so as to allow the related concepts to satisfy requirements on access point siting; 4: setting parameters of the immune algorithm and initializing antibody populations; 5: cloning, varying and selecting the antibody populations so as to form a new generation population; 6: judging iteration finishing conditions, and if the iteration finishing conditions are met, finishing iteration, or else continuing the step; and 7: obtaining an optimal access point siting scheme. According to the invention, by comprehensively considering economic construction cost, network reliability, N-1 principles and network time delay constraints, reliable and effective communication of an electric power communication network can be ensured.

Description

technical field [0001] The invention relates to the field of data gateways of electric power communication networks, in particular to queuing theory constructing network delay constraints and access point planning strategies based on immune algorithms. Background technique [0002] With the wide application of smart grid, the communication infrastructure is gradually developing in the direction of digitalization, real-time, scalability, manageability, safety, reliability and low cost, and the power communication network is an important communication infrastructure to ensure the safe and effective operation of smart grid. Therefore, the power communication network can effectively monitor and collect the communication data between the power grid and users, and transmit these information data to the upper-level business system through each data access point, and deploy a large number of intelligent power terminals in the power grid. Since the access point is a bridge between th...

Problems solved by technology

[0003] At present, Haidine et al. studied the optimal location of the access point in the low-voltage power grid, considering the network construction cost and network reliability, but did not consider the N-1 principle, which made the disaster tolerance capacity of the network poor

Silvia et al. used the N-1 principle to verify and analyze the impact of link failures on network reliability when studying access point planning, but did not use it as a constraint factor for planning

In addition, none of the above studies considered the network delay constraints
