Abstract

The invention provides a design method for a topological structure of a power transmission network based on a multi-agent genetic algorithm and aims at solving the technical problem of poor robustness when the power transmission network resists attack or disturbance due to weak deep search capability and easiness in falling into the local optimum in an existing design method for the topological structure of the power transmission network. The design method comprises the following realization steps: setting parameters of the multi-agent genetic algorithm; initializing a population of the multi-agent genetic algorithm; carrying out neighborhood competition on the initialized population; carrying out neighborhood intersection on the neighborhood competition; mutating neighborhood intersection species; carrying out population local search on a mutated population to generate a local search population serving as a topological structure output of the power transmission network. According to the design method provided by the invention, in the design process of the topological structure of the power transmission network, a multi-agent genetic algorithm framework is adopted, a neighborhood competition operator, a neighborhood intersection operator, a mutation operator and a local search operator are designed, and the topological structure with high robustness of the power transmission network is designed out.

Description

technical field [0001] The invention belongs to the field of physical technology, and relates to a method for designing a topology structure of an electric power transportation network, in particular to a method for designing a topology structure of an electric power transportation network based on a multi-agent genetic algorithm. When attacked or disturbed, the function of the power transportation network can be kept intact to the greatest extent, and at the same time, it can effectively resist the attacked or disturbed. Background technique [0002] In the power transportation system, power stations, substations, etc. can be abstracted into complex network nodes, and transmission lines can be regarded as connection edges, then the power transportation system can be abstracted into a complex network model, called the power transportation network. The topology design of the power transportation network is to adjust the topology of the power transportation network while keepi...
