Embodiment Construction

[0044] look up figure 1 , a low-voltage power line carrier dynamic routing method based on the firefly-ant colony algorithm, including:

[0045] Step 1, initialize the parameters of the firefly algorithm, including the maximum attractiveness β 0 , the step size factor δ, the attraction rate λ to light, and the maximum number of iterations TMax;

[0046] Step 2, there are N fireflies, and the position of each firefly corresponds to the α, β, ρ parameters in the ant colony algorithm; among them, ɑ is the information heuristic factor, indicating the relative importance of the trajectory; β indicates the relative importance of visibility ρ represents the volatilization coefficient of pheromone;

[0047] Step 3, there are K ants, which are divided into N groups, and each ant in each group corresponds to using the position of one firefly among the N fireflies as its parameter, and performs pheromone initialization on each routing path. In this embodiment , the pheromone is initia...

Abstract

The invention discloses a low-voltage power line carrier dynamic routing method based on firefly-ant colony algorithm. The method comprises the following steps of: step1, initializing parameters of afirefly algorithm; step2, taking each firefly position corresponding to each parameter in the ant colony algorithm; step3, taking a firefly position corresponding to each ant as a parameter thereof; step4, each ant performs an ant colony algorithm to obtain an optimal path; step5, judging the firefly position according to the optimal path of the current solution, adjust the firefly attraction andposition, and return to step 3; step6, when the firefly position converges, the parameter optimal solution of the ant colony algorithm is obtained, and the obtained path is the optimal path from the router to the electric meter J. According to the method, the convergence speed of the ant colony algorithm is fast, and the convergence path is optimal.

Description

technical field [0001] The invention relates to the technical field of low-voltage power line carrier dynamic routing, in particular to a low-voltage power line carrier dynamic routing method based on the firefly-ant colony algorithm. Background technique [0002] In recent years, many countries such as the United States, Japan, and Europe have successively launched research on smart grids, and my country also released the development rules for building a "strong smart grid" in 2009. To achieve the goal of "Strong Smart Grid", there are many technical obstacles to be resolved, and the low reliability of low-voltage power line carrier communication is the main obstacle restricting the current realization of Smart Grid. Due to the high noise, high attenuation, time-varying and other related characteristics of low-voltage power lines, the communication distance of power lines is shortened and the reliability is deteriorated. These problems are difficult to solve at the physical...
