Firefly algorithm based method for determining position and capacity of electric automobile charging station

Abstract

The invention discloses a firefly algorithm based method for determining the position and the capacity of an electric automobile charging station. The method is characterized by comprising the following steps: 1, setting a strategy combination determined by the position and the capacity of the charging station according to actual conditions in a planning area; 2, performing searching optimization on a target function by use of a firefly algorithm to find out a minimum value of the target function so as to determine an optimal position and capacity strategy in the strategy combination, wherein the target function is a power distribution network rack planning model associated with a rack construction investment cost and a power distribution network operation loss cost; and 3, verifying the optimal position and capacity strategy in a constraint condition, if the strategy satisfies the constraint condition, determining the position and the capacity of the charging station, if the strategy does not satisfy the constraint condition, deleting the optimal position and capacity strategy from the strategy combination, and carrying out step two again. The firefly algorithm can be used for solving a power distribution network plan of the electric automobile charging station, the algorithm employs fewer parameters, the operation is simple, the realization is easy, and the method has the advantage of good global searching optimization.

Description

technical field [0001] The invention relates to the field of power distribution, in particular to a method for determining the location and capacity of an electric vehicle charging station. Background technique [0002] With the increasingly severe environment and energy situation, zero-emission and low-noise electric vehicles have become the development trend of the automobile industry. With the increase in the number of electric vehicles, electric vehicle charging stations are an effective supporting facility for electric vehicles, and the demand for the construction of charging stations is becoming more and more urgent. Compared with now, the number of electric vehicle charging stations must be more and more, and the capacity must be larger and larger. As a part of the grid, the electric vehicle charging station will inevitably affect the planning of the distribution network, such as the increase of grid investment and network loss, the overload of lines and transformers...
