Abstract

The invention discloses an electric vehicle orderly charging optimization scheduling method based on a Logic-Benders decomposition algorithm. The method comprises the following specific steps of firstly, constructing an electric vehicle charging mode selection main model based on mixed integer linear programming; secondly, based on constraint planning, constructing an electric vehicle charging time sequence optimization sub-model; and finally, carrying out iterative solution on the main sub-model by adopting a Logic-Benders decomposition algorithm. The method is advantaged in that on the premise of ensuring the charging demand of the user, the optimal economy of the electric vehicle charging scheduling system is realized through selection of the charging mode of the electric vehicle and optimization of the charging time sequence.

Description

technical field [0001] The invention relates to an optimal scheduling method for ordered charging of electric vehicles based on a Logic-Benders decomposition algorithm, and belongs to the technical field of ordered charging of electric vehicles. Background technique [0002] With the development of the electric vehicle industry and the promotion of related industrial policies, the number of electric vehicles is growing rapidly. The connection of a large number of electric vehicles to the power grid will lead to a surge in the load of the power grid in a short period of time, which will bring certain risks to the safe operation of the power grid. Therefore, the orderly charging strategy of electric vehicles is one of the current research hotspots. Its purpose is to use practical and effective economic or technical measures to guide and control the charging of electric vehicles on the premise of meeting the charging needs of electric vehicles, and to carry out the load curve a...
