Electric vehicle orderly charging optimization method and system

Abstract

The invention discloses an electric vehicle orderly charging optimization method. A charging optimization system adopted by the charging optimization method comprises a processing module, a communication module, an information acquisition module and a power selection module, the information acquisition module and the power selection module are respectively connected with the processing module through the communication module, and the information acquisition module and the power selection module are respectively connected with an electric vehicle. According to the method, an optimization modelis established, minimization of the peak-valley difference of the power of the cell transformer is taken as an optimization target to construct an objective function, the rated power of the transformer is not exceeded as a constraint condition, and the charging time of the electric vehicle is solved by adopting a Morse-shell abrupt change genetic algorithm, so that the optimal access time of eachelectric vehicle is obtained. The charging load of each electric automobile is reasonably arranged through an intelligent algorithm, and the charging requirements of a large number of electric automobile users are met under the condition that the existing capacity of the transformer is not changed; the peak-valley difference of the output power of the transformer is effectively reduced, and the operation risk of a power grid is reduced.

Description

technical field [0001] The invention belongs to the field of charging optimization, and in particular relates to an orderly charging optimization method and system for an electric vehicle. Background technique [0002] Energy crisis and environmental pollution are two major problems faced by mankind at present. With the depletion of non-renewable energy and the continuous deterioration of the environment, electric vehicles are gaining unprecedented development opportunities with their advantages in energy saving and environmental protection, and become the direction of new energy. research hotspot. As a relatively large load in the future power system, the randomness and intermittent nature of electric vehicles connecting to the power grid will greatly increase the complexity of power system operation. In the future, residential areas will become one of the main places for charging electric vehicles, but there are certain difficulties in the transformation of charging facil...

Problems solved by technology

As a relatively large load in the future power system, the randomness and intermittent nature of electric vehicles connecting to the power grid will greatly increase the complexity of power system operation

In the future, residential areas will become one of the main places for charging electric vehicles, but there are certain difficulties in the transformation of charging facilities in the community

If a large number of electric vehicles are connected to the power grid without order, it will cause a great burden on the transformers in the current community, especially during peak power load periods, connecting a large number of electric vehicles will lead to peak load curve peaks, which is not conducive to the safety of transformers Stability and Economic Operation
