Example Embodiment

[0066] Examples:

[0067] 1. Vehicle travel time and space model based on travel chain.

[0068] The travel chain is to describe the time and space change process of residents in a certain time and space to complete a series of activities. This process includes the traveler's time, space, activity purpose, transportation mode and other information. Daily travel behavior of electric vehicle users includes other information such as driving destination, departure time, driving distance, and parking time. By investigating and analyzing the travel behavior of electric vehicles, we can get the travel chain of electric vehicles in one day. Considering that since electric vehicles are currently in the trial operation and gradual promotion stage, reliable historical data related to the travel characteristics of electric vehicle users are relatively lacking, so this article assumes that electric vehicles have travel characteristics similar to traditional fuel vehicles.

Abstract

The invention belongs to the technical field of electric power systems and particularly relates to a method for electric vehicle load prediction based on an efficiency maximization principle. First a space-time distribution model of electric vehicles is established based on a trip chain, information such as initial departure time, driving destination, driving distance and stopping time is analyzed, and charging space-time distribution of the electric vehicles is obtained. Charging stations most favorable for users are selected based on the efficiency maximization principle to charge the electric vehicles, and finally space-time distribution of electric vehicle charging loads is given. On the basis of the fact that the electric vehicle load prediction by previous scholars is only confined to the time level and the regional level, the method for electric vehicle load prediction based on the efficiency maximization principle is provided, and the load prediction can be detailed to the charging stations.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to an electric vehicle load forecasting method based on the principle of efficiency maximization. Background technique [0002] As the basic industry of the national economy, the energy industry is not only a necessary prerequisite for ensuring national strategic security, but also an important guarantee for achieving sustainable economic development. With the expansion of economic scale, the demand for traditional energy such as oil continues to increase, and more and more carbon content is emitted into the atmosphere, which makes the pressure of energy shortage and ecological environment deterioration increasing. With its advantages of energy saving and environmental protection, electric vehicles have become an effective way to solve the shortage of energy resources and serious air pollution. [0003] The electric vehicle industry has been listed as one of the s...
