Abstract

The invention discloses an electric vehicle cluster dispatching method. The method comprises the steps of S1, establishing a mathematical model of a single electric vehicle according to an energy boundary concept; S2, performing cluster division on the electric vehicles according to the time when the single electric vehicle is accessed to the power system; and S3, based on an improved firefly algorithm, solving the electric vehicle load cooperative dispatching model. The mathematical model of the electric vehicle load is accurately established, the problem of dimensionality disasters generatedunder large-scale electric vehicle access is solved, the operation cost of a power grid is reduced, and the peak-valley difference of the power grid is reduced.

Description

technical field [0001] The invention relates to the technical field of power grid operation and control, in particular to an electric vehicle cluster scheduling method. Background technique [0002] With its environmental protection and energy-saving features, electric vehicles have become an inevitable trend in the development of the world's automobile industry. The charging or discharging of electric vehicles on the grid will bring many impacts to the grid. On the one hand, its aggregated load will increase the burden on the grid. Here comes the challenge. Therefore, it is of great significance to accurately establish a mathematical model of the electric vehicle load and to schedule the charging and discharging of electric vehicles in an orderly manner. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a method for electric vehicle cluster dispatching, so as to avoid the curse of dimensionality and reduce the o...
