Abstract

The invention relates to a dynamic demand response method under the condition of large-scale electric vehicle access, which includes the following steps: (1) making big data clustering analysis according to the information obtained from an electric vehicle electricity consumption information big data platform of electric vehicle charging and battery swapping under the condition of large-scale access to form a load characteristic curve based on electric vehicle charging and battery swapping; (2) establishing an electric vehicle dynamic demand response model of large-scale access; and (3) solving the model by a particle swarm optimization algorithm to obtain a demand response strategy of power supply enterprises. The household electric vehicle orderly charging strategy under multiple objectives of the invention well takes into account the balance between user expenditure reduction and system load fluctuation reduction, has good economic benefits for both the user side and the grid side,and can achieve mutual benefit and win-win between the user and the grid.

Description

technical field [0001] The invention belongs to the technical field of electric power demand response, relates to electric vehicle access, in particular to a dynamic demand response method under the condition of large-scale electric vehicle access. Background technique [0002] Nowadays, the problems of environmental pollution and energy shortage are becoming increasingly serious, and the main reason for these problems is that the existing energy sources are mainly non-renewable fossil energy, so it is necessary to develop and utilize new energy while reducing the use of fossil energy . [0003] Electric vehicles are favored by the market for their clean and environmentally friendly features. In 2016, global electric vehicle sales reached 773,600 units, a year-on-year increase of 42%. As of the end of December 2016, there were more than 2 million new energy vehicles on the road, of which 61% were pure electric vehicles and 39% were plug-in hybrid vehicles. Sales of new en...
