Abstract

The present invention is applicable to the field of electric vehicle charging, and provides an orderly charging method, device and terminal equipment for electric vehicles, including: acquiring charging station information and exchanges at multiple times of substations in the area where each charging station is located according to the demand location for electric vehicle charging Bus power; establish a power distribution optimization model to obtain the number of vehicles that can be accommodated in the charging station, and determine the initial electricity price of each charging station according to the dynamic electricity price model and the number of vehicles that can be accommodated in the charging station; Determine the optimal charging station based on the decision model and the initial electricity price of each charging station, and determine the corresponding electricity price according to the optimal charging station; judge whether the changes in the two electricity prices meet the preset price difference condition, and if so, determine that the current electric vehicle is in the preferred charging station Charge. The invention transfers the charging load space of the electric vehicle, promotes the consumption of photovoltaic power generation by the grid, reduces the charging cost of the electric vehicle owner, and realizes orderly charging.

Description

technical field [0001] The invention belongs to the field of electric vehicle charging, and in particular relates to an electric vehicle orderly charging method, device and terminal equipment. Background technique [0002] With the continuous deterioration of the environment around the world, traditional energy sources are decreasing day by day, and more and more people pay attention to the concept of green and environmentally friendly life. Therefore, the electric vehicle industry has developed rapidly, and solar energy has also been widely researched and used. But at present, due to the constraints of the urban road network structure and user travel habits, the layout of charging stations does not match the charging needs of users. A large number of electric vehicles are charged in disorder, causing obvious peaks and valleys in the AC bus power of substations. The peak period of electricity has a great impact on the power grid. At the same time, due to the influence of geo...
