A smart charging electric vehicle energy network connection dispatching method and system

Abstract

The present invention relates to a method and system for intelligent charging electric vehicle energy network connection dispatching, under the background that the charging pile has the automatic charging capability of being able to automatically connect to and disconnect from the electric vehicle charging interface to switch charging target vehicles among a certain number of vehicles, Considering the objective constraints such as electric vehicle charging and discharging power limit, battery state of charge and distribution network capacity, and integrating the interests of electric vehicle users, power grid and charging pile operators, a method for determining the charging of each vehicle in a multi-vehicle scenario is established. Priority and strategy for charging and discharging power. The dispatching method proposed by the present invention faces the current problems of shortage of charging piles and disorderly charging of electric vehicles. It can realize orderly charging of electric vehicles when there are too many vehicles and few piles, and rationally utilize charging resources. While meeting the travel needs of car owners, reducing The power grid fluctuates, and provides a pricing plan that is beneficial to the operator's profitability, increasing the enthusiasm of enterprises to promote in the market.

Description

technical field [0001] The invention relates to the field of energy network connection of electric vehicles, in particular to a scheduling method and system for energy network connection of intelligent charging electric vehicles. Background technique [0002] Today, global warming and energy shortage have become two major crises affecting the sustainable development of human society. Due to the rapid growth of global energy consumption, it is foreseeable that fossil energy will be exhausted in the near future. Since the liquid fuel consumed by internal combustion engines and the greenhouse gases emitted in the transportation field are the main factors of energy depletion and global warming respectively, reducing emissions and consumption in the transportation field is considered to be an important way to reduce or even solve the crisis. Electric vehicles have high hopes for their advantages such as the ability to convert clean and renewable resource electric energy into pow...
