V2G technology-based power distribution scheduling control method for electric vehicles

Abstract

The invention discloses a V2G technology-based power distribution scheduling control method for electric vehicles. According to the power distribution scheduling control method, besides that the influences of charge and discharge power of the electric vehicles are considered, the limiting factors of the capacity of a power distribution network, technical conditions of the electric vehicles and the like are also considered; the traffic factors of drive routes, charging/discharging access and the like of the electric vehicles are further considered; optimized charging and discharging scheduling strategies, for the electric vehicles, conforming to the reality are comprehensively determined; charging and discharging of the electric vehicles are controlled by a V2G system; and the power distribution scheduling control on the electric vehicles is achieved. The embodiment and related data show that according to the V2G technology-based power distribution scheduling control method for the electric vehicles, the negative effects on the system reliability due to the fact that the electric vehicles are accessed on a large scale can be effectively improved; the load utilization rate of the power distribution network is improved; the load peak and off-peak difference of the power distribution network is reduced; and improvement of power distribution scheduling economical efficiency of the electric vehicle and power distribution network operation economical efficiency is helped.

Description

technical field [0001] The present invention relates to the technical field of grid-connected electric vehicles and the technical field of economic dispatching of electric power resources, in particular to a V2G technology-based electric vehicle power distribution dispatching control method. Background technique [0002] With the increasing demand and consumption of fossil fuels, energy shortage and environmental pollution have become problems that countries all over the world need to solve urgently. Electric vehicles (Electric Vehicle, EV) rely on electric power to drive, low noise, high energy efficiency, and "zero pollution". Compared with traditional fuel vehicles, they can more directly solve problems such as energy dependence, exhaust emissions, and environmental pollution. Its large-scale application is regarded as one of the most effective ways to alleviate energy shortage, air pollution and realize low-carbon economy. [0003] Commonly used electric vehicles in Chi...

Problems solved by technology

[0006] Most of the above research results on the charging load of electric vehicles use statistical modeling methods to simulate the random characteristics of the charging load and establish the charging load model of electric vehicles. There are relatively few studies on the equivalent power of electric vehicle discharge, let alone Considering the impact of factors such as traffic factors and discharge access locations during driving of electric vehicles, there is no effective guidance for practical applications
