Abstract

The invention discloses an electric vehicle energy efficiency power plant characteristic parameter evaluation method considering user participation degrees; the method comprises the following steps: aiming at an electric vehicle using a distributed charging pile to carry out normal low speed charging, and building a monomer electric vehicle model integrally considering active and reactive power response ability respectively from the power angle and energy accumulation angle; aiming at an electric vehicle of the working purpose, and building an electric vehicle participation degree response model; finally building an electric vehicle energy efficiency power plant model aiming at an electric vehicle cluster on the basis of the monomer electric vehicle model and the electric vehicle participation degree response model, wherein the electric vehicle energy efficiency power plant model comprises an electric vehicle energy efficiency power plant response ability parameter, an electric vehicle energy efficiency power plant energy storage ability parameter and an electric vehicle energy efficiency power plant price response cost parameter. The method can provide key model parameters for the electric vehicle energy efficiency power plant participating the power market transaction mechanism.

Description

technical field [0001] The invention relates to a modeling method for an electric vehicle energy efficiency power plant, in particular to a modeling method for an electric vehicle energy efficiency power plant considering user participation. Background technique [0002] The large-scale popularization of electric vehicles (Electric Vehicle, EV) is an important way to realize the development of low-carbon transportation, and has attracted widespread attention worldwide. With the large-scale access of electric vehicles, some weak links of the power grid may be overwhelmed [1,2]. [0003] With the development of power electronics technology, modern control and communication technology, electric vehicles can be regarded as a kind of electric energy storage system under the control of Vehicle-to-Grid (V2G). Electric vehicles can change their charging modes (such as disorderly charging and intelligent charging, etc.) to realize the transformation of charging power on a time scale...
