Abstract

The invention discloses a method for orderly charging an electric vehicle under a gridding time-of-use electricity price, and the method comprises the following steps: dividing a power distribution network into a plurality of load blocks in detail based on the spatial layout, load characteristics, functional region division and the like of a target region, and forming a power distribution network region grid; performing historical load arrangement on each grid based on the power distribution network area grid, and realizing accurate load prediction of each grid based on corresponding historical load data; reasonably formulating the time-of-use electricity price of the electric vehicle under each grid based on a grid load prediction result; and guiding the user to charge orderly by using a demand response mechanism based on the established electric vehicle gridding time-of-use electricity price. According to the invention, the electric vehicle can be guided to be charged orderly while the electricity price of the electric vehicle can be formulated, so that the effects of peak load shifting, reasonable source configuration optimization, power daily load curve optimization and load peak-valley difference reduction of a power grid are achieved, and a guarantee is provided for safe operation of the power grid.

Description

technical field [0001] The invention relates to charging technology, in particular to an orderly charging method for electric vehicles under grid-based time-of-use electricity prices. Background technique [0002] At present, electric vehicles are widely supported and promoted due to their advantages of cleanness, environmental protection, high efficiency and energy saving. increase. Moreover, the disorderly charging of a large number of electric vehicles will further increase the peak load of the power grid, increase the peak-to-valley difference of load, and cause a decline in power quality, affecting the safe and stable operation of the power grid. Contents of the invention [0003] The main purpose of the present invention is to provide an orderly charging method for electric vehicles under grid-based time-of-use electricity prices, using electricity prices to guide electric vehicle users to charge orderly, so as to realize electric vehicles participating in the proce...
