It is small that charging power planned assignment and Mineral resource are carried out to all charging stations；
It is described according to charge requirement Service EfficiencyWherein: PMFor power grid
The maximum charge power for certain following period that company issues, ΩEFor charging station set；PiFor the charge requirement of i-th of charging station；
It is described to carry out charging power planned assignment according to charge requirement Service Efficiency size and Mineral resource refers to:Wherein:It is weighed by i-th of charging station according to the initial charge that charge requirement Service Efficiency distributes.It is filled when always
When electricity demanding power is less than charging nargin, charge requirement Service Efficiency β is 1, what the charging that charging station obtains at this time was weighed and declared
Demand is identical, only weighs to charging and carries out planned assignment；When total charge requirement power is greater than charging nargin, charge requirement Service Efficiency is small
In 1, when influencing electric power netting safe running, each charging station charges according to the respective ratio planned assignment for submitting charge requirement and weighs, and opens
It opens two way auction and the trade market P2P excitation charging station carries out autonomous market to charging power and distributes rationally；
The guarantee fund is for two way auction, in the trade market P2P, the payment and settlement for the power that charges between charging station；For handing over
The easy period finally completes a business transaction period charging expense to grid company payment；For completing a business transaction the period, the limitation of charging station charge power size
Guarantee；If charging station charge power is weighed higher than charging obtained, guarantee fund is deducted；The guarantee fund Di=πt×Pi×Δt
× 2, in which: DiFor the guarantee fund that block chain is calculated, πtIt strikes a bargain for the standard that grid company is set when trading session starts
Electricity price, PiPeriod charge requirement is completed a business transaction for what charging station was submitted, Δ t is to complete a business transaction period duration, and whole day is divided into 48 herein
Period, therefore the duration should be 30 minutes；
The charging station carries out needing to meet during the deals match of charging power using two way auction and P2P pairing mechanism:
Wherein: Pi,jTransaction is weighed in charging between i-th of charging station and j-th of charging station
Amount, Pi,j> 0, which represents i-th of charging station, buys charging power, Pi,j< 0, which represents i-th of charging station, sells charging power；Pi,EIt is filled for i-th
The acquired total charging power within certain following period in power station；
The current charging powerWherein: Ωi SCarry out charging power transaction with i-th of charging station to be all
Charging station set.As block chain is according to total charge requirement and the initially allocated charging of current power distribution transformer capacity nargin
Power and charging station are weighed in the charging that acquisition was independently bought/sold to two way auction and P2P transactional stage.
