Description
Technical field
The invention belongs to urban transportation technical fields, and in particular to PHEV power exchange system based on alliance's block chain and
Its method of commerce.
Background technique
Energy internet is the Innovation Networks for serving energy production, transport, storage and distribution management, it integrates fortune
With advanced electronic technology, information technology and intelligent management technology, the interconnection of distributed energy node is got up, to realize energy
Two-way flow, peer switch are shared with balanced.As the mobile storage facility of distributed energy, plug-in hybrid-power automobile
(plug-in hybrid electric vehicle, PHEV) is an important component of energy internet, it is by spirit
Mobility living is possibly realized vehicle to the power exchange of power grid (Vehicle-to-Grid, V2G), is constantly increased with reply
Energy requirement and extremely unbalanced Energy distribution.Traditional electric car is compared, the more energy efficient environmental protection of PHEV, many countries are all positive
Development deployment, intensive and huge charging infrastructure also constantly build up landing, this produces green traffic and smart city construction
Significant impact is given birth to.
With being continuously increased for PHEV quantity, their daily charging behavior will inevitably impact on energy internet,
And reasonable management of charging and discharging helps to improve the stability of smart grid, and the equilibrium of supply and demand of maintenance energy market.So
The Intelligent Energy management of PHEV is just attract the extensive concern of industry and academia.
Currently, when the scheduling strategy and pricing mechanism of most of invention focus concern PHEV charge and discharge are to reduce charging
Between and cost depletions；There are many more the disposition optimizations that invention work is intended to probe into PHEV charging station；Only a small amount of research is concerned about
The safety problem of charge user, and existing safety approach all relies on the key authority of authority, once trusted third party
It breaks down or falls into enemy hands, the privacy of PHEV user will be by grave danger, this serious blow PHEV participates in balancing energy management
Enthusiasm, invent one kind go center, distributed trust, it is traceable can not distort, privacy of user shielded PHEV energy safely
Amount trading scheme is of great significance.
In conclusion the prior art has the following problems:
(1) prior art is easy to happen Single Point of Faliure, once centralization mechanism breaks down or suffers a calamity, transaction authentication
It will be interfered or control with payment activity, to threaten the availability and reliability of system；
(2) prior art lacks privacy and anonymity, and centralization mechanism has the hidden danger compromised, and there are prestige for privacy of user
The side of body, the vehicle of power surplus lack the enthusiasm that power exchange is participated in as supplier；
(3) low efficiency, for substantial amounts, geographically distributed PHEV, the distal end Grid Central of the prior art regulates and controls effect
Rate is low, and especially in the social hotspots region far from power grid, retractility is poor, and many stagnation vehicles are had more than needed big energy, while again
There are many vehicles to be badly in need of charging to complete plan of travel, and far charging of detouring will cause additional time cost and energy consumption；
(4) in the prior art, when carrying out PHEV user's checking, delay is big, with duration and low efficiency, increases the energy
Consumption.
Summary of the invention
For above-mentioned deficiency in the prior art, high system safety provided by the invention, user privacy are high, energy is handed over
Easy low efficiency and retractility is good and the user's checking used time short and high-efficient PHEV power exchange system based on alliance's block chain
System and its method of commerce, ensure that the availability and reliability of system, avoid additional time cost and energy consumption, solve
Security of system of the existing technology is low, user privacy is low, power exchange low efficiency and retractility is poor and user tests
