Description
Technical field
The invention belongs to the automatic management field, particularly relate to the management method of sub-district electric automobile.
Background technology
It is power that electric automobile is meant with the vehicle power, goes with power wheel, meets the vehicle of road traffic, the requirement of safety regulations each item.In recent years; Along with the continuous growth of energy prices and the continuous maturation of electric vehicle engineering; And the intelligent grid foundation of many countries in the world that convenient charging service can be provided; Electric automobile has obtained countries in the world consumers' concern, and each big famous automobile factory commercial city is released novel electric vehicle one after another.Countries in the world government has also released support one after another, has promoted the policy of electric automobile, and wherein, China has set up " electric automobile major scientific and technological project " in Tenth Five-Year Plan Period, unites tackling key problem through organizing enterprise, institution of higher learning and scientific research institution.In addition, for satisfying the charging demand of a large amount of electric automobiles, auxiliary facilities such as electric automobile charging station have also begun to build pilot in each province.The China national electrical network also proposes in working conference in 2010, as a part of building intelligent grid, closely follows up with the electric automobile development trend, the Large scale construction electric automobile charging station.Therefore can predict, in very long one period in future, the electric automobile market in the China and even the world will be increased fast.
When charging, electric automobile can bring certain pressure to mains supply as a high power load.Especially after considering that electric automobile is popularized on a large scale; In sub-districts such as office building parking lot, shopping centre or residential area; The electric automobile user is numerous, the charging interval concentrated, and part sub-district grid equipment is outmoded, does not support high power to supply power for a long time; Therefore the caused long-time centrality high power power supply meeting of the intensive charging behavior of sub-district electric automobile influences the fail safe and the stability of electrical network to the impact that sub-district grid equipment and even urban distribution network cause.Therefore, effectively sub-district charging management system for electric automobile and method are extremely important.
Because accept the electric automobile of service and the randomness that is the charging interval, queuing phenomena is inevitable service time.Increase the grid power resource and can improve service ability and reduce queuing phenomena, but certainly will increase huge electric grid investment like this, in addition, electrical network also can supply exceed demand and cause serious waste because of the grid power resource at charging low-valley intervals such as morning, commuter times.Because the electric automobile user alters a great deal to the requirement of charging service quality; Even if need accepting the charging of electrical network immediately, the fraction emergency user needs cost great number charging expense; Some priority user hope can higher price-performance ratio charging, and numerous economic users can be under the prerequisite of giving with minimum charge the tolerance long period etc. to be charged.Therefore; The client's number of wait service and the Changing Pattern of indexs such as regularity, the wait service time span of tolerating and power network resources utilance need be studied by electric automobile service organization; Under the prerequisite that satisfies the customer service quality requirement; Adopt the operating cost that reduces queuing system, the utilance that improves power network resources, improve service system and method for servicing.
Chinese invention patent 201010223662.7 has been announced a kind of centralized intelligence scheduling charging method of plug-in hybrid car, comprises real time information extraction, PHEV dynamic cataloging, the change of load mark, boundary condition detection etc.Chinese invention patent 201110148661.5 has been announced a kind of electric automobile intelligent interaction charging network group system, comprises a plurality of electric automobile charging pile nodes, many electric automobiles, electric automobile charging pile cluster central control node, power grid control management system, subscriber information service system.But above invention and similar invention can not be distinguished the service quality of different user, in use the sub-district, lack flexibility.Chinese invention patent 200710037521.4 discloses a kind of self-adaptation control method that is used for electric vehicle charging device.Comprise a process of utilizing the charging circuit work of charge control module control ground charging station, this invention is merely able to can not solve Organization And Management's problem of many intensive charging behaviors of electric automobile in the sub-district to the control of charging of separate unit electric automobile.China's invention 201010508215.6 discloses a kind of distributed charging pile supervisory control system and method for supervising, adopts the monitoring management system of hierarchical multi-layer, realizes the data acquisition and the charge information management of distributed charging pile.But this invention can not be carried out real-time response with electric network data, can not control the break-make of charging pile according to the peak valley fluctuation of grid power resource flexibly.Chinese invention patent 201010617141.X discloses a kind of trough charging pile of electric automobile; Charging pile adopts time relay control on/off; Charge when being implemented in the electrical network trough, but this invention can only regularly charge, can not realize real-time response with the electrical network peak valley; And can't Long-distance Control, do not possess the practicality of in the sub-district, using.
