Description
Technical field
The invention belongs to electric power system control running technology fields, are constrained more particularly to a kind of meter and transmission of electricity network operation
The orderly charge/discharge control method of electric vehicle.
Background technology
In recent years, swift and violent using electric vehicle as China's new-energy automobile industry development of representative.Country《Energy saving and new energy
Development of automobile industry plans (2012-2020)》Set up the year two thousand twenty whole nation pure electric automobile and plug-in hybrid vapour
Vehicle adds up the target that volume of production and marketing is more than 5,000,000, and national requirements city increases or update the new energy vapour in Public Service Field newly
Vehicle ratio is not less than 30%.Meanwhile charge-discharge facility scale also rapid growth, it is contemplated that the whole nation will build up charge and discharge power station to 2020
20000, charge and discharge stake 5,070,000, public charging network realize comprehensive covering of key cities and highway.
As extensive electric vehicle accesses power grid, the charging behavior of electric vehicle can generate many influences to power grid.Electricity
Electrical automobile access will change the part throttle characteristics of power grid, influences running optimizatin control and the electric network reliability of power grid, brings under voltage
The power quality problems such as drop, harmonic pollution and three-phase imbalance, can increase via net loss and influence the service life of distribution transformer,
Also need to additionally consider the charge power demand of electric vehicle and the investment of layouting of electrically-charging equipment when Electric Power Network Planning.From transmission and distribution network
Level analysis, electric vehicle directly by power distribution network access network system, charging load compare conventional load have it is stronger
Space-time randomness, more uncertainties can be brought to the operation of power distribution network.Influence of the electric vehicle access to power transmission network be
Indirectly, but as electric vehicle accesses the increase of scale, the space-time uncertainty of charging load will also influence power transmission network
Operational safety.The unordered charging of scale electric vehicle may be further exacerbated by the peak-valley difference of network load, aggravate power transmission and distribution
The operation of net is born, and the safety margin of operation of power networks is reduced.Therefore, in order to effectively avoid scale electric vehicle it is unordered charging pair
Negative effect, needs the charging behavior to electric vehicle orderly to be controlled, makes electric vehicle with controllable burden caused by power grid
Form participate in power grid regulation.Further, since electric vehicle V2G (Vehicle to Grid) technology reaches its maturity, electric vehicle
Power battery can be used as network load, can also be used as electric network source to power grid discharge, realize electric vehicle and power grid
Between bidirectional electric energy interaction.The electric discharge behavior of scale electric vehicle is orderly controlled, can be further increased electronic
Automobile participates in the flexibility of power grid regulation, can more play the energy storage effect of electric automobile power battery comprehensively.
It is mutual that the existing orderly charge/discharge control method of electric vehicle is primarily upon the electric energy between electric vehicle and power distribution network
It is dynamic, it is generally optimal or electric vehicle charge and discharge influence minimum control targe to power distribution network with power distribution network performance driving economy, it can not
So that the charge and discharge behavior of electric vehicle is orderly responded the operating condition of power transmission network, also can not play scale electricity in power transmission network level
The energy storage of electrical automobile power battery acts on.And has method and usually only consider that the performance of electric automobile power battery is filled with user
The boundary constraints such as electric discharge demand ignore the limitations such as the scheduled wish of charge-discharge facility power constraint and automobile user
Condition is still left to be desired to considering for control method limiting factor.Therefore, in order to the interactive effect of electric vehicle and power grid is opened up
Exhibition needs to design the orderly charge and discharge control machine of electric vehicle that power transmission network, power distribution network, electric vehicle link to power transmission network level
System, falls into a trap in control process and the operation of power transmission network constrains and consider a variety of restrictive conditions, to efficiently use scale electricity
The Peak Load Adjustment of the orderly charge and discharge of electrical automobile, improves the safety in operation of power transmission network.
