Description
Technical field
The invention belongs to system for distribution network of power technical fields, and in particular to a kind of towards electric vehicle and wind light generation
Power distribution network regulation device and method.
Background technology
Constantly increase in global power demand, the fossil energies such as coal it is increasingly in short supply, can under the background that environment constantly deteriorates
Duration becomes the keyword of the following power network development, is embodied in a large amount of regenerative resources and distributed energy in power distribution network
The access and application of side.It is increasingly subject to global concern as the clean energy resource of representative using wind power generation module, photovoltaic generating module, and
The form of power generation (distribution generation, DG) accesses power distribution network in a distributed manner so that power distribution network is gradually to active
Power distribution network changes.
Distributed energy refers to providing the novel of energy supply nearby to user using the mini-plant for being distributed in user side
Energy utilization patterns.Renewable distributed power generation can effectively reduce transmission losses close to load end, have small and flexible, effect
The advantages such as rate is high, cost of investment is low, are one of important development directions of intelligent grid.But there is also one for distributed energy
A little problems, distributed power generation are influenced by factors such as geographical location and weather conditions, intermittent stronger, output power less stable
And the time is upper also inconsistent with load fluctuation, causes peak-valley difference big, it is higher to the capacity transfer of power grid, pressure regulation Capability Requirement.And mesh
The capacity of preceding energy-storage system is also limited, cannot provide power for a long time to cope with deficiency (the distribution hair of distributed power generation capacity
Electricity needs 10%~20% spare capacity).
Renewable energy power generation unit (such as photovoltaic generating module and wind power generation module), renewable etc. pollution-free with its
Advantage, by very high attention.However, this kind of generator unit is while making full use of renewable and clean energy resource, and between having
The distinguishing feature of having a rest property and randomness.On the one hand the fluctuation of its output power causes the decline of power quality；On the one hand it increases
Difficulty electric energy allotment to output and utilized.The energy-storage system that certain capacity is configured for regenerative resource, can effectively press down
The fluctuation of renewable energy power generation output power processed improves the safety and stability of operation of power networks, increases power grid to renewable
The utilization rate of energy power generation.
Meanwhile in real life, with automobile popularizing in people's daily life, administers automobile exhaust pollution and have become
The livelihood issues paid close attention to jointly for the common people and government.Nowadays Development of EV is energy conservation and environmental protection and the demand of low-carbon economy, by
In its special driven by energy mode, efficiency of energy utilization can be improved and reduce the pollution to environment, be just increasingly subject to people
Concern.
Electric vehicle (electric vehicle, EV) technology it is ripe day by day, country also put into effect policy encourage and energetically
Promote the use of electric vehicle so that the ownership for having energy saving and environment-friendly advantage electric vehicle increases substantially.Meanwhile with
It increasing for grid-connected wind-light storage power generation and electric vehicle number, their input and exits the injection work(for influencing load bus
Rate, and the random changing factor of wind-light storage generator operation, such as solar energy and wind power generation amount be by weather effect of natural conditions, from
And influence entire distribution network planning.Therefore, it is largely accessed towards electric vehicle and wind light generation so that have high efficiency intelligence
Energy power distribution network regulating strategy is highly important.
The appearance of wind power generation module, photovoltaic generating module and electric vehicle so that distribution network planning compared with the past has
The uncertainty of bigger needs to be innovated in method in prcgramming ideas, for contain wind power generation module, photovoltaic generating module and
The new distribution system planning of electric vehicle theorizes and application foundation.
If the power generation that both electric vehicle and distributed generation unit can be controlled send outside total amount stablize setting limit it
It is interior.Regenerative resource can be both made full use of in this way, makes full use of electric transmission line channel, reduce line power fluctuation, and enhance
The adjustable property of transmitted power.
