Description
Technical field
The present invention is more particularly to a kind of based on secondary valency sealed auction for active power of wind power field control and distribution mechanism
Active power of wind power field distribution method.
Background technology
With the continuous ripe and Wind Power Generation Industry competition constantly aggravation of China's wind power technology, wind-powered electricity generation is progressively to the hair that becomes more meticulous
Exhibition, this also constantly expedites the emergence of new technology.There was only that a kind of or a few model unit is different from one wind power plant of past, it is more next
More wind power plants is according to the wind regime difference of units' installation position, personalized customization unit, makes power generation performance, the mechanicalness of unit
The wind regime of energy, security performance etc. and installation site is adapted, and more effectively lifts the earning rate of wind power plant investment, optimizes wind power plant
Reliability.Each wind power equipment producer puts into substantial amounts of resource, the unique technology lifting market competitiveness of research and development, and traditional
Homogeneous competitive environment is compared, and under the new situation, wind power equipment producer is to more paying attention to the protection to technology privacy.
As installed capacity of wind-driven power is constantly lifted, to ensure the safety and economic operation of power network, active power of wind power field control
More and more important, " wind power plant must have power adjusting ability to China's wind-electricity integration standard clear stipulaties, and can be adjusted according to power network
Degree departmental instruction controls its active power to export.In order to realize the control to active power of wind power field, wind power plant need to configure active
Power control system, receive and perform the active power controller signal that a traffic department distant place is sent automatically." traditional wind power plant has
Work(power controller, mainly includes：Start and stop method and proportionate allocation.The working method of start and stop method is：When wind power plant is active
When output is higher than setting value, Wind turbines are carried out with orderly closedown until Power Output for Wind Power Field is below setting value；Work as power
During less than given threshold, sequence starting Wind turbines simultaneously allow unit completely to send to make Power Output for Wind Power Field close to setting value.Ratio
The working method of distribution method is：In unit available horsepower ratio, wind power plant active power output task is assigned to each unit.These sides
Method is generally established in the basically identical hypothesis of each unit mechanical performance of wind power plant, security performance, and emphasis ensures that wind power plant is active
Power tracking traffic department requires that the wind power plant that these methods are used for unit customization of individual character has some shortcomings, mainly includes：
（1）Necessary consideration is lacked to the characteristic of unit, it is difficult to play the advantage of unit personalized customization, in some instances it may even be possible to offset machine
The advantage of group personalized customization；
（2）Traditional active power of wind power field controller needs to grasp each unit information comprehensively, to ensure to distribute to the active of unit
The reasonability of power, the comprehensive reliability for ensureing active power of wind power field, unit are customized under environment, and wind power equipment producer is by ten
Divide and pay attention to the information that protection is related to technology privacy, active power of wind power field controller is difficult to the Complete Information for grasping each unit, made
Traditional active power of wind power field control model faces feasibility challenge；
（3）The generated energy of each unit of wind power plant, the technical advantage of unit, it is difficult to embodied on gene-ration revenue, be objectively difficult to accumulate
Pole promotes wind power equipment manufacturer to greatly develop new technology.
The content of the invention
In order to solve above mentioned problem existing for prior art, the present invention proposes a kind of wind power plant based on secondary valency sealed auction
Active power distribution method, active power of wind power field controller is according to time valency sealed auction principle to wind power plant active power output task
Distribution is optimized, this method advantageously ensures that the reliability of active power of wind power field, may advantageously facilitate skill between each unit
Art competes, and advantageously reduces the complexity of active power of wind power field control system.
The technical scheme that the present invention solves above-mentioned technical problem comprises the following steps：
1）Active power of wind power field controller announces new one after the active power reference value of wind power plant next cycle is connected to
The active power controller cycle starts, the auction of new active power controller cycle first time Generation Right starts, and valency seals in due order
Mode auctions active power Generation Right；
2）Each Wind turbines controller can send out wattful power after receiving the auction of wind power plant Generation Right and starting message according to the unit
Rate, the unit have been got the bid Generation Right, the unit residue generating capacity, calculate the unit bid price and competitive bidding Generation Right；
3）Active power of wind power field controller, when time bidding price, is selected when time bidding price highest machine according to administrative unit
Group determines that acceptance of the bid unit obtains as acceptance of the bid unit, and according to the second price in time submitting a tender, wind power plant is unallocated active power
Generation Right size, and when secondary competitive bidding result notifies administrative each unit；
4）After each generator set controller receives competitive bidding results messages, judge whether that the machine is got the bid, if the machine is got the bid, then update this
The accumulative acceptance of the bid Generation Right of machine, residue can generating capacities；
5）Whether active power of wind power field controller is whether 0 decision auction continues according to wind power plant active power to be allocated, such as
Active power that fruit wind power plant is unallocated is not 0, and auction continues, and wind power plant has power controller to announce that new Generation Right auction is opened
Begin, if the unallocated active power of wind power plant is 0, auction stops, and active power for wind power controller is announced to auction to administrative unit
Terminate；
6）Each Wind turbines controller calculates next controlling cycle the unit and passes through competitive bidding after the information of End of Auction is received
The accumulative Generation Right obtained, unit are run accordingly in next controlling cycle, and active power is delivered by the Generation Right of acquisition.
The technical effects of the invention are that：Active power of wind power field controller of the present invention is according to time valency sealed auction principle pair
Wind power plant active power output task optimizes distribution, and each Wind turbines can send out power, power of having got the bid, remaining hair according to the unit
Electric energy power determines the bid price of the unit, and active power of wind power field controller selects bid most according to time valency sealed auction principle
For high unit as acceptance of the bid unit, the Generation Right size that acceptance of the bid unit obtains is the bid price of the second high unit of bid, the mistake
Journey is repeated, until wind power plant active power output task is assigned.This method advantageously ensures that active power of wind power field
Reliability, technology competition between each unit is may advantageously facilitate, advantageously reduce the complexity of active power of wind power field control system.
