And reliability.
Embodiment two：
A kind of a kind of acquisition methods of the electric dispatching plan data provided for previous embodiment are be provided
Concrete application example, reference can be made to as described below：
The first step：The basic data of the power network in electric dispatching plan is obtained by power system monitoring system；The basis
The voltage magnitude of each node, voltage phase angle, active power and reactive power in topological structure of electric of the data including power network；Base
Plinth data can turn into flow data again, can be by the power equipment collecting part data on the node of each on power network, and by tide
Stream calculation obtains whole related datas.
Second step：Type according to power network in electric dispatching plan, it is determined that relation factor corresponding with the power network type,
And additional data is determined according to relation factor.Can specifically determine according in relation factor table set in advance.Hereinafter carry out one
Plant the labor during practical operation：
(1) when power network is sending end power network, it is considered to which the clean energy resource such as wind energy of sending end power network is sent outside.Transregional direct current
An important function in electric dispatching plan is that the clean energy resource such as wind energy for realizing sending end power network is sent outside.Presently mainly lead to
Cross the mode of raising low ebb electricity sent outside as far as possible ensures wind electricity digestion come the mode to sending end power network offer wind electricity digestion space.
But which will cannot need to carry out the actual conditions of the clean energy resourcies such as direct current plan and wind-powered electricity generation in electric dispatching plan
It is unified to consider, cannot also give full play to the regulation performance of normal power supplies, it is therefore necessary to using conventional energy resource and clean energy resource as
The relation factor of sending end power network is accounted for, and in abundant external data, preferably increases data below newly as additional data：
1.1) the default side of scene sent outside the need for being given according to 96 periods；
1.2) electricity transaction be given according to 96 periods advises that power value, the bound of 96 forms adjust interval, suggestion
Electricity etc.；
1.3) information such as the start-stop plan of supporting normal power supplies, regulation performance and suggestion electricity；
1.4) direct current is sent outside adjustment is interval and the information such as peak-trough electricity force constraint.
Wherein, the 96 above-mentioned periods by 24 hours one day it is to be understood that be divided into 96 periods, each period is 15 points
Clock, above-mentioned data value can correspond respectively to each period, and the additional data of a day is 96 values so that the data of acquisition have
Representativeness, can accurately reflect system situation.
Consider sending end power network merely sends the security constraint that demand is difficult to meet receiving end power network sometimes outside, it is therefore necessary to examine
Consider the accompanying information of receiving end power network, it is the active balance and emphasis section of receiving end power network to influence larger.
(2) when power network is receiving end power network, it is considered to the active balance constraint of the receiving end power network, active balance is constrained and is made
It is the relation factor of receiving end power network.In abundant external data, data below is preferably increased newly as additional data：
2.1) the active bound for providing such as water power, thermoelectricity, clean energy resource and other power supply types according to 96 periods can
Adjust interval；If cannot adjust, the upper limit is made to be equal to lower limit；
2.2) the receiving end network load predicted value be given according to 96 periods；
2.3) the receiving end dispatching of power netwoks plan be given according to 96 periods (also known as total openning plan)
2.4) interconnection cross-section limitation and original plan value between all interconnection provinces for being given according to 96 periods.
It should be noted that when the direct current conveying power in electric dispatching plan is dissolved in drop point province Dan Sheng completely,
Interconnection cross-section limitation between all interconnection provinces be given according to 96 periods and just can not be included in above-mentioned additional data
Direct current in beginning planned value, only electric dispatching plan conveys power and also has other interconnection provinces to be total in addition in drop point identity
With dissolving, then the interconnection cross-section limitation and original plan value between all interconnection provinces that will be given according to 96 periods are needed
As additional data.
(3) when power network is receiving end power network, it is considered to the emphasis section tidal current constraint of the receiving end power network, by emphasis section tide
Stream is constrained as the relation factor of receiving end power network.In abundant external data, data below is preferably increased newly as additional data：
3.1) the initial power flow solutions of emphasis section；
3.2) active po wer sensitivity of the direct current drop point to concern section.Wherein it is possible to the adjustment of direct current is multiplied by into sensitivity recognize
To be the change of power flow (have ignored influence of other power supplys to the section) of the section.
3rd step：Because above-mentioned data are all from different scheduling institution or system monitorings, therefore also need to above-mentioned base
Plinth data and additional data are matched and spliced.Matching ensures to splice successful committed step.This gives following
Several specific matching ways：
Matching way one：Constant mark is relied on to be matched.Logic matching can be carried out by constant mark.For example,
Each province is considered as being the regional for dividing power network that there is respective identity in each province.Each direct current
Mark is needed to send receiving end province (i.e. identity), the contact section between each province is also required for mark to send receiving end province (i.e. body
Part mark).At this point it is possible to the interconnection that the graphics logic of the Points And lines in electric power topological structure is obtained between all provinces is closed
System, the data in each province area can then be corresponded.Additionally, the supporting power supply of direct current is also required for the mark of fixation
Know, can be matched with direct current.
Matching way two：Logical expression is relied on to be matched.Under normal circumstances, relying on the matching of constant mark has a spy
There is one-to-one relationship in the thing of point, i.e. splicing, but one-to-many relation is there is likely to be between data, therefore can be with head
