Pmax n, each active lower limit of a group of planes is respectively Pmin 1、Pmin 2、Pmin 3、…、Pmin n, the real-time active respectively P of each group of planes1、P2、
P3、…、Pn, each group of planes increases active PDifference can be increasedFor：Pmax 1-P1、Pmax 2-P2、Pmax 3-P3、…、Pmax n-Pn, each group of planes drops
Active PIt can dropRespectively：P1- Pmin 1、P2- Pmin 2、P3- Pmin 3、…、Pn- Pmin n, the rate for incorporation into the power network of each group of planes is respectively Pri1、
Pri2、Pri3、…、Prin；
According to collected wind turbine group of planes service data, scene judgement is carried out first before each power distribution：
If 1. PAlways>P1+ P2+ P3+…+Pn, then perform the following active strategy of increasing：
When increasing active tactful, each group of planes rate for incorporation into the power network is ranked up, and presses the descending order of group of planes rate for incorporation into the power network, according to
The active power of secondary each group of planes of increase, is specifically expressed as follows：
If electricity price is ordered as：Pri1>Pri2> Pri3>…>Prin, then increase it is active be ordered as a group of planes 1,2,3 ..., n, if two machines
Group's electricity price is identical, i.e. Prii=Prij(i, j≤n), then contrasting increasing for two group of planes when sorting has work value PIt can increaseIf, PIt can increase i>PIt can increase j,
Then by group of planes i increasing is active come group of planes j before；
After sequence, P is increased successively according to clooating sequence1、P2、P3、…、Pn,
When an i group of planes is when having work value to reach the active upper limit, i.e. Pi= Pmax iWhen (i≤n), then continue to increase Pi+1, until PAlways=P1+
P2+ P3+…+Pn；
If 2. PAlways<P1+ P2+ P3+…+Pn, then perform the following active strategy of drop：
When dropping active tactful, equally each group of planes rate for incorporation into the power network is ranked up, and by ascending suitable of group of planes rate for incorporation into the power network
Sequence, reduces the active power of each group of planes, is specifically expressed as follows successively：
If electricity price is ordered as：Pri1<Pri2< Pri3<…<Prin, then drop it is active be ordered as a group of planes 1,2,3 ..., n, if two machines
Group's electricity price is identical, i.e. Prii=Prij(i, j≤n), then contrasting dropping for two group of planes when sorting has work value PIt can dropIf, PIt can drop i<PIt can drop j,
Then by group of planes i drop is active come group of planes j before；
After sequence, P is reduced successively according to clooating sequence1、P2、P3、…、Pn,
When an i group of planes is when having work value to reach active lower limit, i.e. Pi= Pmin iWhen (i≤n), then continue to reduce Pi+1, until PAlways=P1+
P2+ P3+…+Pn；
3. special scene is divided into two classes：
One is that active desired value is higher than the active upper limit sum of all group of planes, i.e.,：PAlways>Pmax 1+Pmax 2+Pmax 3+…+Pmax n, then this
Shi Zhihang increases active strategy, until all group of planes are exerted oneself with active higher limit, i.e.,：P1= Pmax 1, P2= Pmax 2, P3=
Pmax 3..., Pn= Pmax n；
4. two be that active desired value is less than the active lower limit sum of all group of planes, i.e.,：PAlways<Pmin 1+Pmin 2+Pmin 3+…+Pmin n, then
The active strategy of drop is now performed, a group of planes is shut down by active clooating sequence is dropped, until always active reach active desired value, i.e.,：P1=
Pmin 1, P2=Pmin 2, P3=Pmin 3..., Pn=Pmin n, and PAlways=Pmin 1+Pmin 2+Pmin 3+…+Pmin n (i<n)。
6. a kind of novel air motor group of planes active power according to claim 4 optimizes the optimization distribution side of distributor
Method, it is characterised in that：The blower fan group of planes operational factor includes electricity price, generating capacity, put into operation the time.
7. a kind of novel air motor group of planes active power according to claim 4 optimizes the optimization distribution side of distributor
Method, it is characterised in that：Wind turbine group of planes active power optimization distributor substitutes control function of the AGC system to a blower fan group of planes,
The real-time fan operation information that EMS system is uploaded is received, while not changing between AGC system and wind turbine group of planes EMS system
Communication function, the communication of AGC system and power network is not influenceed.
