After order, according to full factory load instruction and the last grid side received of the grid side received
Full factory load instruction calculated load changing value, and when load variations value >=(operating unit number of units
× 10), during MW, total rate of change of the most all units is that (operating unit number of units × unit holds
Amount × 1%) MW/min, single unit speed >=(single-machine capacity × 1.5%) need to be met during distribution
MW/min；
When full factory Automatic Generation Control optimizes the load variations value ＜ (operation that device (1) receives
Unit number of units × 10) MW time, then total rate of change is (operating unit number of units × single-machine capacity
× 1.5% (MW/min need to meet single unit speed >=(single-machine capacity × 1.5%) during distribution
MW/min。

In summary, pondage allocation strategy, normalization index allocation strategy and fixed point power distribution strategies
Any one strategy；
Described unit generation efficiency allocation strategy is particularly as follows: by the generating efficiency of each unit in institute
There is ratio in unit generation aggregate efficiency always to instruct with full factory load to be multiplied, obtain each unit
Load value；
Described regulations speed allocation strategy particularly as follows: by the regulations speed of each unit institute organic
The ratio regulated in total speed of group always instructs with full factory load and is multiplied, and obtains bearing of each unit
Charge values；
Described pondage allocation strategy particularly as follows: by the pondage of each unit institute organic
Ratio in the regulation total capacity of group always instructs with full factory load and is multiplied, and obtains bearing of each unit
Charge values；
Described normalization index allocation strategy is particularly as follows: by the weights of each unit set in advance
Coefficient always instructs with full factory load and is multiplied, and obtains the load value of each unit；
Described fixed point power distribution strategies is particularly as follows: by the fixed point power difference of each unit in institute
There is the accounting in the fixed point power difference of unit always to instruct with full factory load to be multiplied, obtain each machine
The load value of group；Described fixed point power difference is unit load value set in advance and actually measured
The difference of unit load value.
