4) judge whether next month each day has repair schedule successively, skipped if not, otherwise to there is the next of repair schedule task
Each day of the moon, two kinds of methods of operation under each day peak load and low ebb load are generated respectively；
Described the step of generating two kinds of methods of operation under each day peak load and low ebb load, is as follows：
4-1) the power transmission and transforming equipment repair schedule arranged according to this day, deletes each scheduled overhaul one by one in basal profile data
Power transmission and transforming equipment obtains intermediate data；
Intermediate data, the peak load of this day that this day unit outage plan, step 3) obtain and low ebb load 4-2) are based on, is examined
Worry system spinning reserve and network loss adjust unit output and load, make system power in a basic balance, generating run mode slightly counts
According to comprising the following steps：
4-2-1) generator gross capability and load total amount in statistical basis mode data, if generator gross capability is Pgorg, load is total
It measures as Plorg；
The unit of the daily planning stoppage in transit 4-2-2) is searched in intermediate data, and the gross capability for counting these units is Pgstop, so
These units are deleted in intermediate data afterwards；
4-2-3) peak load of this day or low ebb load and P are calculated by formula (6)lorgDifference DELTA Pl, and adjust each node of the whole network
Load makes the whole network load total amount be Pllim：
ΔPl=Pllim-Plorg (6)
Wherein, the P when calculating peak load modellimFor the peak load of this day；The P when calculating low ebb load methodllimFor this
The low ebb load of day；
If Δ Pl＞ 0 then increases load at equal pace in each load bus of the whole network, if Δ Pl＜ 0, then in each load bus of the whole network
Load shedding at equal pace so that the whole network total load is Pllim；
4-2-4) the unit of meter and planned outage, and consider network loss size in the ratio of generation load in initial data, calculate system
System generator need to increase output or subtract output total value Δ Pg, as shown in formula (7)：
