Standby can recycle executes the above process until the difference of total load amount and total load index is less than or equal to predetermined threshold value.The optional reality
Existing mode is referred to current total load when the corresponding total load amount of current loads allocation plan cannot match total load index
The difference adjusting and optimizing parameter of amount and total load index simultaneously updates sharing of load scheme according to the Optimal Parameters after adjustment, by not
Disconnected adjustment can make total load amount that can finally meet total load index.
In the optional realization method of in the present embodiment some, the above-mentioned difference pair according to total load amount and total load index
Optimal Parameters, which are adjusted, to be realized by following formula：
Wherein, λ ' is the Optimal Parameters after adjustment, and λ is the Optimal Parameters before adjustment, and Δ is current first optimal device group
It closes or the total load amount of the second optimal device combination subtracts the value after total load index,It is preset constant.
