1) if plan unit i is that R (i, t) exceeds the rate of load condensate upper limit in the planned outcome of t month arrangement

Then will plan electric weight by the power generation load rate upper limit

And electric weight temp adjusted in record; Travel through other month, search the month t ' of the temp electric weight of can dissolving; But travel through from big to small residue plan unit j ∈ E according to remaining the generated energy ability t month, find the temp electric weight of can dissolving, and can cut down the plan unit j of generation schedule the t ' moon, carry out following operation:

R(i,t)＝R(i,t)-temp

R(i,t′)＝R(i,t′)+temp

R(j,t)＝R(j,t)+temp
