By power (4) in the peak of electrical network, first by maximum generation power (5) total for regional power grid plus regional power grid peak in by merit
Rate (4), peak that is that obtain and that deduct regional power grid is sent power (2) outside, then is deducted the peak spinning reserve capacity of regional power grid
(3) peak load (1) of regional power grid, is obtained；
17th step, the difference of the peak regulation rate deducting non-thermal power plant unit by the peak load (1) of regional power grid are multiplied by non-heat supply machine
The base power (11) of group obtains the generated output lower limit (19) of non-thermal power plant unit；Subtract by the peak load (1) of regional power grid
The difference going the peak regulation rate of thermal power plant unit is multiplied by under the generated output that thermal power plant unit basis generated output (10) obtains thermal power plant unit
Limit value (20)；Pump-storage generator basis generated output (9) is converted into pump-storage generator basis and draws water power (17)；
18th step, by the generated output lower limit (19) of non-thermal power plant unit plus the generated output lower limit of thermal power plant unit
(20), that obtain and deduct pump-storage generator basis and draw water power (17), obtain the generated output lower limit of regional power grid
(18)；
19th step, deduct the peak-valley ratio of the peak load of regional power grid by the peak load (1) of regional power grid, the difference obtained
Value is multiplied by the peak load (1) of regional power grid, obtains the low ebb load (12) of regional power grid；By the peak load 1 of regional power grid
The peak-valley ratio of power is sent on the peak deducting regional power grid outside, and the difference obtained is multiplied by the peak of regional power grid sends power 2 outside,
Low ebb to regional power grid sends power 13 outside；Deduct by the peak load (1) of regional power grid in the peak of regional power grid by power
Peak-valley ratio, the difference obtained is multiplied by the peak of regional power grid by power (4), obtains in the low ebb of regional power grid by power
(14)；
20th step, send the low ebb load (12) of regional power grid outside power (13) plus the low ebb of regional power grid, the sum obtained
The low ebb deducting regional power grid is interior by power (14), then the low ebb deducting regional power grid turns spare capacity (15), obtains region electricity
The low ebb workload demand (16) of net；
21st step, the low ebb workload demand (16) of regional power grid is deducted the generated output lower limit (18) of regional power grid,
Obtain the wind-powered electricity generation under regional power grid maximum start-up mode and receive power；
Finally setting up rectangular coordinate system, abscissa is the peak load of regional power grid, vertical coordinate be wind-powered electricity generation receive power, draw with
Upper three points, are connected first with second point, first line segment smooth with thirdly use respectively；I.e. draw out based on region
Under network load situation of change, wind-powered electricity generation receives power curve.
