Step 3: calculate the load P that in each period system, the adjustable type generating set be should bear _{l1, j}, and by P _{l1, j}be designated as the first duty value such as grade.

In the multi-energy resource combined electric generating system, generating set is divided into unadjustable generator group and adjustable type generating set usually.Exerting oneself in whole power generation process of unadjustable generator group is all that can't change stable exerted oneself.The exerting oneself of unadjustable generator group comprise without forcing of the exerting oneself of adjustment type Hydropower Unit, adjustable type Hydropower Unit exert oneself, forcing of thermoelectricity unit exert oneself and the exerting oneself of nuclear power generating sets, these are exerted oneself owing to being steadily exerting oneself of system operation, service position is at the load curve base portion, and it is exerted oneself and does not participate in the adjustment process of power-balance.Adjustable type generating set in system comprises adjustable type Hydropower Unit and adjustable type fired power generating unit.

Step 5: the state that initially puts into operation of determining the adjustable type fired power generating unit.

In hybrid power system, the adjustable type fired power generating unit generally comprises the adjustable type fired power generating unit that can not shut down, adjustable type fired power generating unit and the gas turbine unit that can shut down.The adjustable type fired power generating unit that can not shut down is not carried out start and stop peak regulation (not considering the trouble hunting special case) within dispatching cycle.The adjustable type fired power generating unit that can shut down can be subject to dispatching command to arrange start and stop.The gas turbine unit capacity is little, fast response time, does and regulates the power supply use.

Consider the small-sized thermoelectricity and the combustion gas unit that participate in the start and stop peak regulation, the restriction of minimum start-stop time is arranged, while therefore considering the Unit Combination scheme of current period, need associating prediction load condition afterwards, in order to allow unit have certain buffer time started or close down, this method is selected continuous 5 periods backward that comprise the current period.So, when determining the state that initially puts into operation of adjustable type fired power generating unit, first calculate respectively the duty value minimum value such as second of the second duty value maximums such as grade of front 5 periods of dispatching cycle and front 5 periods, then according to the first setting, sequentially drop into the adjustable type fired power generating unit.

Herein; sequentially dropping into the adjustable type fired power generating unit according to the first setting is specially; first by minimum operating ratio consumption, order from low to high drops into the adjustable type fired power generating unit that can not shut down; by minimum specific consumption, order from low to high drops into the adjustable type fired power generating unit that can shut down again, and finally by the power output regulations speed, order from high to low drops into gas turbine unit.Drop into successively the adjustable type fired power generating unit, when the total installation of generating capacity of the adjustable type fired power generating unit put into operation is greater than the second maximums such as duty value such as grade of front 5 periods of dispatching cycle, and the minimum technology of the adjustable type fired power generating unit put into operation is exerted oneself summation while being less than the duty value minimum value such as second of front 5 periods of dispatching cycle, stop dropping into the adjustable type fired power generating unit, the initially state of putting into operation of adjustable type fired power generating unit is determined complete.

Above-mentioned, the minimum technology of adjustable type fired power generating unit is exerted oneself and is referred to, guarantees that boiler maintains in the smooth combustion situation of (be unlikely to cease fire or depart from temperature and the pressure of stable state), the minimal power values that unit can send.The minimum technology of every fired power generating unit provides after exerting oneself and all having been manufactured by unit producer.

Step 6: set initial period t=5.

Step 7: calculate the load that current period t adjustable type fired power generating unit be should bear under each sampling scene

and will

be designated as the C grade duty value.The C grade duty value

computing formula be:

$P_{L3,t}^m=P_{L2,t}-P_{\mathrm{New},t}^m---\left(10\right)$

Step 8: the adjustable type fired power generating unit distribution load put into operation under each the sampling scene for current period t

Sub-step 203: make Gk=1.

Sub-step 204: utilize the micro-gaining rate f of consumption _op, upgrading adjustable type fired power generating unit value of exerting oneself that each has put into operation, its formula is:

$P_{\mathrm{Gk},t}^m=\frac{f_{\mathrm{op}}-B_{\mathrm{Gk}}}{{2A}_{\mathrm{Gk}}}---\left(14\right)$
