It is further preferred that the price P2 step-length is set as 0.001 yuan.
It should be noted that the effect for calculating and obtaining the relationship inspection table of P2 and Load is to lead in subsequent step Load value is crossed to find corresponding P2 value as Spot Price and exported.
It should be noted that current time price P1 refers to the power supply price at current time.When initial, currently Moment price refers to the price that power supply bureau initially provides;And after first time operation, present price refers to previous moment Present price of the price exported after calculating as second of operation.
It should be noted that the present invention considers the discontinuous variation of price, therefore minimum unit step-length is set as 0.001 Member so needs to calculate number no more than 1000 in total, so that method is actually more quickly accurate.
Preferably, the S5 the following steps are included:
S51: it is acquired when reaching T2 and determines currently practical generated output P;
S52: it is poor that Load all in inspection table are made with currently practical generated output P respectively, and it is the smallest to select absolute value Load value, and corresponding P2 is found by inspection table.
Preferably, the T2=T1+5min.
Preferably, the initial value of T1 is=Ta-5min.
It should be noted that being spaced five minutes time to being checked from calculating inspection table, advantageously ensure that Operational capability.
Ta-5min, i.e. first five minute at sunrise moment are set by T1, it is ensured that the sunrise moment can calculate input electricity price P2。
