Postpone the minimum value of the maximum actual load of any metering period;This is carried out according to the result of the last iteration after optimization to change
Generation.
Particle swarm algorithm includes successive ignition process, and the number of iteration is preset the number of iterations, is generally chosen as 20 times.
Specifically, due to being the optimization for carrying out all the period of time, the variable for carrying out optimization is more (such as when m=2880
Have 2880), the result of certain an iteration is likely to be at local convergence, can not continue iteration, but the result of local convergence for
It is not necessarily optimal for the overall situation.
Last iteration is carried out according to particle swarm algorithm, after the result for obtaining last iteration, judges that the last time changes
Whether the result in generation is in local convergence, if the total revenue difference of upper 2 iteration is less than preset value ε and can determine whether as local convergence;
If being not at, directly according to the result of last iteration by the P after iterationi bIt re-enters, carries out current iteration;
If being in, the result of last iteration is optimized using unit time optimisation strategy, specifically to unit
Income in time optimizes, and completes current iteration according to optimum results.
It should be noted that metering period includes multiple unit time, each unit time includes multiple moment.For example,
Metering period is the moon, and the time interval between the two neighboring moment is for hour, the unit time can be day.
For there are the P that local convergence result generates last iterationi bSequence is segment according to unit time cutting, for
Any one unit time segment, the basic principle of unit time optimisation strategy are to keep the unit time maximum actual load not
Minimum value more than the DCT that the step of before obtains, and keep in the result (charge-discharge electric power curve) of last iteration
SOC, the SOC of end time point energy storage device of the start time point energy storage device of the unit time are constant, to the unit time
The charge-discharge electric power at each moment optimizes.
Unit time optimization front and back, the integral of the unit time charge-discharge electric power curve is identical, illustrates any fractional unit
The SOC of time-optimized front and back, the end time point energy storage device of the segment is constant.
It is to guarantee that the optimum results of some any unit time do not influence other using the advantages of unit time optimisation strategy
Do not carry out that the step optimizes as a result, the local optimum of i.e. single unit time will not produce the constraint condition of earnings pattern
Raw conflict, thus before influencing iteration result validity.This strategy when multivariable (m=2880) optimizes it is possible to prevente effectively from fall into
Enter the defect of local optimum, while can significantly promote calculating speed.
The embodiment of the present invention can be obtained by optimize the iteration result when iteration result is local convergence
Globally optimal solution can obtain the time series of the charge-discharge electric power of all the period of time, so as to obtain more accurate each metering period
