It is 243 × 1440 × 100=34992000 that electricity, which requests the problem of allocation plan complexity,.In the huge situation of above-mentioned complexity
Under, it will it substantially reduces and obtains the optimal efficiency and accuracy changing electricity and request allocation plan, therefore use and open in the present embodiment
Hairdo algorithm obtains the optimal electricity that changes and requests allocation plan, specifically, can be calculated using Monte Carlo treeˉsearch method or population
Method or genetic algorithm or simulated annealing.
Below by taking the treeˉsearch method of Monte Carlo as an example, the implementation process that electric control method is orderly changed in the present embodiment is carried out
Explanation.Specifically:
Step S201: parameter initialization is carried out to Monte Carlo treeˉsearch method, is specifically included: 0 moment in special time period
Do not have electric car changes electric request, and all output powers for charging the corresponding electrically-charging equipment of station are 0 in electrical changing station.
Step S202: get first change electricity request after, start Monte Carlo treeˉsearch method.Simultaneously as this changes electricity
Request changes electric request for first, and optimal changes in electricity request allocation plan: distributed change electricity request distribution change the electric moment can
Think that this changes the acquisition moment of electricity request, i.e., battery altering is carried out to electric car at once；Distribute the battery charger for carrying energy battery
The rate of charge of position can be set according to the acceptable charge power of energy battery is carried.
Step S203: get first change electricity request after first moment, judge whether to receive and new change electricity
Request, executes Monte Carlo treeˉsearch method if receiving, and determines that the optimal electricity that changes requests allocation plan, specifically:
1, step is selected.
Since current time electrical changing station contains energy battery status, recurrence selection requests the premise whether to arrive for electricity is changed
The optimisation strategy of lower optimization aim, until reaching the last one moment of special time period.Wherein, optimal policy is to change electric request
Allocation plan.
Wherein:
The arrival that electricity request is changed in setting special time period meets particular probability distribution.One provided in this embodiment
In preferred embodiment in the case that the time span that special time period is included is less than certain value, i.e., in the special time period
It is interior at most only one change electricity request occur, assume that at this time each moment in special time period change electricity request it is general
Rate all meets (0,1) bi-distribution that probability parameter is p, that is, the probability for changing electricity request is p, does not change the general of electricity request
Rate is 1-p.
Different moments electrical changing station is contained energy battery status and can be determined using the electricity calculation method of aforementioned load energy battery.
2, spread step.
If the optimisation strategy selected in selection step, does not make the objective function of optimization aim reach global optimum, or
Person's optimisation strategy can make it is certain change electricity request when being unable to satisfy, create one or more child nodes, i.e., one or more chargings
Power regulating method, and select a child node C.
3, simulation steps.
Output that one is simulated is brought into operation as a result, if the output result meets preset constraint condition from child node C
Using the functional value of the corresponding optimization aim of output result as the evaluation of estimate of the output result, if the output result be unsatisfactory for it is pre-
If constraint condition then set 0 for the evaluation of estimate of the output result.
4, backpropagation step.
The evaluation of estimate of the output result obtained with simulation steps update Meng Tekaoluo search tree child nodes C father node and
The local optimum functional value of its all ancestor node.
Step 1-4 is repeated, obtains the final optimisation strategy of current time optimization aim, and maintain a node band
The search tree of majorized function value.
Step S204: continue to determine remaining each time optimization target in special time period using method shown in step S203
Final optimisation strategy, it can obtain the optimal electricity that changes and request allocation plan.
Although each step is described in the way of above-mentioned precedence in above-described embodiment, this field
