When battery pack SOC calculate battery pack discharge capacity, so that putting for battery pack can be calculated according to the discharge capacity of battery pack
Electric rate.In the charging time section in each period, solar panel uses MPPT (Maximum Power Point
Tracking, MPPT maximum power point tracking) algorithm, it realizes and is charged with highest efficiency to battery pack, and terminate in charging time section
When calculate battery pack charge volume, thus according to the charge volume of battery pack calculate battery pack charge efficiency.
Therefore, the status information of battery pack can be judged according to the discharge capacity and charge volume of battery pack in current period, such as
Charging and discharging capabilities, activity of battery pack of battery pack etc..
S3 obtains environmental parameter locating for solar street light in the charging time section in next period, and environmental parameter is made
Charge power pattern function is established for the first input variable, to estimate charging of the battery pack in the charging time section in next period
Power.
According to one embodiment of present invention, environmental parameter may include outdoor environment temperature, Intensity of the sunlight and longitude and latitude
Degree, wherein charge power of the battery pack in the charging time section in next period is estimated according to following charge power pattern function:
Wherein, PIt fillsFor charge power of the battery pack in the charging time section in next period, α1、α2、β1、β2、γ1、γ2WithFor charge power model parameter, can be configured according to concrete model, T1、LxIt is and outdoor environment temperature, sunlight with NE
According to corresponding first input variable of intensity and longitude and latitude.
Specifically, the principal element for influencing charge power of the battery pack in charging time section includes current outdoor environment temperature
Degree, Intensity of the sunlight and longitude and latitude etc..Wherein, outdoor environment temperature will have a direct impact on the charging performance of battery pack, thus
The charge power for influencing battery pack is connect, outdoor environment temperature is higher, and the charging performance of battery pack is higher, but works as outdoor environment temperature
When degree is more than given threshold, outdoor environment temperature is higher again, and the charging performance of battery pack is lower, therefore, the charging function of battery pack
Rate is closely related with outdoor environment temperature；Intensity of the sunlight is related to the output charge power of solar panel, sunlight
Stronger according to intensity, output charge power is higher, conversely, Intensity of the sunlight is weaker, output charge power is lower；Longitude and latitude with too
Solar angle is related, thus also with the output charge power indirect correlation of solar panel.To pass through charge power mould
Type function PIt fills=ξ (u1, u2..., un), wherein u1、...、unThe as input sample value (i.e. the first input variable) of model, ξ
() is pattern function.
S4, by the remaining capacity of battery pack, the status information of battery pack and battery pack in current period in next period
Charge power in charging time section is as the second input variable, and according to the second input variable to the discharge time in next period
The permitted discharge capacity of battery pack is modeled to estimate the permitted discharge capacity of battery pack in section.
According to one embodiment of present invention, the permitted discharge capacity of battery pack is estimated to obtain according to drag:
Y=f2(∫Φ*f1(∫E*u+θ1)+θ2)
Wherein, u is the input vector after the second input variable normalized, and E and Φ are the second input variable in model
Weight parameter vector matrix, θ1And θ2For the amount of bias of model, f1() and f2() is S type function, and y is model output value.
Specifically, battery pack current residual electricity of permitted discharge capacity and battery pack, battery in discharge time section
Charge power of the status information and battery pack of group in the charging time section in next period is closely related, therefore, can be according to working as
The remaining capacity of battery pack, the status information of battery pack and battery pack filling in the charging time section in next period in the preceding period
Electrical power is modeled come the permitted discharge capacity of battery pack in the discharge time section to next period to estimate battery pack institute
The discharge capacity of permission.
Wherein, the remaining capacity of battery pack is bigger in current period, and battery pack permits in the discharge time section in next period
Perhaps discharge capacity is bigger, conversely, the remaining capacity of battery pack is smaller in current period, battery in the discharge time section in next period
The permitted discharge capacity of group is smaller；When the charge-discharge performance of the status information of battery pack such as battery pack and the electric discharge in next period
Between the permitted discharge capacity of battery pack is related in section, the charge-discharge performance of battery pack is higher, and efficiency for charge-discharge is higher, next period
Discharge time section in the permitted discharge capacity of battery pack it is bigger, conversely, the charge-discharge performance of battery pack is lower, efficiency for charge-discharge
Lower, the permitted discharge capacity of battery pack is smaller in the discharge time section in next period；Battery pack is in the charging in next period
Between charge power in section directly affect the permitted discharge capacity of battery pack in the discharge time section in next period, charge power is got over
Greatly, the permitted discharge capacity of battery pack is bigger in the discharge time section in next period, conversely, in the discharge time section in next period
The permitted discharge capacity of battery pack is smaller.
Therefore, by the remaining capacity of battery pack, the status information of battery pack and battery pack in current period in next period
Charging time section in the main affecting factors such as charge power as the second input variable, establish and battery pack is permitted puts
Mathematical model between electricity, the mathematical model can indicate are as follows: y=f (u), wherein y representative model output valve, u are each
Input vector u=(u1, u2..., um), be the input of a various dimensions, these input variables be it is above-mentioned it is main under the influence of
The variable of the permitted discharge capacity of battery pack, is input to these variables mathematical modulo of the invention in the discharge time section in one period
In type, so that it may the permitted discharge capacity of battery pack in the discharge time section in next period be calculated.
Wherein, f1() is the processing function of input vector,σ, β in formula,It is given
Parameter, f2()=f1() is the processing function of intermediate vector.
S5, according to the permitted discharge capacity of battery pack to the lighting power of LED light in discharge time in next period section into
Row control.
According to one embodiment of present invention, according to the permitted discharge capacity of battery pack to the discharge time section in next period
The lighting power of interior LED light is controlled, comprising: the discharge time section in next period is divided into multiple periods；According to battery
The lighting power of the permitted discharge capacity control LED light of group first rises within multiple periods in staged, again under staged
Drop, wherein the lighting power of LED light remains unchanged within each period.
That is, can be needed the period of street lighting be divided into multiple sections at night, as darkness deepens for the colour of sky,
The lighting power of control LED light gradually rises, and improves the brightness of illumination of LED light, as the colour of sky is more and more brighter, then controls LED light
Lighting power gradually decrease, reduce the brightness of illumination of LED light, realize that the brightness of illumination of LED light and actual illumination demand are adaptive
It answers, avoids energy waste, effectively realize energy conservation.
