$n_i^{ch}=\[n_1^{ch},n_2^{ch},n_3^{ch},\mathrm{...},n_{100}^{ch}\]$

In object function is stated,AndBe abstract representations, represent a vector, each vector include 100 excellent Change variable.Whether corresponding 1st charging station is built,The charging inlet quantity that corresponding first charging station is built, class successively Push away, do not repeat at this.

Needing explanation, the span of appeal optimized variable is limited by constraints, arranges corresponding constraints. It addition, there is logical relation between some variable in optimized variable, also left unused by constraints.Such as, it is assumed that the 1st time Bit selecting is put and is not built charging station, thenCorresponding, the charging pile Quantity of first position candidate is the most necessarily 0, i.e.If first position candidate builds charging station, thenThe charging pile Quantity of first corresponding position candidate must It is not 0, i.e.

Below the constraints of above-mentioned function is illustrated:

(b). charging station number constraint.The charging station too small meeting of sum of planning makes charging station scale excessive, aobvious in city So it is difficult to the charging station that construction scale is the biggest；The charging station sum of planning too much can make charging station small scale and dense distribution, Also the total arrangement of urban construction is influenced whether, it is therefore necessary to the charging station sum of planning is retrained:

$N_{min}^s\≤\underset{i=1}{\overset{n_c}{\Σ}}{y}_i^s\≤N_{max}^s$

Wherein,Represent lower limit and the upper limit of charging station sum respectively.

(c). charging station capacity-constrained.It is limited by the factor such as power pipeline or Transmission Cost, the appearance of usual each charging station Amount also needs to use restraint, and the quantity of charging inlet in charging station is used restraint herein:

$N_{min}^{ch}\≤n_i^{ch}\≤N_{max}^{ch}$

(d). logical constraint.Obviously, charging inlet quantity in charging stationWith the binary change representing whether charging station is built AmountBetween there is constraint in logic: whenTime,Represent that i-th charging station hasIndividual charging inlet；WhenTime,Represent that i-th charging station is not built.Therefore following logical constraint can be built:

$\left\{\begin{array}{c}{n}_i^{ch}-M\·y_i^s\≤0\\ y_i^s-n_i^{ch}\≤0\end{array}\right.$

Wherein, M is a sufficiently large real number.It addition,And x_ijIt is 0-1 variable,For nonnegative integer, therefore may be used To write out:

And

Corresponding charge requirement D_jMust be met in a certain charging station, therefore be had:

$\underset{i=1}{\overset{n_c}{\Σ}}{x}_{ij}=1$

The embodiment of the present invention, by obtaining the minima of year comprehensive method of investment cost, determines the quantity of quick charge stake, joint About cost；It addition, use aforementioned four constraints, retrain quick charge stake arranges quantity, so that quick charge stake Be arranged on and meet actual demand while, decrease Financial cost, thus reduce the cost that quick charge stake is set.

The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art For, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications are also considered as Protection scope of the present invention.
