Wherein: K _i,nthe comfort level index of i-th air-conditioning in the n-th period; T _i,nthe indoor temperature of i-th air-conditioning in the n-th period; T _{i, set}it is the air-conditioner temperature setting value of i-th air-conditioning; Δ T _{i, set}be the air-conditioner temperature domain of walker of i-th air-conditioning, namely indoor temperature allowed band is T _{i, set}~ T _{i, set}+ Δ T _{i, set};

3.2 set up corresponding air conditioner load Controlling model

Assuming that air-conditioning work is in refrigeration mode, running state of air conditioner sets relevant with room temperature.When room temperature is higher than peak, air-conditioning is energized; During lower than minimum, air-conditioning power-off; When being in setting range, air-conditioning keeps original state.Its Controlling model is as follows:

$S_{i,n}=\left\{\begin{array}{cc}0& T_{i.n}\&le;T_{i,set}\\ 1& T_{i.n}\&GreaterEqual;T_{i,set}+{\mathrm{\&Delta;T}}_{i,set}\\ S_{i,n-1}& T_{i,set}<T_{i.n}<T_{i,set}+{\mathrm{\&Delta;T}}_{i,set}\end{array}\right.---\left(2\right)$

Wherein: S _i,nthat the air-conditioning of i-th air-conditioning within the n-th period cut-offs state, S _{i, n-1}that the air-conditioning of i-th air-conditioning within the (n-1)th period cut-offs state.

The equation that indoor temperature change generated in case changes with air-conditioning state is:

$\begin{array}{c}{T}_{i,n+1}=T_{n+1}^{out}-{\mathrm{\&eta;P}}_i{S}_{i,n+1}/A-(T_{n+1}^{out}-{\mathrm{\&eta;P}}_i{S}_{i,n+1}/A-T_{i,n})\mathrm{\&epsiv;}\\ =T_{n+1}^{out}-0.7(T_{n+1}^{out}-T_{i,n})-3.09S_{i,n+1}\end{array}---\left(3\right)$

Wherein: T _i.n+1the indoor temperature of i-th air-conditioning in the (n+1)th period; it is the outdoor temperature in the (n+1)th period; for the power of t air-conditioning; S _{i, n+1}cut-offfing state for air-conditioning, be 1 shutoff is 0 during unlatching; P _i5 air-conditionings are all defaulted as 2.5kW, P in calculating here by specified refrigeration consumed power when being i-th air-conditioning unlatching _is _{i, n+1}the actual power of i-th air-conditioning in the (n+1)th period; η is air-conditioning Energy Efficiency Ratio, is 2.8; A is thermal conductivity factor, unit be 1/ (kW DEG C-1), get 0.68; ε is heat radiation function, Δ t is control time interval, is decided to be 15min, T _cfor time constant, ε gets 0.70.

(4) the electricity consumption comfort level index of air-conditioning and the air conditioner load state of correspondence is calculated according to real data

Actually state S is cut-off according to each air-conditioning response start time _{i, 1}and indoor temperature T _{i, 1}, calculate the electricity consumption comfort level index K of i-th air-conditioning within N number of period _{i, 1}..., K _i,N, air-conditioning cut-offs state S _{i, 1}..., S _i,N, indoor temperature T _{i, 1}..., T _i,N, wherein i ∈ I.

Due to T _1,1=28.2 > (T _{1, set}+ Δ T _{1, set}), therefore the 1st period airconditioning control state is still for opening S _1,2=1;

According to the equation that indoor temperature change generated in case changes with air-conditioning state the indoor temperature that can calculate in the 1st period is T _1,2=26.91,

The electricity consumption comfort level index of the 1st period $K_{1,1}=\frac{|26.91-26|}{1.5}=\mathrm{0.601.}$

In like manner other several air-conditionings are calculated, the initial interrupt scheme of the 1st period can be obtained: namely in the 1st period, I platform air-conditioning cut-off state:

(5) each comfort level index is sorted by size, determine the interrupt scheme of final air-conditioning in conjunction with air conditioner load peak clipping total amount

Initial interrupt scheme only considers the electricity consumption comfort level of user in response process, does not consider whether the program can reach expection peak clipping effect, reaching peak clipping target, also needing to carry out the interrupt scheme optimization based on interrupt priority level for realizing each period:

5.1 calculate the n-th period initial interrupt scheme corresponding peak clipping amount judge whether to meet if do not meet, perform step 5.2, if meet, perform step 5.5;

In 5.2 n-th periods of screening, S _i,nthe air-conditioning of=1, is namely in the air conditioner load of opening in this period, its corresponding electricity consumption comfort level index is K _i,n ⁽¹⁾=K _i,n, and the electricity consumption comfort level index of these air conditioner loads sorted from big to small, comfort level desired value is larger, shows that user satisfaction is higher, mutually should the electricity consumption priority of air-conditioning lower, its interrupt priority level participating in demand response is then higher;

Suppose have X platform air-conditioning to be in opening in the n-th period, be followed successively by after descending sequence:

K _1,n ⁽¹⁾,K _2,n ⁽¹⁾,...,K _x,n ⁽¹⁾,...,K _X,n ⁽¹⁾。

5.3 because be in K in the air conditioner load of unlatching in the n period _{1, n} ⁽¹⁾corresponding air conditioning electricity satisfaction is the highest, and interrupt priority level is also the highest, therefore by K _{1, n} ⁽¹⁾corresponding air conditioner load cut-offs state S _i,nbe set to 0, namely become shutoff from unlatching, by S _i,nsubstitution formula (4) obtains the n-th period new interrupt scheme S _n;

5.4 calculate peak clipping amount P corresponding to new scheme _n, judge whether it meets P _n>=P _{aim, n}if discontented foot repeats step 5.2 to 5.3, if meet, perform step 5.5;

5.5 export the n-th period interrupt scheme;

5.6 interrupt scheme repeating for 1 ~ N number of period calculate, and can obtain the total interrupt scheme in the overall response period:

$S=(S_1,\mathrm{...}{S}_i,\mathrm{....}{S}_I)=\left[\begin{array}{ccccc}{S}_{1,1}& \mathrm{...}& S_{1,n}& \mathrm{...}& S_{1,N}\\ .& .& .& .& .\\ .& .& .& .& .\\ .& .& .& .& .\\ S_{i,1}& \mathrm{...}& S_{i,n}& \mathrm{...}& S_{i,N}\\ .& .& .& .& .\\ .& .& .& .& .\\ .& .& .& .& .\\ S_{I,1}& \mathrm{...}& S_{I,n}& \mathrm{...}& S_{I.N}\end{array}\right]---\left(5\right)$

$S=(S_1,...S_i,...S_I)=\left[\begin{array}{ccccc}{S}_{1,1}& ...& S_{1,n}& ...& S_{1,N}\\ \begin{array}{c}.\\ .\\ .\end{array}& \begin{array}{c}.\\ .\\ .\end{array}& \begin{array}{c}.\\ .\\ .\end{array}& \begin{array}{c}.\\ .\\ .\end{array}& \begin{array}{c}.\\ .\\ .\end{array}\\ S_{i,1}& ...& S_{i,n}& ...& S_{i,N}\\ \begin{array}{c}.\\ .\\ .\end{array}& \begin{array}{c}.\\ .\\ .\end{array}& \begin{array}{c}.\\ .\\ .\end{array}& \begin{array}{c}.\\ .\\ .\end{array}& \begin{array}{c}.\\ .\\ .\end{array}\\ S_{I,1}& ...& S_{I,n}& ...& S_{I.N}\end{array}\right]---\left(5\right)$

Namely the overall response scheme in day part in I platform air-conditioning N number of period is obtained.

2. method according to claim 1, is characterized in that, in formula (3), air-conditioning Energy Efficiency Ratio η value is 2.8; Thermal conductivity factor A value is 0.68; Heat radiation function ε value is 0.70, and control time interval value is 15min.
