(4) Calculate the power consumption comfort index of the air conditioner and the corresponding air conditioner load status according to the actual data:

According to the actual on-off state S _i,1 and the indoor temperature T _i,1 of each air conditioner at the beginning of the response, calculate the electricity comfort index K _i,1 ,...,K _{i, N} , air conditioner off state S _i,1 ,...,S _i,N , indoor temperature T _i,1 ,...,T _i,N ;

(5) Sort each comfort index according to size, and determine the final air-conditioning interruption plan in combination with the total amount of air-conditioning load shaving:

5.1 Calculate the initial outage scheme for the nth time period Corresponding amount of clipping Judging whether it is satisfied If it is not satisfied, go to step 5.2, if it is satisfied, go to step 5.5;

5.2 Screen the air conditioner with S _i,n = 1 in the nth period, that is, the air conditioner load that is turned on during this period, and its corresponding electric comfort index is The power consumption comfort index of these air-conditioning loads is sorted from large to small. The larger the comfort index value is, the higher the user satisfaction is, and the lower the power consumption priority of the air conditioner is, and the interruption priority of its participation in demand response is the higher the level;

Assuming that there are X air conditioners that are turned on in the nth time period, they are sorted from large to small as follows:

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

5.3 Because K _1,n ⁽¹⁾ corresponds to the highest air-conditioning power satisfaction and the highest interruption priority among the air-conditioning loads that are turned on during the n period, so the air-conditioning load corresponding to K _1,n ⁽¹⁾ is switched off in the state S _{i, n} are set to 0, that is, from on to off, and S _{i, n} are substituted into formula (4) to get the new interruption scheme S _n of the nth period;

5.4 Calculate the peak-shaving amount P _n corresponding to the new plan, and judge whether it satisfies P _{n ≥} Paim _,n , if not, repeat steps 5.2 to 5.3, and if it is satisfied, go to step 5.5;

5.5 Output the interruption scheme for the nth period;

5.6 Repeat the calculation of the interruption scheme for 1 to N periods, and the total interruption scheme in the total response period can be obtained:

Among them: S _i,n is the air conditioner off state of the i-th air conditioner in the nth time period, S _i,n-1 is the air conditioner off state of the i-th air conditioner in the n-1 time period.

Among them: T _i.n+1 is the indoor temperature of the i-th air conditioner in the n+1 period; is the outdoor temperature in the n+1th period; is the power of the air conditioner at time t; S _i,n+1 is the on-off state of the air conditioner, which is 1 when it is turned on and 0 when it is turned off; P _i is the rated cooling power consumption of the i-th air conditioner when it is turned on. Both default to 2.5kW, P _i S _i,n+1 is the actual power of the i-th air conditioner at the n+1 period; η is the energy efficiency ratio of the air conditioner, which is 2.8; A is the thermal conductivity, and the unit is 1/(kW· ℃-1), take 0.68; ε is the heat dissipation function, Δt is the control time interval, set as 15min, T _C is the time constant, ε is taken as 0.70.

(4) Calculate the power comfort index of the air conditioner and the corresponding air conditioner load status based on the actual data

According to the actual on-off state S _i,1 and the indoor temperature T _i,1 of each air conditioner at the beginning of the response, calculate the electricity comfort index K _i,1 ,...,K _{i, N} , air conditioner off-state S _i,1 ,...,S _i,N , indoor temperature T _i,1 ,...,T _i,N , where i∈I.

Take the first air conditioner in the first period as an example, before responding, S _1,0 = 1, T _1,0 = 28.2, Calculation of available electricity comfort index $K_{1,0}=\frac{|28.2-26|}{1.5}=1.467:$

Since T _1,1 =28.2>(T _1,set +ΔT _1,set ), the air conditioner control status is still on in the first period S _1,2 =1;

According to the equation that the indoor temperature changes with the state of the air conditioner It can be calculated that the indoor temperature in the first period is T _1,2 = 26.91,

Electricity comfort index in the first period $K_{1,1}=\frac{|26.91-26|}{1.5}=\mathrm{0.601.}$

Similarly, by calculating the other several air conditioners, the initial interruption scheme of the first period can be obtained: that is, the on-off state of the I air conditioner in the first period:

${\mathrm{<span\; class="notranslate">\; S</span>}}_{\mathrm{<span\; class="notranslate">\; 1</span>}}^{\mathrm{<span\; class="notranslate">\; 0</span>}}<span\; class="notranslate">\; =</span>{<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; S</span>}}_{\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; ...</span>}{\mathrm{<span\; class="notranslate">\; S</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; ...</span>}{\mathrm{<span\; class="notranslate">\; S</span>}}_{\mathrm{<span\; class="notranslate">\; I</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; )</span>}^{\mathrm{<span\; class="notranslate">\; T</span>}}<span\; class="notranslate">\; =</span>{\left[\begin{array}{ccccc}\mathrm{<span\; class="notranslate">\; 1</span>}& \mathrm{<span\; class="notranslate">\; 1</span>}& \mathrm{<span\; class="notranslate">\; 0</span>}& \mathrm{<span\; class="notranslate">\; 1</span>}& \mathrm{<span\; class="notranslate">\; 1</span>}\end{array}\right]}^{\mathrm{<span\; class="notranslate">\; T</span>}}<span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 4</span>}<span\; class="notranslate">\; )</span>$

(5) Sort each comfort index according to size, and determine the final air-conditioning interruption plan based on the total amount of air-conditioning load peak-shaving

The initial interruption scheme only considers the user's power consumption comfort during the response process, and does not consider whether the scheme can achieve the expected peak-shaving effect. In order to achieve the peak-shaving target at each time period, it is necessary to optimize the interruption scheme based on the interruption priority:

5.1 Calculate the initial outage scheme for the nth time period Corresponding amount of clipping Judging whether it is satisfied If it is not satisfied, go to step 5.2, if it is satisfied, go to step 5.5;

5.2 Screen the air conditioner with S _i,n =1 in the nth period, that is, the air conditioner load that is turned on during this period, and its corresponding electric comfort index is K _i,n ⁽¹⁾ =K _i,n , and The power consumption comfort index of these air-conditioning loads is sorted from large to small. The larger the comfort index value is, the higher the user satisfaction is, and the lower the power consumption priority of the air conditioner is, and the interruption priority of its participation in demand response is higher. higher;

Assuming that there are X air conditioners that are turned on in the nth time period, they are sorted from large to small as follows:

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

5.3 Because K _1,n ⁽¹⁾ corresponds to the highest air-conditioning power satisfaction and the highest interruption priority among the air-conditioning loads that are turned on during the n period, so the air-conditioning load corresponding to K _1,n ⁽¹⁾ is switched off in the state S _{i, n} are set to 0, that is, from on to off, and S _{i, n} are substituted into formula (4) to get the new interruption scheme S _n of the nth period;

5.4 Calculate the peak-shaving amount P _n corresponding to the new plan, and judge whether it satisfies P _{n ≥} Paim _,n , if not, repeat steps 5.2 to 5.3, and if so, perform step 5.5;

5.5 Output the interruption scheme for the nth period;

5.6 Repeat the calculation of the interruption scheme for 1 to N periods, and the total interruption scheme in the total response period can be obtained:
