Description

Technical Field

[0002] With the development of economy and society and the improvement of people's living standards, the demand for electricity continues to rise, especially during the high temperature period in summer. Excessive load pressure poses a challenge to the safe and stable operation of the power grid. In order to alleviate the pressure on the power grid and improve the flexibility and efficiency of the power system, demand response scheduling came into being. It refers to the voluntary adjustment of the time pattern of its power consumption demand by power users or power load management systems according to power supply conditions, electricity price signals or other incentives to achieve the optimal balance of power supply and demand. Through reasonable scheduling strategies, users can be guided to adjust their air conditioning usage behavior, reduce the power load during peak hours, and achieve a balance between power supply and demand without affecting user comfort.

[0003] Existing technologies only consider the power adjustment constraints, benefits and temperature comfort of the current user when solving the power adjustment value of the user's air conditioner, without considering the differences in the willingness of different users to participate in power adjustment. Even for users with the same objective conditions, their response willingness is different, and their execution of the same power adjustment value is also different, resulting in large scheduling deviations.

[0055] Figure 2 It is a structural diagram of an air conditioning demand response scheduling system taking into account user response willingness provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0056] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] like Figure 1 As shown, an air conditioning demand response scheduling method considering user response willingness is provided in one embodiment of the present invention, comprising:

[0058] Step S101: obtaining the air conditioning scheduling parameters of the current scheduling period, the temperature parameters at the beginning of the current scheduling period, and the historical cumulative response accuracy of the previous scheduling period; wherein the air conditioning scheduling parameters include: total scheduling power value, electricity price, unit incentive income, actual duration of unit period, user response willingness probability value, maximum operating power and minimum operating power; the temperature parameters include: indoor temperature, outdoor temperature, thermal resistance of indoor temperature change, and thermal capacity of outdoor temperature change; the historical cumulative response accuracy of the previous scheduling period is calculated by the demand response terminal device according to the actual air conditioning operating power at the beginning of the current scheduling period, the actual air conditioning operating power at the beginning of the previous scheduling period, and the air conditioning scheduling power value of the previous scheduling period;

[0059] Specifically, a scheduling period is 0.25h. The above user response willingness probability value ranges from 0 to 1. At the beginning of scheduling, the user can set it in the demand response terminal device according to his own situation. During the scheduling process, the user can also modify the set user response willingness probability value.

[0060] In a preferred embodiment, the historical cumulative response accuracy of the previous scheduling period is calculated based on the actual air conditioning operating power at the beginning of the current scheduling period, the actual air conditioning operating power at the beginning of the previous scheduling period, and the air conditioning scheduling power value of the previous scheduling period, including:

[0061] The response accuracy of the previous scheduling period is calculated based on the actual air conditioning operating power at the beginning of the current scheduling period, the actual air conditioning operating power at the beginning of the previous scheduling period, and the air conditioning scheduling power value of the previous scheduling period;

[0062] Specifically, the response accuracy of the previous scheduling period is calculated according to the following formula:

[0063]

[0064] In the formula, A ccn,t-1 represents the response accuracy of the nth air conditioner in the previous scheduling period, p n,t-1represents the actual operating power of the nth air conditioner in the previous scheduling period, p n,t represents the actual air-conditioning operating power of the nth air-conditioner at the beginning of the current scheduling period t, ξ n,t-1 Indicates the air conditioning scheduling power value of the nth air conditioner in the previous scheduling period.

[0065] Specifically, the response accuracy of the previous scheduling period is calculated starting from the second scheduling period. The response accuracy is a value in the range of 0 to 1.

[0066] According to the response accuracy rate of the previous scheduling period, the historical cumulative response accuracy rate of the previous scheduling period is calculated.

[0067] Specifically, the historical cumulative response accuracy rate of the previous scheduling period is calculated according to the following formula:

[0068]

[0069] Where, T n,t-1 represents the historical cumulative response accuracy of the nth air conditioner in the previous scheduling period, φ1 represents the attenuation coefficient, T n,t-2 Indicates the historical cumulative response accuracy of the nth air conditioner in the previous scheduling period.

[0070] Specifically, if the current scheduling period is the second scheduling period, the response accuracy of the first scheduling period is used as the historical cumulative response accuracy of the previous scheduling period; if the current scheduling period is the scheduling period after the second scheduling period, the historical cumulative response accuracy of the previous scheduling period is calculated based on the response accuracy of the previous scheduling period and the historical cumulative response accuracy of the previous scheduling period.

[0071] In this preferred embodiment, the historical cumulative response accuracy of the previous scheduling period is calculated based on the actual air conditioning operating power at the beginning of the current scheduling period, the actual air conditioning operating power at the beginning of the previous scheduling period, and the air conditioning scheduling power value of the previous scheduling period.

[0072] Step S102: Based on the air conditioning scheduling parameters of the current scheduling period, the temperature parameters at the beginning of the current scheduling period, and the historical cumulative response accuracy of the previous scheduling period, a demand response scheduling model and constraints of the demand response scheduling model are constructed with the goal of maximizing the benefits obtained by users participating in the scheduling and minimizing the user's room temperature dissatisfaction; wherein the constraints include: room temperature constraints, operating power constraints, and total scheduling response constraints;

[0073] In a preferred embodiment, the objective function of the above demand response scheduling model is:

[0074] W n,t=(c t +π t )·ξ n,t ·Δt

[0075] S n,t =(θ n,t,end -26) 2

[0076]

[0077] p n,t,rum =p n,t -ξ n,t

[0078] θ n,t,end =α n θ n,t,in +(1-α n )(θ n,t,out -R n p n,t,rum )

[0079]

[0080] Where W n,t represents the user economic value of the nth air conditioner in the current scheduling period t, c t represents the electricity price in the current dispatch period t, π t represents the unit incentive income in the current scheduling period t, Δt represents the actual duration of the current scheduling period t, which is 0.25h, S n,t represents the room temperature dissatisfaction corresponding to the nth air conditioner in the current scheduling period t, θ n,t,end It indicates the indoor temperature of the nth air conditioner at the end of the current scheduling period t, assuming that the user strictly follows the air conditioning scheduling power value of the current scheduling period. n represents the inertia coefficient of the nth air conditioner, R n represents the thermal resistance corresponding to the nth air conditioner, C n represents the heat capacity corresponding to the nth air conditioner, p n,t,rum It means that if the user strictly follows the air conditioning scheduling power value of the current scheduling period, the air conditioning operating power of the nth air conditioner in the current scheduling period t, p n,t represents the actual operating power of the nth air conditioner in the current scheduling period t, ξ n,t represents the air conditioning scheduling power value of the nth air conditioner in the current scheduling period t, θ n,t,in represents the indoor temperature corresponding to the nth air conditioner at the beginning of the current scheduling period t, θ n,t,out represents the outdoor temperature corresponding to the nth air conditioner at the beginning of the current scheduling period t, N represents the total number of air conditioners to be scheduled, and h n,trepresents the user credibility corresponding to the nth air conditioner in the current scheduling period t, ρ n,t represents the probability value of the user's response willingness of the nth air conditioner in the current scheduling period t, T n,t-1 represents the historical cumulative response accuracy of the nth air conditioner in the previous scheduling period, Represents the weight coefficient between the probability value of user response willingness and the historical cumulative response accuracy rate of the previous scheduling period.

[0081] Specifically, the objective function takes into account the benefits obtained by users through participating in the response, that is, the user economic value, and also takes into account the room temperature dissatisfaction. The user economic value is composed of the electricity cost saved by participating in the response, that is, the electricity price, and the incentive compensation income obtained, that is, the unit incentive income; the room temperature dissatisfaction is the deviation of the indoor temperature from the optimal temperature of 26 degrees Celsius at the end of the current scheduling period, assuming that the user performs the air conditioning scheduling work completely according to the air conditioning scheduling power value.

[0082] Specifically, users with higher user credibility are more reliable in performing response tasks. Therefore, they are considered to attach more importance to the benefits of participating in the response when making response decisions. Users with lower user credibility attach more importance to the indoor temperature comfort. Under this setting, even if all other parameters of the two air conditioners are the same, the amount of response tasks allocated to users with higher user credibility will be higher than that of users with lower user credibility. Based on this, the objective function of the above demand response scheduling model is constructed.

[0083] Specifically, the objective function of the above-mentioned demand response scheduling model aims to maximize the benefits obtained by users through participating in the response while minimizing users' dissatisfaction. In addition, the evaluated user credibility is taken into account in the objective function in a weighted manner to represent the differences in the degree of importance different users attach to economy and room temperature dissatisfaction.

[0084] In this preferred embodiment, an objective function of a demand response scheduling model is constructed.

[0085] In another preferred embodiment, the room temperature constraint is:

[0086] 24.8≤θ n,t,end ≤27.3

[0087] The above operating power constraints are:

[0088] p min ≤p n,t -ξ n,t ≤p max

[0089] The above total dispatch response constraint is:

[0090]

[0091] In the formula, p min Indicates the minimum operating power, p max Indicates the maximum operating power, f t represents the total scheduling power value of the current scheduling period t, φ3 represents the acceptable error coefficient, and its value range is between 0 and 1.

[0092] Specifically, the sum of the dispatch power values ​​of the air conditioners dispatched in each dispatch period should try to complete the total dispatch power value issued by the power grid at the beginning of the dispatch period, so as to obtain the above-mentioned total dispatch response constraint. The left side of the above-mentioned total dispatch response constraint is given in absolute value, which takes into account the positive and negative deviations of the error, and the right side takes into account that when an increase is required, the total dispatch power value is a negative value. If the above-mentioned total dispatch response constraint cannot be met, it means that the total dispatch power value at this time exceeds the cumulative adjustable range of the participating air conditioners, and the total dispatch power value should be reset.

[0093] Specifically, the acceptable range of indoor temperature for human body refers to the following PMV formula:

[0094]

[0095] In the formula, I PMV represents the mean thermal sensation index, and θ represents temperature.

[0096] Specifically, it is usually considered that I PMV When it is less than 0.5, the corresponding temperature is the human comfort temperature. Therefore, after calculation with the above formula, it can be obtained that the human comfort temperature is in the range of 24.8℃ to 27.3℃, thus obtaining the above room temperature constraint. The above room temperature constraint indicates that if the user strictly schedules the air conditioner according to the air conditioner scheduling power value of the current scheduling period, then at the end of the scheduling period, the indoor temperature should meet the above room temperature constraint.

[0097] Step S103: Calculate a first indoor temperature range according to the maximum operating power, the minimum operating power and the temperature parameter, and compare the first indoor temperature range with the room temperature constraint;

[0098] Specifically, this step is actually to substitute the above maximum operating power, minimum operating power and temperature parameters into the following formula:

[0099] θ′ n,t,end =α n θ n,t,in +(1-α n )(θ n,t,out -R n p n,t,rum )

[0100] pn,t,rum =p n,t -ξ n,t

[0101]

[0102] p min ≤p n,t -ξ n,t ≤p max

[0103] Specifically, the θ′ obtained after calculation n,t,end The value of is used as the first indoor temperature to determine whether the indoor temperature meets the room temperature constraint. According to the comparison result, it is determined whether the actual operating power range of the current air conditioner after participating in the scheduling can make the indoor temperature meet the comfort range corresponding to the room temperature constraint.

[0104] Step S104: When the first indoor temperature range meets the room temperature constraints, the demand response scheduling model is solved under the constraints to obtain the air conditioning scheduling power value of each air conditioner in the current scheduling period when the benefit is maximized and the room temperature dissatisfaction is minimized, and the air conditioning scheduling power value is sent to the demand response terminal device, so that the demand response terminal device schedules the operating power of each air conditioner according to the air conditioning scheduling power value.

[0105] Specifically, if the first indoor temperature range meets the room temperature constraint, it indicates that the air conditioner can make the indoor temperature meet the comfort range corresponding to the room temperature constraint within the actual operating power range after participating in the scheduling.

[0106] Specifically, the above constraints are all quadratic programming problems with linear constraints. n,t Expressed as a vector form ξ, the above objective function and the above constraints are transformed into a quadratic form as shown in the following formula:

[0107]

[0108] Wherein, P, Q, G, H, A and B all represent the transformed matrices.

[0109] Specifically, the quadratic objective function and constraints are solved on Python through the qp solver in cvxopt to obtain the air conditioning scheduling power value of each air conditioner in the current scheduling period when the above-mentioned benefit is maximized and the above-mentioned room temperature dissatisfaction is minimized.

[0110] In this preferred embodiment, the above-mentioned demand response scheduling model is solved under the above-mentioned constraints to obtain the air-conditioning scheduling power value of each air-conditioner in the current scheduling period when the above-mentioned benefit is maximized and the above-mentioned room temperature dissatisfaction is minimized, and the obtained air-conditioning scheduling power value is sent to the demand response terminal device to adjust the corresponding operating power of each air-conditioner.

[0111] In another preferred embodiment, it also includes:

[0112] In the case where the first indoor temperature range does not meet the room temperature constraint;

[0113] The air conditioner whose first indoor temperature range does not meet the room temperature constraint is used as the target air conditioner, and the air conditioner scheduling power value corresponding to the target air conditioner is set to 0;

[0114] The demand response scheduling model is solved under the above constraints to obtain the air conditioning scheduling power values ​​of the air conditioners other than the target air conditioner in the current scheduling period when the above benefit is maximized and the above room temperature dissatisfaction is minimized, and the air conditioning scheduling power values ​​are sent to the demand response terminal device, so that the demand response terminal device schedules the operating power of each air conditioner according to the air conditioning scheduling power values.

[0115] Specifically, if the first indoor temperature range does not meet the room temperature constraint, it means that after the air conditioner is scheduled, the actual operating power range cannot make the indoor temperature meet the comfort range corresponding to the room temperature constraint. At this time, these air conditioners that do not meet the room temperature constraint are no longer scheduled.

[0116] In this preferred embodiment, when the first indoor temperature range does not meet the room temperature constraint, the air conditioning scheduling power value of the target air conditioner is set to 0, and the above-mentioned demand response scheduling model is solved under the above-mentioned constraints to obtain the air conditioning scheduling power values ​​of the remaining air conditioners except the target air conditioner in the current scheduling period, and the air conditioning scheduling power values ​​are sent to the demand response terminal device together with the air conditioning scheduling power values ​​for power scheduling.

[0117] In another preferred embodiment, after the demand response terminal device schedules the operating power of each air conditioner according to the air conditioner scheduling power value, it also includes:

[0118] Obtain the operating power of each air conditioner in the current scheduling period after scheduling;

[0119] The operating power of the current scheduling period and the air conditioning scheduling power value of the current scheduling period are stored.

[0120] Specifically, after scheduling the operating power of the corresponding air conditioner according to the air conditioner scheduling power value, the demand response terminal stores the air conditioner scheduling power value of the current scheduling period and the operating power of the air conditioner corresponding to the current scheduling period after scheduling.

[0121] In this preferred embodiment, after scheduling the operating power of each air conditioner, the demand response terminal device also stores the air conditioner scheduling power value corresponding to the current scheduling period of each air conditioner and the operating power of the air conditioner after scheduling.

[0122] Based on the above method embodiment, the present invention provides a corresponding device embodiment;
