Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air-conditioning load regulation, and particularly relates to a quantization system and method for air conditioners to participate in power grid regulation based on an intelligent optimization algorithm. Background Art
[0002] With the growth of the demand for flexible load regulation in the power system, air-conditioning load has become an important object of power grid demand-side management due to its strong adjustability and fast response speed. In the prior art, the research on air conditioners participating in power grid regulation mainly focuses on directions such as load aggregation control and price incentive response, but there are still the following limitations:
[0003] Most existing solutions regard users as a homogeneous group and do not distinguish the significant differences in temperature sensitivity and economic behavior patterns among residential, commercial, and industrial users. For example, residential users are more concerned about comfort costs, while industrial users need to consider production equipment losses. Due to the lack of classification and quantification indicators in existing models, the regulation strategies are mismatched with the actual user needs. Traditional methods only take electricity cost savings or subsidy benefits as the optimization goal, ignoring the implicit costs of air conditioners participating in regulation and the comprehensive benefits on the power grid side. The one-sidedness of the model easily leads to low user participation willingness and long-term economic imbalance of the power grid. Most existing load reduction algorithms only adopt a single total load capacity constraint and do not limit the adjustable capacity of different user types, which may cause the load reduction of a certain type of user to exceed the limit, resulting in an infeasible regulation scheme.
[0004] The above problems make it difficult for the prior art to balance the interests of users and the power grid, restricting the application potential of large-scale participation of air-conditioning load in power grid regulation. Summary of the Invention

[0155] For residential users, by weighting the square of the deviation between the outdoor temperature and the human neutral temperature in each time period, and combining the temperature influence time length and the monetization coefficient of residential comfort, the economic cost B f,1 generated by residential users due to temperature discomfort is obtained. The formula is expressed as:
[0156]
[0157] Where α is the monetization coefficient of residents' comfort, which is used to convert temperature deviation into economic loss; s is the time weight coefficient, which is used to reflect the difference in the impact of temperature deviation in different periods; T out is the outdoor temperature; T s is the neutral temperature of the human body; Δt is the temperature influence time length;
[0158] For commercial users, including production service commercial users and reception service commercial users, production service commercial users include office buildings, and reception service commercial users include shopping malls, hotels and restaurants; among them, for production service commercial users, the loss of work efficiency of staff caused by temperature change is calculated through the work efficiency function of production service commercial user staff, and combined with the economic output value of staff and the temperature influence time length, the economic cost B caused by temperature discomfort of production service commercial users is obtained f,2 For reception service commercial users, the percentage of dissatisfaction of guests received by reception service commercial users caused by temperature change is calculated, and combined with the turnover of staff, the economic cost B caused by temperature discomfort of reception service commercial users is obtained f,3 The formula is as follows:

[0163] For industrial users, by calculating the production capacity loss and equipment life loss caused by temperature change, and combining with the temperature influence time length, the economic cost B caused by temperature discomfort for industrial users is obtained f,4 , and the calculation formula is as follows:
[0164]
[0165] In the formula, γ prod is the economic coefficient affected by the production process, reflecting the influence of temperature change on production efficiency; ΔP t is the production capacity loss caused by temperature change at time t; γ equip is the economic coefficient of equipment loss, reflecting the influence of temperature change on equipment life; ΔD t is the additional equipment loss rate caused by temperature change at time t;
[0166] The depreciation cost of the air conditioner participating in power grid regulation is obtained by dividing the initial cost of the air conditioner by the depreciation life and then subtracting the air conditioner maintenance cost, and the formula is expressed as:
[0167]
[0168] In the formula, B N,i is the depreciation cost of the air conditioner of the i-th type of user participating in power grid regulation; n is the depreciation life of the air conditioner; M w,i is the maintenance cost of the air conditioner of the i-th type of user; M t,i is the initial cost of the air conditioner of the i-th type of user. The initial cost is the sum of all upfront investment costs before the air conditioner system is put into use, covering equipment purchase, installation and commissioning, and related supporting costs;
[0169] The installation and transformation cost of the air conditioner participating in power grid regulation is obtained by multiplying the power of the air conditioner to be transformed by the transformation cost per unit power, and the formula is expressed as:
[0170] B d,i =P f,i ×S f,i
[0171] In the formula, B d,iis the installation and retrofit cost for the air conditioner of the i-th type of user to participate in power grid regulation; P f,i is the load capacity of the air conditioner of the i-th type of user for installation or retrofit of the air conditioner; S f,i is the unit load installation and retrofit cost of the air conditioner of the i-th type of user.
[0172] The usage benefit is obtained by multiplying the sum of the subsidy per unit load of the air conditioner participating in power grid regulation and the electricity cost per unit load by the load reduction amount of the air conditioner participating in power grid regulation. The formula is expressed as follows:
[0173] C m,i = ΔR f,i (L C,i + M C,i )

[0175] The commercial users are subdivided into production service type (office buildings) and reception service type (shopping malls, hotels), and the economic cost calculation logics are designed respectively: the impact of temperature on the economic output of production service type commercial users is quantified through work efficiency loss, and the turnover loss of reception service type commercial users caused by temperature is quantified through customer dissatisfaction, solving the problem of regulation strategy deviation caused by the coarse-grained division of commercial user types in the prior art. The comfort cost, depreciation cost, and installation and retrofit cost are introduced to comprehensively cover the implicit costs of users participating in regulation, avoiding the overestimation of user benefits caused by cost omission in traditional models. When calculating the usage benefit of users' air conditioners, the electricity cost savings benefit and the demand response subsidy benefit are integrated to improve users' willingness to participate through economic incentives, solving the problem of insufficient attractiveness of the traditional single electricity price incentive model.
[0176] (2) In the grid regulation cost and benefit model construction module, according to the construction cost of the air conditioner load management platform generated by the air conditioner users participating in grid regulation for the grid, and the benefit of the grid saving operation cost when the air conditioner users participate in grid regulation compared with when the air conditioner users do not participate in grid regulation, the specific method for establishing the grid regulation cost and benefit model is as follows:
[0177] The costs in the grid regulation cost and benefit model include the construction cost of the air conditioner load management platform of the grid, and the benefits in the grid regulation cost and benefit model include the saved power generation capacity cost for peak shaving, the saved power generation fuel cost, the saved transmission and distribution cost, the saved new power generation capacity cost, and the saved carbon dioxide emission cost;
[0178] The construction cost of the air-conditioning load management platform for the power grid is obtained by multiplying the air-conditioning load connected to the air-conditioning load management platform by the construction cost of the air-conditioning load management platform per unit of air-conditioning load. The specific formula is as follows:
[0179] B r,i =P y,i ×S y,i
[0180] In the formula, B r,i is the construction cost of the air-conditioning load management platform for the power grid of the i-th type of user, P y is the air-conditioning load connected to the air-conditioning load management platform of the i-th type of user; S y is the construction cost of the air-conditioning load management platform per unit of air-conditioning load of the i-th type of user. Clearly incorporating the construction cost of the air-conditioning load management platform into the power grid regulation cost quantifies the upfront investment on the power grid side (such as equipment access and system setup), addressing the loophole in traditional models that only focus on the user-side cost while ignoring the investment in power grid infrastructure.
[0181] The saved power generation capacity cost for peak shaving refers to the regulation capacity of the coal-fired units originally used for peak shaving being replaced by air conditioners participating in power grid regulation, thus saving the operation and maintenance costs of the coal-fired units. The annual savings cost is obtained by multiplying the annual operation and maintenance cost per unit power of the coal-fired units by the load reduction amount of the air conditioners due to participating in power grid regulation, and then the annual savings cost is converted into the total present value of the full cycle through the present value factor of the annuity. The formula is expressed as:
[0182]
[0183] In the formula, C f,i is the saved power generation capacity cost for peak shaving of the i-th type of user, C hdo,i is the annual operation and maintenance cost per unit power of the coal-fired units for peak shaving due to the i-th type of user; P i is the actual regulation power provided by the air conditioners of the i-th type of user when participating in power grid peak shaving; (A, i 0,i , T) i is the present value factor of the annuity of the i-th type of user, representing the present value conversion factor of the unit cash flow under the discount rate i 0,i and the time period T of the i-th type of user;
[0184] The saved transmission and distribution cost refers to the investment cost of the power grid capacity reduced due to load transfer after the air conditioners participate in power grid regulation. It is obtained by multiplying the load reduction amount of the air conditioners due to participating in power grid regulation by the investment cost per unit capacity of the power grid. The formula is expressed as:
[0185]
[0186] In the formula, C d,iis the power transmission and distribution cost saved by the i-th type of user, C z is the total investment cost of the power grid; R z is the total capacity of the power grid;
[0187] The saved power generation fuel cost refers to the fuel cost saved due to the reduction in power consumption after the air conditioner participates in power grid regulation. It is obtained by multiplying the reduced power consumption after the air conditioner participates in power grid regulation by the marginal fuel cost per unit of power. The formula is expressed as:
[0188] C r,i = ΔL i × AC
[0189] In the formula, C r,i is the power generation fuel cost saved by the i-th type of user, ΔL i is the reduced power consumption of the air conditioner of the i-th type of user after participating in power grid regulation; AC is the marginal fuel cost per unit of power, which is dynamically adjusted according to market fluctuations, enabling the model to adapt to fuel price changes and enhancing the robustness of the regulation strategy;
[0190] The saved cost of new power generation capacity refers to the reduction in the peak load of the power grid through peak-shaving power consumption after the air conditioner participates in power grid regulation, thereby replacing the corresponding installed capacity and reducing the cost of new units. It usually depends on the selection and scale of the reference power plant, investment cost, and other necessary fixed costs. It is obtained by multiplying the load reduction amount due to the air conditioner participating in power grid regulation by the investment cost per unit of new capacity of the power grid. The formula is expressed as:
[0191] C N,i = ΔR f,i × ΔC n
[0192] In the formula, C N,i is the cost of new power generation capacity saved by the i-th type of user, ΔC n is the investment cost per unit of new capacity of the power grid; The saved carbon dioxide emission cost is obtained by multiplying the unit carbon dioxide price by the carbon dioxide emission equivalent. The formula is expressed as:
[0193] C e,i = F C M C
[0194]
[0195] In the formula, C e,i is the carbon dioxide emission cost saved by the i-th type of user, F C is the unit price of carbon dioxide; M C is the carbon dioxide emission equivalent; ΔQ t,iThe electricity consumption reduced by the air conditioners of the i-th type of users within the time period t; B is the carbon emission intensity of coal-fired power units. It is used to make up for the neglect of environmental protection benefits in traditional models and help the power grid achieve the goal of low-carbonization.
[0196] Incorporate the savings in peak shaving capacity cost (maintenance cost of coal-fired power units × reduction amount), the savings in transmission and distribution investment (reduction amount × unit capacity cost), and the savings in carbon emission cost (reduction amount × carbon intensity × carbon price) to solve the problem that traditional models only focus on electricity revenue and ignore the long-term economy of the power grid. Convert the annual cost saved by peak shaving capacity into the present value of the full cycle through the present value factor of annuity, improve the scientific nature of power grid investment decisions, and avoid the drawbacks of traditional static models overestimating short-term revenue and underestimating long-term maintenance costs. At the same time, through the revenue-cost correlation of classified users (residential, commercial, industrial), dynamically reflect the contribution differences of different user types to power grid regulation (for example, industrial users have a larger load reduction and a higher contribution to the savings in peak shaving capacity).
[0197] (3) In the air-conditioning load reduction amount solving module, the specific method for solving the air-conditioning load reduction amount of air-conditioning users participating in power grid regulation by using the particle swarm algorithm according to the air-conditioning usage cost and revenue model to establish the objective function of maximizing the single-day profit of air-conditioning users' revenue and according to the air-conditioning usage cost and revenue model and the power grid regulation cost and revenue model to establish the constraint condition that the net profit of the power grid is greater than or equal to zero is as follows:
[0198] Establish the objective function based on the maximization of the profit of air-conditioning users in the power grid regulation area, and the formula is as follows:
[0199]
[0200] In the formula, k is the total number of air-conditioning user types in the power grid regulation area;
[0201] Establish the constraint condition based on the net profit of the power grid being greater than or equal to zero and the air-conditioning load at time t in the power grid regulation area being greater than the load reduction amount of air-conditioning participating in power grid regulation, and the formula is as follows:
[0202]
[0203] ΔR f,i ≤P t,i
[0204] In the formula, P t,i is the air-conditioning load of the i-th type of users at time t in the power grid regulation area.
[0205] The constraint condition requires that the net profit of the power grid ≥ 0 and the load reduction amount ≤ the load in the regulation area to ensure the sustainability of power grid regulation and avoid losses of the power grid caused by unilateral profit-making of users.
[0206] Express the particle position X as the solution vector of each user's load reduction amount, i.e., X = [ΔR1, ΔR2,..., ΔR n , and the velocity update formula is:
[0207] v j (t + 1) = w·v j (t) + c1r1(p best,j -X j (t)) + c2r2(g best -X j (t))X j (t + 1) = X j (t) + v j (t + 1)
[0208] In the formula, j represents the serial number of the particle; v j represents the velocity of the j-th particle; w is the inertia weight; c1 is the first learning factor; c2 is the second learning factor; p best,j is the individual historical optimal position of the j-th particle; g best is the global optimal position of the entire population, X j is the position of the j-th particle;
[0209] Convert the objective function into a fitness value and add a constraint penalty term:
[0210]
[0211] In the formula, λ is the penalty coefficient, which imposes a penalty on the solution with overloaded load, forcing the algorithm to search the feasible solution space and improving the practical operability of the optimization result;
[0212] Set the particle swarm size, maximum number of iterations, initial position and velocity range, calculate the fitness value of each particle, update the individual optimal p best,j and the global optimal g best , dynamically adjust the inertia weight w, and after updating the velocity v j and the position X j , correct the particles that exceed ΔR f,i ≤P t,i (boundary constraint processing, dynamic inertia weight adjustment, particle state reset), balance the global search and local convergence capabilities, and avoid the premature convergence problem of the traditional particle swarm algorithm. Use the particle swarm algorithm to solve high-dimensional nonlinear optimization problems and avoid falling into local optima.

[0242] The commercial users are subdivided into production service type (office building) and reception service type (shopping mall, hotel), and the economic cost calculation logics are designed respectively: the impact of temperature on the economic output of production service type commercial users is quantified through the loss of work efficiency, and the loss of turnover of reception service type commercial users caused by temperature is quantified through customer dissatisfaction, solving the problem of deviation of regulation strategies caused by the coarse-grained classification of commercial user types in the existing technology. The comfort cost, depreciation cost, and installation and transformation cost are introduced to comprehensively cover the hidden costs of users participating in regulation, avoiding the overestimation of user income caused by cost omission in traditional models. When calculating the usage income of users' air conditioners, the electricity cost savings income and the demand response subsidy income are integrated, and the user participation willingness is improved through economic incentives, solving the problem of insufficient attraction of the traditional single electricity price incentive model.
[0243] (2) The specific method for establishing the power grid regulation cost and income model based on the construction cost of the air conditioner load management platform generated by the air conditioner users participating in power grid regulation and the income of the power grid saved in operation cost when the air conditioner users participate in power grid regulation compared with when they do not participate in power grid regulation is as follows:
[0244] The costs in the power grid regulation cost and benefit model include the construction cost of the air-conditioning load management platform of the power grid. The benefits in the power grid regulation cost and benefit model include the saved power generation capacity cost for peak regulation, the saved power generation fuel cost, the saved transmission and distribution cost, the saved cost of newly built power generation capacity, and the saved carbon dioxide emission cost;
[0245] The construction cost of the air-conditioning load management platform of the power grid is obtained by multiplying the air-conditioning load connected to the air-conditioning load management platform by the construction cost of the air-conditioning load management platform per unit air-conditioning load. The specific formula is as follows:
[0246] B r,i =P y,i ×S y,i
[0247] In the formula, B r,i is the construction cost of the air-conditioning load management platform of the power grid for the i-th type of user, P y is the air-conditioning load connected to the air-conditioning load management platform for the i-th type of user; S y is the construction cost of the air-conditioning load management platform per unit air-conditioning load for the i-th type of user. Clearly incorporating the construction cost of the air-conditioning load management platform into the power grid regulation cost quantifies the upfront investment on the power grid side (such as equipment access and system setup), addressing the loophole in traditional models that only focus on user-side costs while ignoring power grid infrastructure investment.
[0248] The saved power generation capacity cost for peak regulation refers to the regulation capacity of the coal-fired units originally used for peak regulation being replaced by air conditioners participating in power grid regulation, thereby saving the operation and maintenance costs of the coal-fired units. The annual saved cost is obtained by multiplying the annual operation and maintenance cost per unit power of the coal-fired units by the load reduced by the air conditioners due to participating in power grid regulation, and then converting the annual saved cost into the total present value of the full cycle through the annuity present value factor. The formula is expressed as:
[0249]
[0250] In the formula, C f,i is the saved power generation capacity cost for peak regulation for the i-th type of user, C hdo,i is the annual operation and maintenance cost per unit power of the coal-fired units for peak regulation due to the i-th type of user; P i is the actual regulation power provided by the air conditioners of the i-th type of user when participating in power grid peak regulation; (A, i 0,i , T) i is the annuity present value factor for the i-th type of user, representing the present value conversion factor of the unit cash flow under the discount rate i 0,i and the time period T of the i-th type of user;
[0251] The saved power transmission and distribution cost refers to the investment cost of the grid capacity reduced due to load transfer after the air conditioner participates in grid regulation. It is obtained by multiplying the load reduction amount of the air conditioner due to participating in grid regulation by the investment cost per unit capacity of the grid, and is expressed by the formula:
[0252]
[0253] In the formula, C d,i is the saved power transmission and distribution cost of the i-th type of user, and C z is the total grid investment cost; R z is the total grid capacity;
[0254] The saved power generation fuel cost refers to the fuel cost saved due to the reduction in electricity consumption after the air conditioner participates in grid regulation. It is obtained by multiplying the reduced electricity consumption after the air conditioner participates in grid regulation by the marginal fuel cost per unit of electricity, and is expressed by the formula:
[0255] C r,i =ΔL i ×AC
[0256] In the formula, C r,i is the saved power generation fuel cost of the i-th type of user, ΔL i is the reduced electricity consumption of the air conditioner of the i-th type of user after participating in grid regulation; AC is the marginal fuel cost per unit of electricity, which is dynamically adjusted according to market fluctuations, enabling the model to adapt to fuel price changes and enhancing the robustness of the regulation strategy;
[0257] The saved cost of new power generation capacity refers to the reduction in the peak load of the grid through off-peak electricity consumption after the air conditioner participates in grid regulation, thereby replacing the corresponding installed capacity and reducing the cost of new units. It usually depends on the selection and scale of the reference power plant, investment cost, and other necessary fixed costs. It is obtained by multiplying the load reduction amount of the air conditioner due to participating in grid regulation by the investment cost per unit of new grid capacity, and is expressed by the formula:
[0258] G N,i =ΔR f,i ×ΔC n
[0259] In the formula, C N,i is the saved cost of new power generation capacity of the i-th type of user, ΔC n is the investment cost per unit of new grid capacity; The saved carbon dioxide emission cost is obtained by multiplying the unit carbon dioxide price by the carbon dioxide emission equivalent, and is expressed by the formula:
[0260] C e,i =F C M C
[0261]
[0262] Wherein, C e,i is the carbon dioxide emission cost saved by the i-th type of user, F C is the unit price of carbon dioxide; M C is the carbon dioxide emission equivalent; ΔQ t,i is the electricity consumption reduced by the air conditioner of the i-th type of user during the time period t; B is the carbon emission intensity of the coal-fired unit. It is used to make up for the neglect of environmental protection benefits in the traditional model and help the power grid achieve the low-carbon goal.
[0263] Incorporate the peak shaving capacity cost savings (coal-fired unit operation and maintenance cost × reduction), transmission and distribution investment savings (reduction × unit capacity cost), and carbon emission cost savings (reduction × carbon intensity × carbon price) to solve the problem that the traditional model only focuses on electricity revenue and ignores the long-term economy of the power grid. The annual cost saved by peak shaving capacity is converted into the present value of the whole cycle through the present value factor of annuity, which improves the scientific nature of power grid investment decisions and avoids the disadvantages of the traditional static model of overestimating short-term benefits and underestimating long-term operation and maintenance costs. At the same time, through the income-cost correlation of classified users (residential, commercial, industrial), the contribution differences of different user types to power grid regulation are dynamically reflected (for example, industrial users have a larger load reduction and a higher contribution to peak shaving capacity savings).
[0264] (3) The specific method for solving the air-conditioning load reduction of air-conditioning users participating in power grid regulation by using the particle swarm algorithm according to the air-conditioning usage cost and revenue model to establish the objective function of maximizing the single-day profit of air-conditioning users' revenue and according to the air-conditioning usage cost and revenue model and the power grid regulation cost and revenue model to establish the constraint condition that the net profit of the power grid is greater than or equal to zero is as follows:
[0265] Establish the objective function based on the maximization of the profit of air-conditioning users in the power grid regulation area, and the formula is as follows:
[0266]
[0267] Wherein, k is the total number of air-conditioning user types in the power grid regulation area;
[0268] Establish the constraint condition that the net profit of the power grid is greater than or equal to zero and the air-conditioning load at time t in the power grid regulation area is greater than the load reduction of the air-conditioning participating in the power grid regulation, and the formula is as follows:
[0269]
[0270] ΔR f,i ≤P t,i
[0271] Wherein, P t,i is the air-conditioning load of the i-th type of user at time t in the power grid regulation area.
[0272] The constraint requires that the net profit of the power grid ≥ 0 and the load curtailment ≤ the load in the regulation area, ensuring the sustainability of power grid regulation and avoiding losses of the power grid caused by unilateral profit-making of users.
[0273] The particle position X is expressed as the solution vector of the load curtailment of each user, i.e., X = [ΔR1, ΔR2,..., ΔR n , and the velocity update formula is:
[0274] v j (t + 1) = w·v j (t) + c1r1(p best,j -X j (t)) + c2r2(g best -X j (t))X j (t + 1) = X j (t) + v j (t + 1)
[0275] In the formula, j represents the serial number of the particle; v j represents the velocity of the j-th particle; w is the inertia weight; c1 is the first learning factor; c2 is the second learning factor; p best,j is the individual historical optimal position of the j-th particle; g best is the global optimal position of the entire population, X j is the position of the j-th particle;
[0276] The objective function is transformed into a fitness value, and a constraint penalty term is added:
[0277]
[0278] In the formula, λ is the penalty coefficient, which imposes a penalty on the solution with over-limit load, forcing the algorithm to search the feasible solution space and improving the practical operability of the optimization result;
[0279] As Figure 2 shown, the particle swarm size, the maximum number of iterations, the initial position, and the velocity range are set, the fitness value of each particle is calculated, and the individual optimal p best,j and the global optimal g best are updated. The inertia weight w is dynamically adjusted. After the velocity v j and the position X j are updated, the particles exceeding ΔR f,i ≤P t,i are corrected (boundary constraint handling, dynamic inertia weight adjustment, particle state reset), balancing the global search and local convergence capabilities and avoiding the premature convergence problem of the traditional particle swarm algorithm. The particle swarm algorithm is used to solve high-dimensional non-linear optimization problems and avoid falling into local optima.
