Description

Technical Field

[0001] The present application relates to the technical field of power grid power management, and in particular to a method, device, equipment and storage medium for distributing power interruption loads. Background Art

[0002] When local power generation is low and external power transmission is insufficient, resulting in a low grid frequency, in order to avoid causing power outages on a larger scale, the power company implements sequenced power consumption or power outages. The total amount of interrupted load caused by power outages is mainly composed of the interruptible power consumption reported by electricity users.

[0003] However, due to the information asymmetry between power companies and users, users are not very active in participating in interruption load management. Power companies can only see relatively closed information within their own responsibilities, making it difficult to determine which users can participate in interruption load management, nor can they determine the accuracy of the interruptible power reported by users, resulting in inefficient interruption load management and irrational resource allocation. Summary of the Invention

[0004] The present application provides a method, device, equipment and storage medium for distributing power outage loads to solve the technical problem of unreasonable load distribution in existing power grids.

[0005] In order to solve the above technical problems, in a first aspect, an embodiment of the present application provides a method for distributing power interruption loads, comprising:

[0006] Obtain the total interrupted load of the power grid system and the user types of multiple electricity users;

[0007] Determine the power outage cost data and power outage compensation data for each electricity user based on the user type;

[0008] Generate a benefit function for each electricity user based on the power outage cost data and the power outage compensation data;

[0009] Using a preset optimal response solution algorithm, the total amount of interrupted load and the benefit function of each electricity user are iterated until the interruptible power of each electricity user meets the optimal benefit value of the corresponding benefit function, and the sum of the interruptible power of all electricity users is equal to the total amount of interrupted load. The iteration is stopped to obtain the interruptible power of each electricity user. The interruptible power is used by the power grid system to allocate the interruption power to the electricity user and to perform power-off operations on the electricity user.

[0010] This embodiment obtains the total interruption load of the power grid system and the user types of multiple electricity users, and determines the power outage cost data and power outage compensation data of each electricity user based on the user type, fully considering the user's willingness to interrupt power, so that the interruptible power of each user can be subsequently determined based on the power outage cost and power outage compensation, and users with low power outage costs can bear more interruptible power as much as possible; and generates a benefit function for each electricity user based on the power outage cost data and power outage compensation data, thereby considering each user's own benefits and improving the user's willingness to interrupt power, so as to make the interruption load distribution more fair and accurate; finally, using a preset optimal response solution algorithm, iterate the total interruption load and the benefit function of each electricity user until the interruptible power of each electricity user meets the optimal benefit value of the corresponding benefit function and the sum of the interruptible power of all electricity users is equal to the total interruption load. The iteration is stopped to obtain the interruptible power of each electricity user, so as to achieve reasonable resource allocation through computer analysis and improve the efficiency of interruption load distribution management.

[0013] Determine the power outage cost data for each electricity user based on user type parameters and power outage cost coefficient;

[0014] According to the power outage compensation electricity price, the power outage compensation data of each electricity user is determined.

[0015] This embodiment determines the power outage cost coefficient according to the user type to fully consider the user's willingness to power off, and provides power outage compensation to the user in combination with the power outage compensation electricity price, thereby increasing the user's willingness to take the initiative to power off and compensating for objective economic losses.

[0016] Optionally, determining power outage cost data for each electricity user based on the user type parameter and the power outage cost coefficient includes:

[0017] Using the preset power outage cost formula, the power outage cost data of each electricity user is determined according to the user type parameters and the power outage cost coefficient. The power outage cost formula is:

[0018] c(θ i , x i )=K1x i 2 +K2x i -K2θ i x i ;

[0019] where c(θi , x i ) represents the power outage cost data of the i-th electricity user, θ i represents the user type parameter of the i-th electricity user, x i represents the interruptible power quantity to be determined for the i-th electricity user, and K1 and K2 both represent the power outage cost coefficients.

[0020] In one embodiment, based on the power outage cost data and the power outage compensation data, a benefit function is generated for each electricity user, including:

[0021] Determine the electricity sharing cost data for each electricity user based on the total interrupted load;

[0022] Based on the power outage cost data, power outage compensation data and electricity sharing cost data, a benefit function for each electricity user is generated.

[0023] This embodiment introduces power sharing cost data to compensate for the operating costs caused by the grid needing to use backup power due to system shortages, making the entire ecological chain more reasonable.

[0024] Optionally, the benefit function is:

[0025] f(x i )=p ０ x i +p i x i -c(θ i , x i )-β(ΔL) 2 ;

[0026] β(ΔL) 2 =β(L-∑x i ) 2 ;

[0027] where f(x i ) represents the benefit function of the i-th electricity user, x i represents the interruptible power quantity to be determined by the i-th electricity user, p0 represents the electricity price, and p i x i represents the power outage compensation data of the i-th electricity user, p i The power outage compensation price for the i-th electricity user, c(θ i , x i ) represents the outage cost data of the i-th electricity user, β(ΔL) 2 represents the electricity sharing cost data of the i-th electricity user, β represents the electricity sharing cost parameter, and L represents the total interruption load.

[0028] In one embodiment, a preset optimal response solution algorithm is used to iterate the total interruption load and the benefit function of each electricity user until the interruptible power of each electricity user satisfies the optimal benefit value of the corresponding benefit function and the sum of the interruptible power of all electricity users is equal to the total interruption load. The iteration is stopped to obtain the interruptible power of each electricity user, including:

[0029] Using the optimal response solution algorithm, initialize the interruptible power decision value of the i-th electricity user and the total number of electricity users n;

[0030] For the i-th electricity user when the interruptible power decision value of other electricity users is included, according to the interruptible power decision value And the benefit function f(x i ), iteratively calculate the interruptible power of the i-th electricity user

[0031] make m=m+1, judge Is it not greater than the preset threshold ε? i ;

[0032] like Then stop the iterative calculation of the interruptible power consumption of the i-th electricity user;

[0033] Continue to iterate and calculate the interruptible power consumption of the i+1th electricity user Until n electricity users are satisfied And the total interruption load Get the interruptible power of each electricity user.

[0034] This embodiment considers the impact of other users' determined interruptible power on the i-th electricity user's interruptible power, so as to ensure that users with low power shortage costs bear more interruptible load while meeting the total interruptible load, so that the benefit functions of all users are balanced, thereby making resource allocation more reasonable.

[0035] Optionally, power can be interrupted The calculation formula is:

[0049] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] As documented in relevant technologies, due to information asymmetry between power companies and users, users are not very active in participating in interruption load management. Power companies can only see relatively closed information within their own responsibilities, making it difficult to identify users who can participate in interruption load management, nor can they determine the accuracy of the interruptible power reported by users, resulting in inefficient interruption load management.

[0051] To this end, embodiments of the present application provide a method, apparatus, device, and storage medium for allocating power interruption loads. The method obtains the total interruption load of the power grid system and the user types of multiple power users, and determines the power outage cost data and power outage compensation data of each power user based on the user type, fully considering the user's willingness to interrupt power, so that the interruptible power amount of each user can be subsequently determined based on the power outage cost and power outage compensation, and users with low power outage costs can bear more interruptible power as much as possible; and generates a benefit function for each power user based on the power outage cost data and power outage compensation data, thereby considering each user's own benefits and improving the user's willingness to interrupt power, so as to make the interruption load allocation more fair and accurate; finally, using a preset optimal response solution algorithm, iterate the total interruption load and the benefit function of each power user until the interruptible power amount of each power user meets the optimal benefit value of the corresponding benefit function and the sum of the interruptible power amounts of all power users is equal to the total interruption load. The iteration is stopped to obtain the interruptible power amount of each power user, so as to achieve reasonable resource allocation through computer analysis and improve the efficiency of interruption load distribution management.

[0052] Reference Figure 1 , Figure 1 The flow chart of a method for distributing power outage loads provided in an embodiment of the present application is as follows. The method for distributing power outage loads in an embodiment of the present application can be applied to computer devices, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, physical servers, cloud servers and other computing devices. Figure 1 As shown, the method for distributing power interruption loads includes steps S101 to S104, which are described in detail as follows:

[0053] Step S101: obtaining the total interrupted load of the power grid system and the user types of multiple electricity users (hereinafter referred to as users).

[0054] In this step, the total amount of interrupted load is the total amount of power cuts caused by the power grid system. User types include but are not limited to residential electricity users, commercial electricity users and industrial electricity users. Among them, commercial electricity users and industrial electricity users can be further divided into large-scale commercial electricity users, small-scale commercial electricity users, large-scale industrial electricity users and small-scale industrial electricity users according to actual electricity consumption and electricity demand.

[0055] It is understandable that different types of users have different willingness to have power outages. The less willing users are to have power outages, the higher their requirements for power supply reliability and the greater the corresponding power outage costs.

[0056] Step S102: determining power outage cost data and power outage compensation data for each of the electricity users according to the user type.

[0057] In this step, the outage cost data is the economic loss data caused by the power outage to the user, and the outage compensation data is the economic compensation data received by the user from the power grid company due to the power outage. It can be understood that the greater the user's interruptible power consumption, the greater the outage cost data and outage compensation data.

[0058] Optionally, a power outage cost parameter and a power outage compensation price are determined according to the user type; the user's power outage cost data is determined according to the power outage cost parameter; and the user's power outage compensation data is determined according to the power outage compensation price.

[0059] Step S103: generating a benefit function for each electricity user based on the power outage cost data and the power outage compensation data.

[0060] In this step, the outage cost data c(θ i , x i ) and power failure compensation data p i x i , generate the benefit function of electricity users: f(x i )=p0x i +p i x i -c(θ i , x i ). Other data can also be introduced to optimize the benefit function, such as the introduction of power grid shared cost data.

[0061] Step S104, using a preset optimal response solution algorithm, iterate the total interruption load and the benefit function of each of the electricity users until the interruptible power of each of the electricity users meets the optimal benefit value of the corresponding benefit function, and the sum of the interruptible power of all the electricity users is equal to the total interruption load, stop the iteration, and obtain the interruptible power of each of the electricity users. The interruptible power is used by the power grid system to allocate the interruption power to the electricity users and to perform power-off operations on the electricity users.

[0062] In this embodiment, the optimal benefit value is the benefit value when the benefit function of all users satisfies Nash equilibrium. Optionally, an iterative calculation is performed on the interruptible power of each user, and the determined interruptible power is fed back to the iterative process of other users. When the benefit function of all users satisfies Nash equilibrium and the sum of the interruptible power of all users equals the total interruptible load, the optimal solution is obtained.

[0063] In one embodiment, determining the power outage cost data and the power outage compensation data for each power user according to the user type includes:

[0064] Determining, according to the user type, a user type parameter, a power outage cost coefficient, and a power outage compensation price for each of the electricity users;

[0065] Determining the power outage cost data for each of the electricity users based on the user type parameter and the power outage cost coefficient;

[0066] The power outage compensation data of each of the electricity users is determined according to the power outage compensation electricity price.

[0067] In this embodiment, a user type parameter can be preset based on the user type, where a smaller user type parameter indicates a lower willingness of the user to interrupt power. The power outage compensation price is an incentive for implementing interruptible load management. To reduce the economic losses caused by power outages, a reasonable power outage compensation price can encourage users to interrupt load management. This can select users with lower power outage costs to bear more interruptible loads, thereby ensuring optimal resource allocation.

[0068] Optionally, determining the power outage cost data for each electricity user based on the user type parameter and the power outage cost coefficient includes:

[0069] The power outage cost data of each power user is determined using a preset power outage cost formula according to the user type parameter and the power outage cost coefficient, wherein the power outage cost formula is:

[0070] c(θ i , x i )=K1x i 2+K2x i -K2θ i x i ;

[0071] where c(θ i , x i ) represents the power outage cost data of the i-th electricity user, θ i represents the user type parameter of the i-th electricity user (hereinafter referred to as user i), x i represents the interruptible power quantity to be determined for the i-th electricity user, K1 and K2 both represent the power outage cost coefficients. i ∈(0, 1).

[0072] In one embodiment, generating a benefit function for each electricity user based on the power outage cost data and the power outage compensation data includes:

[0073] Determining electricity sharing cost data for each of the electricity users based on the total interrupted load;

[0074] A benefit function for each of the electricity users is generated based on the power outage cost data, the power outage compensation data, and the power sharing price data.

[0075] In this embodiment, considering the limitation of the unit ramp rate, the power shortage of the system during the peak period is calculated, and the predicted total interruption load is recorded as L. Taking into account the user's interruptible power, the new total interruption load is recorded as:

[0076] In order to further improve the response level and guide users to make reasonable decisions, the grid sharing cost parameter β is introduced. Its practical significance is that due to the existence of the new total interruption load ΔL, the grid needs to use backup power and the operating cost increases, which requires users to share the grid operation cost. The corresponding power sharing cost data of user i is recorded as β(ΔL) 2 .

[0077] Optionally, the benefit function is:

[0078] f(x i )=p0x i +p i x i -c(θ i , x i )-β(ΔL) 2 ;

[0079] β(ΔL) 2 =β(L-∑x i ) 2 ;

[0080] where f(xi ) represents the benefit function of the i-th electricity user, x i represents the interruptible power quantity to be determined for the i-th electricity user, p0 represents the electricity price, and p i x i represents the power outage compensation data of the i-th electricity user, p i The power outage compensation price of the i-th electricity user, c(θ i , x i ) represents the power outage cost data of the i-th electricity user, β(ΔL) 2 represents the power sharing cost data of the i-th power user, β represents the power sharing cost parameter, and L represents the total interruption load.

[0081] It's understandable that the size of the grid's shared cost data is related to the system's final total interruptible load, ΔL—that is, the total interruptible power reported by all users. Consequently, a non-cooperative game exists among users. When each user optimizes their own benefit function, they need to consider the impact of other users' decisions on their own. Assuming all users are rational, they will compete with each other to determine their optimal interruptible power while satisfying ΔL. When the game model reaches equilibrium, ΔL is satisfied, and each user's benefits are optimized. It's important to note that the grid's shared cost data only exists when determining a user's interruptible power. Once ΔL is satisfied, the grid's shared cost data is revoked, preventing additional costs for users not participating in interruptible load management.

[0082] Optionally, the benefit function of user i includes the decisions x of other users -i (where -i represents other users except user i), so the benefit function of the i-th electricity user when including the interruptible power decision value of other electricity users can be recorded as f i (x i , x -i The optimal response solving algorithm is used to solve the non-cooperative game model. That is, the user solves the optimal decision with his own benefit function as the target in each iteration. After obtaining the interruptible power decision value of other users, the parameters of the benefit function are changed and the next iteration is carried out.

[0083] To ensure the benefit function f i (x i , x -i ) converges to a reasonable unique equilibrium solution, assuming that for user i, there is a unique optimal decision Then the equivalent form of the benefit function is:

[0084]

[0085] Right now:

[0086]

[0087] Where α is an undetermined parameter and m represents the number of iterations of user i.

[0088] In one embodiment, the method of using a preset optimal response solution algorithm to iterate the total interruption load and the benefit function of each electricity user until the interruptible power of each electricity user satisfies the optimal benefit value of the corresponding benefit function and the sum of the interruptible power of all electricity users is equal to the total interruption load is stopped, and the interruptible power of each electricity user is obtained, includes:

[0089] Using the optimal response solution algorithm, initialize the interruptible power decision value of the i-th electricity user and the total number n of said electricity users;

[0090] For the i-th electricity user when the interruptible power decision values ​​of other electricity users are included, according to the interruptible power decision value And the benefit function f(x i ), iteratively calculate the interruptible power of the i-th electricity user

[0091] make m=m+1, judge Is it not greater than the preset threshold ε? i ;

[0092] like Then stop the iterative calculation of the interruptible power consumption of the i-th electricity user;

[0093] Continue to iteratively calculate the interruptible power of the i+1th electricity user Until n electricity users are satisfied And the total interruption load The interruptible power amount of each electricity user is obtained.

[0094] In this embodiment, since the data conditions of each user are different, the selected ε i For example, assuming that the interruptible power of each user is greater than zero, the maximum interruption amount set by user i is The power decision value can be interrupted The feasible domain is Assume that n users participate in the interruptible load management decision-making, and use the optimal response solving algorithm to solve the unique Nash equilibrium point of the non-cooperative game model:

[0095] For user i, initialize And the number of iterations, that is, the number of iterations m = 0, select the initial point in the feasible region and x (0) ; Calculate the interruptible power consumption of user i make m=m+1; when When , the iteration of user i’s interruptible power is completed, and the interruptible power of user i is fed back to other users for the iteration of interruptible power until all users And the total interruption load The interruptible power amount of each electricity user is obtained.

[0096] Optionally, the interruptible power The calculation formula is:

[0097]

[0098] in, Indicates the interruptible power decision value including other electricity users The benefit function of the i-th electricity user at time , α is an undetermined parameter.

[0099] Exemplarily, the existence and uniqueness of the Nash equilibrium of the non-cooperative game model of this embodiment.

[0100] a) Existence:

[0101] g(x i ) for x i The first-order derivative of is:

[0102]

[0103] g(x i ) for x i The second derivative of is:

[0104]

[0105] If 2K1+2β+α>0, then α>-2K1-2β holds, which means that there is a Nash equilibrium point in the non-cooperative game.

[0106] b) Uniqueness:

[0107] Use x i =r(x i ) is used to represent the optimal response function of user i. When the optimal response function is a standard function, the game model is unique. The standard function must satisfy positive definiteness (i.e., r(x)>0), monotonicity, and scalability.

[0108] For the standard function, it satisfies the positive definiteness, that is, for any α>1, αr(x)>r(αx), so:

[0109]

[0110] After other parameters are selected, a sufficiently large α is selected to ensure that r(x i )>0, which ensures that the standard function satisfies the positive definiteness.

[0111] For the standard function to satisfy monotonicity, let x≥x′, it is easy to get r(x)-r(x′)>0, that is, the function is monotonically increasing, and the standard function satisfies monotonicity.

[0112] For standard functions, scalability is achieved:

[0113]

[0114] In the case of α>1, when r(x i ) satisfies the positive definiteness, it can be guaranteed that αr(x)-r(αx)>0, that is, the standard function satisfies the scalability.

[0115] When other parameters are determined, by selecting a sufficiently large parameter α, the optimal response function r(x) can satisfy positivity, monotonicity and scalability, becoming a standard function, so that the non-cooperative game model has a unique Nash equilibrium point.

[0116] As an example and not a limitation, the following provides a power distribution scenario implemented based on the power interruption load distribution method of the present application.

[0117] Assume that the power company calculates and predicts that the total interrupted load during a peak period will be 12.9MW, meaning that 12.9MW of load will need to be cut for one hour. Under the influence of factors such as high electricity prices and grid costs, there are six industrial users willing to participate in the power company's interruptible load management. The electricity price for this period is known to be p0 = 300 yuan / (MW·h), the grid cost parameter is β = 100, and the power company determines the user's power outage cost coefficient based on historical data as K1 = 2.5 and K2 = 250. Let α = 800. The interruption electricity prices, actual type parameters, and maximum interruptible loads of these six users are listed in the following table:

[0118]

[0119] After obtaining the interrupted power of other users, each user determines the optimal interruption amount based on the principle of maximizing its own benefits. In this way, multiple rounds of iterations are performed according to the above step S104, and the power company can obtain the final interrupted power of each user. Each user can also report his or her own benefit function to the power grid company, which will then conduct comprehensive iterations.

[0120] When a user's data reaches the convergence condition, the benefit is considered to have reached maximum, and the iteration is terminated. The value fed back to other users is the final converged value, and other users continue to iterate until the benefits of all users have converged. When the ε selected by six users is 0.3%, 1%, 0.7%, 1%, 0.7%, and 0.8%, the final interrupted power consumption and benefit information are shown in the following table:

[0121]

[0122]

[0123] As can be seen from the table above, the actual interrupted electricity consumption of the six users is within their respective feasible regions, and the sum of their interrupted electricity consumption meets the total interrupted load. Furthermore, all users have achieved positive benefits and are motivated to participate in interruptible load management. Further analysis of the capacity allocation among the six users from the power company's perspective reveals that, since User 1's interruption compensation price is higher, and the interruption capacity of the remaining five users is sufficient to meet the total interrupted load, the power company can select the best option and sign interruptible load contracts with Users 2, 3, 4, 5, and 6.

[0124] From the results of the case analysis, it can be seen that when the non-cooperative game model reaches equilibrium, users who meet the total interruption load and have lower power outage costs and interruption compensation prices bear more interruption capacity, achieving better results both from the perspective of the power company and social benefits.

[0125] In order to implement the power interruption load distribution method corresponding to the above method embodiment, to achieve the corresponding functions and technical effects.
