Description

Technical Field

[0001] This invention relates to the field of electricity cost management, and specifically to an intensive electricity cost calculation system and method for industrial parks where multiple enterprises share a transformer. Background Technology

[0002] Many industrial parks today refer to business communities established in a fixed geographical area, comprised of numerous manufacturing and service companies of the same industry. These parks aim to achieve greater environmental, economic, and social benefits through joint management of environmental and economic matters. These industrial parks are formed by the clustering of multiple companies of the same industry within the same area, creating a business cluster.

[0003] For a long time, most of the power supply and distribution facilities in these industrial parks have been invested in, constructed, and operated by the park owners themselves. Park owners and property management companies have added equipment maintenance, wear and tear, and even other unrelated costs to the electricity price, thus siphoning off the benefits of the national electricity price reduction policy, increasing the electricity costs for end-user enterprises in the parks, and damaging the business environment. The transformation of industrial parks involves multiple areas such as property rights, electricity, and pricing; a change in one area has far-reaching consequences, and there is no precedent nationwide. To thoroughly solve this problem, some localities have introduced a solution for the first time: "the government funds the transformation of the power distribution system, the power supply department undertakes the transformation and construction tasks, and ultimately achieves direct power supply and meter reading to end users." This represents a shift from the previous "one meter per park package sale" to "connecting the last mile of power supply to the park's end users through meter reading and settlement." The new electricity cost calculation, allocation, verification, and settlement model introduced specifically for industrial park transformation is the core solution to the problem of meter reading to end users in industrial parks.

[0004] The challenges and pain points in designing the new electricity billing model lie in the following: An industrial park often has a dozen or more businesses and individuals sharing one or more transformers, and there may be diverse electricity prices for residential, industrial, and commercial users. Currently, Guangdong's electricity pricing requirements stipulate that a basic electricity fee is charged for a transformer used by a single business based on capacity, demand, and the number of days it is used. However, no basic electricity fee is charged to users subject to residential or some industrial and commercial electricity prices. For industrial parks, how can the "basic electricity fee" for a transformer shared by a dozen or more businesses and individuals be calculated and collected fairly and reasonably? If a user uses electricity every other month or intermittently, how can the electricity consumption fee and the basic electricity fee be calculated and verified fairly? What happens when a user's electricity price changes, leading to new additions or cancellations? Therefore, achieving fair and reasonable calculation and allocation of electricity bills within industrial parks has become an urgent technical challenge. Summary of the Invention

[0005] The technical problem to be solved by this invention is to provide an intensive electricity cost calculation method and system for industrial parks, which realizes fair and reasonable calculation and allocation of electricity costs within industrial parks, eliminates the phenomenon of price increases for electricity transferred by "intermediate layers", reduces the electricity costs of end-user enterprises in the park, and improves the efficiency and transparency of electricity cost management.

[0006] To solve the above-mentioned technical problems, as a first aspect of the present invention, an intensive electricity billing system for industrial parks is provided, comprising:

[0007] The data interaction module is used to extract basic data of industrial park users from the power grid marketing system database, including meter reading codes, records, electricity consumption, electricity price and electricity charge calculation information;

[0008] The user settings module is used to classify users in each industrial park, set up owner users and at least one terminal user, and add extended attributes to these users to distinguish their roles, while verifying the correctness of the user settings; the extended attributes are industrial park owners and industrial park terminal users.

[0009] The integrated calculation module is used to perform intensive calculation of electricity charges for users in the industrial park according to the set rules and algorithms. This includes adding user attribute extension tags, setting up user relationships, clarifying charging details, setting up billing profiles, and algorithms and rules for basic electricity charge allocation calculation.

[0010] The system verification and inspection module is used to verify the correctness of the calculation results, ensuring that the electricity consumption of the industrial park's owners is greater than the sum of the electricity consumption of the end users, and that the basic electricity charges of the owners' transformers are greater than the sum of the basic electricity charges of the end users.

[0011] The user settings module further includes:

[0012] The user classification unit is used to classify users in the industrial park into owners and end users, and add corresponding extended attributes to each type of user.

[0013] The relationship setting unit is used to establish the total-to-score relationship between industrial park owners and end users, and to ensure that all relevant users are located in the same meter reading segment.

[0014] The verification unit is used to verify the count of customer numbers in the industrial park to ensure that the number and relationship between owner households and end households meet the preset conditions.

[0015] The integrated computing module further includes:

[0016] The user attribute extension module is used to add extended attributes for industrial park owners and end users, and to set user categories, including: adding the "Industrial Park Owner" extended attribute for industrial park owners; adding the "Industrial Park End User" extended attribute for industrial park end users; and setting the user category of both industrial park owners and end users to dedicated transformer customers.

[0017] The user relationship settings module is used to set up the relationship between industrial park owners and end users, and to ensure consistency in metering and billing. This includes: linking the metering points of industrial park owners and end users through a total-to-point relationship; ensuring that park owners and end users are in the same metering zone, enabling simultaneous meter reading and billing; uniformly using the actual power factor of park owners as the actual power factor for all users; and ensuring that the metering method of industrial park end users is consistent with that of owners.

[0018] The detailed charging rules module clarifies the rules for allocating electricity costs and the billing standards for end users within the industrial park. This includes: dividing end-user electricity costs into three parts: basic electricity cost allocation, electricity consumption charge, and power factor adjustment charge; allocating the basic electricity cost based on the proportion of electricity consumption per meter to the total electricity consumption per meter; applying the electricity consumption charge according to the total meter price; and calculating the power factor adjustment charge based on the total meter power factor assessment standards.

[0019] The billing profile setting module is used to set up billing profiles for different types of users, including basic electricity charge calculation methods, electricity prices, and power regulation assessment standards. For regular users, the billing profile is consistent with the main metering point, and the basic electricity charge is allocated according to the proportion of electricity consumption. For users with special electricity prices (such as residents, charging piles, and 5G base stations), corresponding billing profiles and power regulation assessment standards are set according to their electricity consumption characteristics and capacity.

[0020] The basic electricity cost allocation calculation module is used to calculate the basic electricity cost to be allocated to each user based on user classification and electricity consumption; to formulate the algorithm and rules for basic electricity cost allocation calculation; and to consider the correlation between power regulation standards, electricity prices, and capacity ranges to ensure the accuracy and fairness of the allocation.

[0021] The basic electricity cost allocation calculation module employs five basic electricity cost allocation models, including:

[0022] If the owner is a high-voltage electricity supplier with high metering and industrial electricity use, and the transformer operating capacity is greater than 160kVA, then the basic electricity fee is calculated "based on transformer capacity".

[0023] For owners whose electricity supply and metering are high-voltage or other types of electricity use, and whose transformer operating capacity is greater than 160kVA, the basic electricity fee is calculated "based on transformer capacity".

[0024] For owners whose electricity supply is high-voltage and metered low-voltage, and whose transformer operating capacity is greater than or equal to 100kVA and less than or equal to 160kVA, their basic electricity fee is calculated "based on transformer capacity".

[0025] For owners whose electricity supply is high-voltage and metered low-voltage, industrial electricity use, and whose transformer operating capacity is less than 100kVA, the basic electricity fee calculation method is "not calculated".

[0026] For owners whose electricity supply is high-voltage and metered, and whose transformer operating capacity is greater than 3000kVA, the basic electricity fee is calculated "based on the actual maximum demand".

[0027] Among them, the special electricity price users include at least: residents, charging piles and 5G base stations.

[0028] Accordingly, as another aspect of the present invention, a method for intensive electricity cost calculation in industrial parks is also provided, which includes the following steps:

[0029] The data interaction step involves extracting basic data of industrial park users from the power grid marketing system database, including meter reading codes, records, electricity consumption, electricity price, and electricity bill calculation information.

[0030] The user setup process involves classifying users in each industrial park, setting up owner accounts and at least one terminal account, adding extended attributes to these users to distinguish their roles, and verifying the correctness of the user setup; the extended attributes are industrial park owners and industrial park terminal accounts.

[0031] The comprehensive calculation steps, based on the established rules and algorithms, perform intensive calculation of electricity charges for users within the industrial park. This includes adding user attribute extension tags, setting up user relationships, clarifying charging details, setting up billing profiles, and algorithms and rules for basic electricity charge allocation calculation.

[0032] The system verification and inspection steps verify the correctness of the calculation results, ensuring that the electricity consumption of the industrial park's owners is greater than the sum of the electricity consumption of the end users, and that the basic electricity charges of the owners' transformers are greater than the sum of the basic electricity charges of the end users.

[0033] The user setup steps further include:

[0034] The user classification process involves classifying users within the industrial park into owner users and end users, and adding corresponding extended attributes for each user category.

[0035] The steps for setting up relationships include establishing a general-to-subordinate relationship between industrial park property owners and end users, and ensuring that all relevant users are located in the same meter reading segment.

[0036] The verification process involves checking the count of customer IDs in the industrial park to ensure that the number and relationship between owner-occupiers and end-users meet the preset conditions.

[0037] The comprehensive calculation step further includes:

[0038] The steps for extending user attributes include adding extended attributes for industrial park owners and end users, and setting user categories, including: adding the "Industrial Park Owner" extended attribute for industrial park owners; adding the "Industrial Park End User" extended attribute for industrial park end users; and setting the user category for both industrial park owners and end users to dedicated transformer customers.

[0039] The user relationship setup steps involve establishing the relationship between industrial park owners and end users, and ensuring consistency in metering and billing. This includes: linking the industrial park owner's metering points with the end user's metering points through a general-to-specific relationship; ensuring that park owners and end users are in the same metering zone for simultaneous meter reading and billing; uniformly using the actual power factor of the park owner as the actual power factor for all users; and ensuring that the metering method for industrial park end users is consistent with that of the owner.

[0040] The detailed charging rules clarify the steps and define the rules for allocating electricity costs to end users within the industrial park, including: dividing end-user electricity costs into three parts: basic electricity cost allocation, electricity consumption charge, and power factor adjustment charge; allocating the basic electricity cost based on the proportion of electricity consumption per meter to the total electricity consumption per meter; charging the electricity consumption charge according to the total meter price; and calculating the power factor adjustment charge based on the total meter power factor assessment standard.

[0041] The billing profile setup steps involve setting up billing profiles for different types of users, including basic electricity cost calculation methods, electricity prices, and power regulation assessment standards. Specifically, for regular users, the billing profile is consistent with the main metering point, and the basic electricity cost is allocated proportionally based on electricity consumption. For users with special electricity prices (such as residents, charging piles, and 5G base stations), corresponding billing profiles and power regulation assessment standards are set up according to their electricity consumption characteristics and capacity.

[0042] The basic electricity cost allocation calculation steps include: calculating the basic electricity cost to be allocated to each user based on user classification and electricity consumption; formulating algorithms and rules for basic electricity cost allocation calculation; and considering the correlation between power regulation standards, electricity prices, and capacity ranges to ensure the accuracy and fairness of the allocation.

[0043] The basic electricity cost allocation calculation step employs five basic electricity cost allocation models, including:

[0044] If the owner is a high-voltage electricity supplier with high metering and industrial electricity use, and the transformer operating capacity is greater than 160kVA, then the basic electricity fee is calculated "based on transformer capacity".

[0045] For owners whose electricity supply and metering are high-voltage or other types of electricity use, and whose transformer operating capacity is greater than 160kVA, the basic electricity fee is calculated "based on transformer capacity".

[0046] For owners whose electricity supply is high-voltage and metered low-voltage, and whose transformer operating capacity is greater than or equal to 100kVA and less than or equal to 160kVA, their basic electricity fee is calculated "based on transformer capacity".

[0047] For owners whose electricity supply is high-voltage and metered low-voltage, industrial electricity use, and whose transformer operating capacity is less than 100kVA, the basic electricity fee calculation method is "not calculated".

[0048] For owners whose electricity supply is high-voltage and metered, and whose transformer operating capacity is greater than 3000kVA, the basic electricity fee is calculated "based on the actual maximum demand".

[0049] Among them, the special electricity price users include at least: residents, charging piles and 5G base stations.

[0050] Implementing the embodiments of the present invention has the following beneficial effects:

[0051] This invention provides a centralized electricity cost calculation method and system for industrial parks, enabling fair and reasonable calculation and allocation of electricity costs within the park, eliminating the markup imposed by intermediaries in the electricity supply chain. It reduces electricity costs for end-user businesses within the park, stimulating their willingness to expand operations and production. It improves the efficiency and transparency of electricity cost management, thereby reducing human error and risk. It also possesses good scalability, adapting to the electricity needs of different industrial parks and users. Attached Figure Description

[0055] Figure 3 This is a schematic diagram of the main process of an embodiment of the intensive electricity cost calculation method for industrial parks provided by the present invention. Detailed Implementation

[0056] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0057] To understand the technical solution of this invention, the technical terms involved in this invention will be introduced first as follows:

[0058] User ID: For the convenience of searching and management, users are assigned a number, which serves as a unique identifier for each user.

[0059] Username: The name a user leaves when registering an account, usually an individual, company, or other related name.

[0060] Electricity consumption categories: Power grid companies classify users according to the nature of their electricity consumption. Common categories include public transformer customers (users who use public transformers owned by the power supply company, which account for the majority of residential electricity consumption), public line dedicated transformer customers (users who use transformers owned by the power supply company but whose ownership belongs to the user, including large-scale industrial and commercial users), dedicated line dedicated transformer customers (users who use lines and transformers owned by the user, mainly large-scale industrial and commercial users), local power plant customers, and transformer area assessment customers.

[0061] Rated capacity of a transformer: A basic parameter of a transformer, referring to the maximum capacity that it can continuously output during its specified normal service life. It is the conventional value of apparent power at the main tap and is marked on the transformer nameplate at the time of manufacture.

[0062] Contract capacity: refers to the total capacity of user equipment permitted by the power supply department and included in the power supply contract (the specific value will be specified in the contract), which is usually less than or equal to the maximum capacity of the connected transformer.

[0063] Voltage level: This refers to the rated voltage level series of power systems and electrical equipment. It is usually divided into low voltage (220V or 380V), high voltage (10kV-220kV), and ultra-high voltage (330kV-750kV).

[0064] Metering method: refers to the metering and installation method of the electricity metering device, which is divided into high supply and high metering (the voltage of the electricity metering device setting point is the same as the supply voltage and is above 10 (6) kV), high supply and low metering (the voltage of the electricity metering device setting point is lower than the user's supply voltage), and low supply and low metering (the voltage of the electricity metering device setting point is the same as the user's supply voltage, for example, most residential electricity use is low supply and low metering).

[0065] Metering point: refers to the location where a metering device is installed. Metering points are divided into electricity customer billing points and gateway metering points.

[0066] Metering point relationships: master-slave relationship, high-volume high-demand segmented relationship, cross-household total-splitting relationship, shared self-slave relationship, master-sub-metering, etc. are combinations made for accurate billing and special on-site conditions of metering points.

[0067] Metering point uses: mainly divided into reference meters (used to measure line loss and line load but not for calculating electricity bills) and general billing meters (used to measure energy consumption as the basis for electricity bill settlement).

[0068] Electricity consumption categories at metering points: These are secondary classifications under the major categories of electricity consumption, including general industrial and commercial and other, residential, large industrial electricity, commercial, agricultural irrigation, and local power plant users.

[0069] Electricity calculation methods: divided into metered metering, proportional (settlement based on a certain percentage of total electricity consumption), and fixed-amount (settlement based on a fixed amount of electricity each time).

[0070] Fixed quantity and ratio value: The fixed electricity billing value agreed upon with the user and specified in the contract.

[0071] Electricity price: officially known as retail electricity price, refers to the price at which power grid operators sell electricity to end users. Retail electricity prices are subject to government pricing, unified policies, and tiered management. Pricing methods include two-part tariffs and single-part tariffs.

[0072] Basic electricity charge calculation method: The basic electricity charge for transformers in the two-part electricity pricing system can be calculated in three ways: based on maximum demand, based on transformer capacity, and based on actual maximum demand.

[0073] Demand rating: This refers to the maximum demand that a user can use according to the agreement. If the user's actual maximum demand exceeds the rating by 5%, the basic electricity fee for the portion exceeding 5% will be doubled.

[0074] Maximum demand: refers to the average power consumption of customers during a certain period of time (currently 15 minutes in my country) within a certain settlement period (generally one month), and the highest single indication value is retained as the maximum demand for this settlement period.

[0075] Power factor assessment methods: There are two methods: standard assessment and no assessment.

[0076] Power factor standards are divided into three types: 0.8, 0.85, and 0.9. The basis and standard for adjusting electricity charges based on power factor is the "Power Factor Adjustment Method" jointly issued by the former Ministry of Water Resources and Electric Power and the State Price Bureau in 1983.

[0077] Loss billing indicator: There are two types: yes or no.

[0078] Transformer loss: also known as transformer loss, refers to the sum of no-load loss Po, short-circuit loss Pk, and stray loss Ps. Transformers in operation also consume a certain amount of electrical energy.

[0079] Transformer operating days: This is an important parameter for calculating the basic electricity charge. Usually, the transformer operating days are 30 days for monthly billing. If it is not a whole month, the basic electricity charge for the transformer is calculated based on the number of operating days.

[0080] Basic electricity cost allocation methods include proportional allocation (no charge), allocation based on a percentage value, allocation based on capacity ratio, and allocation based on a fixed value. These are important parameters when calculating basic electricity costs.

[0081] Work order: refers to work orders in the business process, including new installation, class change, transfer of ownership, capacity increase, capacity decrease, meter replacement, suspension, resumption, non-permanent capacity reduction, non-periodic billing, and account cancellation for users (transformers).

[0082] Periodic billing and non-periodic billing: Normal periodic billing settles electricity bills on a monthly basis, while non-periodic billing settles electricity bills on a non-periodic basis.

[0083] Shared transformer: refers to a situation where multiple users share one or more transformers. Most existing users are left over from historical reasons, and current policies do not allow new shared transformer users to appear.

[0084] Power supply methods: There are usually four methods: public line dedicated transformer power supply, dedicated line dedicated transformer power supply, shared dedicated transformer power supply, and public transformer power supply.

[0085] Power factor adjustment fee: Also known as the power factor adjustment fee, this is a charge levied by the power company based on the average power factor calculated by the customer over a period of time, taking into account their active and reactive power consumption. A higher power factor indicates higher equipment utilization efficiency and may result in a discount on electricity rates; conversely, a lower power factor may require additional payment. Power factors are categorized into three levels: 0.8, 0.85, and 0.9, depending on the user's electricity usage, electricity price, and transformer capacity.

[0086] like Figure 1 The diagram shown illustrates a structural schematic of an embodiment of an integrated electricity cost calculation system for industrial parks provided by the present invention; in conjunction with... Figure 2 As shown, in this embodiment, the industrial park centralized electricity billing system 1 includes:

[0087] The data interaction module 10 is used to extract basic data of industrial park users from the power grid marketing system database, including meter reading codes, records, electricity consumption, electricity price, and electricity charge calculation information. It can be understood that the data interaction module 10 extracts all basic data related to meter reading codes, records, electricity consumption, electricity price, and electricity charge calculation for its region from the integrated power grid marketing system database. The marketing system can be regarded as a database containing power grid purchase and sale information for all regions. This system has a direct interface with the marketing system, so it can obtain all the required basic data information of industrial park users from the database.

[0088] User settings module 11 is used to classify users in each industrial park, set up owner users and at least one terminal user, and add extended attributes to these users to distinguish their roles, while verifying the correctness of the user settings; the extended attributes are industrial park owners and industrial park terminal users.

[0089] The comprehensive calculation module 12 is used to perform intensive calculation of electricity charges for users in the industrial park according to the set rules and algorithms. This includes adding user attribute extension tags, setting user relationships, clarifying charging details, setting billing files, and algorithms and rules for basic electricity charge apportionment calculation.

[0090] The system verification and inspection module 13 is used to verify the correctness of the calculation results, ensuring that the electricity consumption of the industrial park owners is greater than the sum of the electricity consumption of the end users, and that the basic electricity fee of the owners' transformers is greater than the sum of the basic electricity fees of the end users.

[0091] More specifically, the user settings module 11 further includes:

[0092] The user classification unit is used to categorize users within the industrial park into property owners and end users, and adds corresponding extended attributes to each user category. Specifically, the user classification unit categorizes users in each industrial park, setting up property owners and multiple end users. Each industrial park must have at least one property owner, and the remaining users are end users. All users within each industrial park are assigned the same customer ID for identification. Property owners and end users in the industrial park need to have the extended attributes "Industrial Park Property Owner" and "Industrial Park End User," respectively. Both property owners and end users are classified as dedicated transformer customers. By analogy, property owners in the industrial park can be compared to landlords, and end users can be compared to tenants.

[0093] The relationship setting unit is used to establish the total-to-score relationship between industrial park owners and end users, and to ensure that all relevant users are located in the same meter reading segment.

[0094] The verification unit is used to verify the count of customer IDs in the industrial park, ensuring that the number and relationship between property owners and end users meet preset conditions. In one example, assuming the count of customer IDs in the industrial park is X, the number of property owners is Y1, and the number of end users is Y2, the following conditions must be met simultaneously: X = Y1 + Y2, and both Y1 and Y2 are greater than or equal to 1. Otherwise, it indicates a corresponding error, requiring staff to check and promptly correct the industrial park user files.

[0095] In a specific example, the integrated computing module 12 further includes:

[0096] The user attribute extension module is used to add extended attributes for industrial park owners and end users, and to set user categories, including: adding the "Industrial Park Owner" extended attribute for industrial park owners; adding the "Industrial Park End User" extended attribute for industrial park end users; and setting the user category of both industrial park owners and end users to dedicated transformer customers.

[0097] The user relationship settings module is used to set up the relationship between industrial park owners and end users, and to ensure consistency in metering and billing. This includes: linking the metering points of industrial park owners and end users through a total-to-point relationship; ensuring that park owners and end users are in the same metering zone, enabling simultaneous meter reading and billing; uniformly using the actual power factor of park owners as the actual power factor for all users; and ensuring that the metering method of industrial park end users is consistent with that of owners.

[0098] Specifically, in the user relationship settings module, the relationship between industrial park owners and end users is configured. First, because there is an electricity deduction relationship between owners and end users, the metering points of industrial park owners and end users need to be linked through a master-slave relationship. Note that the file should be set to "Master-Slave Relationship" rather than "Master-Slave Relationship (Master Meter)". Second, park owners and end users establishing a master-slave relationship must be maintained in the same meter reading section, strictly adhering to simultaneous meter reading and billing. Third, the industrial park uniformly uses the actual power factor of the park owner (i.e., the master meter) as the actual power factor for all users establishing a master-slave relationship. Industrial end users do not need to record the total positive reactive power and maximum demand, and the file does not need to maintain the meter reading type for the total positive reactive power and maximum demand. Fourth, the metering method of the metering points of industrial park end users must be consistent with that of the owner's metering points.

[0099] The detailed charging rules module clarifies the rules for allocating electricity costs and the billing standards for end users within the industrial park. This includes: dividing end-user electricity costs into three parts: basic electricity cost allocation, electricity consumption charge, and power factor adjustment charge; allocating the basic electricity cost based on the proportion of electricity consumption per meter to the total electricity consumption per meter; applying the electricity consumption charge according to the total meter price (time-of-use pricing based on the application electricity category and voltage level); and calculating the power factor adjustment charge based on the total meter power factor assessment standards.

[0100] The billing profile setting module is used to set up billing profiles for different types of users, including basic electricity charge calculation methods, electricity prices, and power regulation assessment standards. Specifically, for regular users, the billing profile is consistent with the main metering point, and the basic electricity charge allocation method is based on electricity consumption. Specifically, the basic electricity charge calculation method must be consistent with the main metering point, the electricity price must be consistent with the main metering, the power regulation assessment standard must be consistent with the main metering, and the basic electricity charge allocation method must be set to "allocated based on electricity consumption," with the basic electricity charge allocation value empty. For users with special electricity prices (such as residents, charging piles, and 5G base stations), corresponding billing profiles and power regulation assessment standards are set according to their electricity consumption characteristics and capacity.

[0101] For users with special electricity rates:

[0102] 1. Residents (corresponding to end-user B): Residents with combined meter electricity prices are not subject to force adjustment assessment, but participate in the basic electricity fee sharing, and are not charged after sharing; for school combined meter electricity price (institutional combined meter electricity price) users, if their electricity capacity is less than 100 kVA, they are not subject to force adjustment assessment (see file setting example B1 for details). If their electricity capacity is greater than or equal to 100 kVA, the force adjustment assessment standard for school combined meter electricity price (institutional combined meter electricity price) end-users is 0.85 (see file setting example B2 for details).

[0103] 2. Charging piles (corresponding to terminal user C): Charging piles need to participate in the basic electricity fee sharing, but are not included in the basic electricity fee. The electricity price must be selected according to the corresponding main metering electricity price with "charging". The power adjustment standard needs to be formulated after summarizing the industrial capacity of the park users (see C, C1, and C2 in File Setting Case 2 for details).

[0104] 3. 5G Base Stations (corresponding to Terminal User D): If the power consumption of a 5G base station is less than 100 kVA (kW), it will not be subject to power regulation assessment, will not participate in basic electricity fee sharing, and will not be charged a basic electricity fee. If the power consumption of a 5G base station is greater than or equal to 100 kVA (kW), it needs to share the basic electricity fee of the park's main meter and be subject to power regulation assessment according to the proportion of electricity consumption (for power consumption greater than or equal to 100 kVA, see settings D1 and D2 in scenario 1 for the implementation method). The basic electricity fee sharing calculation module is used to calculate the basic electricity fee to be shared by each user based on user classification and electricity consumption; to formulate the algorithm and rules for basic electricity fee sharing calculation; and to consider the correlation between power regulation standards and electricity prices and capacity ranges to ensure the accuracy and fairness of the sharing.

[0105] The basic electricity cost allocation calculation module is used to calculate the basic electricity cost to be allocated to each user based on user classification and electricity consumption; to formulate the algorithm and rules for basic electricity cost allocation calculation; and to consider the correlation between power regulation standards, electricity prices, and capacity ranges to ensure the accuracy and fairness of the allocation.

[0106] The data verification module is used to verify the above data. Specifically, the data must meet the following requirements: the electricity consumption of industrial park owners is greater than the sum of the electricity consumption of end users; and the basic electricity charges of transformers for industrial park owners are greater than the sum of the basic electricity charges for end users.

[0107] Specifically, in the basic electricity cost allocation calculation module, the power adjustment standard value is related to the electricity price and capacity range; specifically, the average power factor is calculated based on the active and reactive power used by the customer within a certain period (such as one month or one year), and the relevant electricity cost is charged accordingly.

[0108] The basic electricity charge is calculated based on the customer's transformer capacity or maximum demand and the basic electricity price approved by the state.

[0109] The basic electricity cost allocation calculation module employs five basic electricity cost allocation models, including:

[0110] For the first category, if the owner is a high-voltage electricity supplier with high metering and industrial electricity use, and the transformer operating capacity is greater than 160kVA, then the basic electricity fee is calculated "based on transformer capacity".

[0111] Base station users with a capacity of 100 kVA or less are not included in the basic electricity fee sharing within the park, and their basic electricity fee is set to "not calculated". The setting of the basic electricity fee sharing method as "shared proportionally by electricity consumption" is only for standardizing park records; in reality, the basic electricity fee is not shared proportionally by electricity consumption, and there will be no under-collection of the total basic electricity fee for the park.
