Description

Method and system for connection between market-oriented attribute change and electricity bill settlement of industrial and commercial users

technical field

The invention belongs to the technical field of electric power marketing, and in particular relates to a method and a system for connecting industrial and commercial users' marketization attribute change and electricity bill settlement.

Background technique

With the publication of relevant documents on further deepening the market-oriented reform of coal-fired power generation on-grid electricity prices, industrial and commercial users are encouraged to enter the electricity market on a quarterly basis. For industrial and commercial users who have not yet entered the market, power grid companies will purchase electricity on behalf of them. For the three types of agency power purchase users who are high energy-consuming, have coal-fired self-provided power plants, or have entered the market but have withdrawn without legitimate reasons, the price of general agency power purchase users is 1.5 times the agency purchase price.

After this reform, the dimensions of the market-oriented attributes of power users have increased, and at the same time, the information of some dimensions needs to be identified and provided by the power trading center. In the existing technology, the data is exchanged and checked several times mainly through the offline list. In the face of tens of millions of power users, the efficiency of power grid enterprises to maintain the market-oriented attributes of power users is greatly reduced. An application method for electricity rate risk prevention and control based on electric power customer labels (CN106845747B), establishes a basic label for each user, and then determines the electricity rate risk prevention and control process corresponding to the customer by identifying the basic label.

On the other hand, the purpose of changing the market-oriented attributes of power users is to provide a basis for the execution of electricity prices for electricity bill settlement. In the application method of electricity bill risk prevention and control based on power customer labels (CN106845747B), in order to realize the customer corresponding electricity bill risk prevention and control process and the basic label It is also necessary to generate complex tags, and then identify the complex tags to update the electricity cost risk prevention and control process, that is, the change of market-oriented attributes of current power users and the settlement of electricity bills cannot be carried out at the same time in time, otherwise the market-oriented attributes of power users Changes will cause electricity users to implement wrong electricity prices when they settle electricity bills. All in all, there is a lack of a smooth connection method between the market-oriented attribute change of power users and the settlement of electricity bills.

Contents of the invention

In order to solve the deficiencies in the prior art, the present invention provides a method and system for connecting industrial and commercial users’ marketization attribute change and electricity bill settlement, creating a marketization state that uniquely corresponds to the electricity consumption information of industrial and commercial users within a certain period of time Representation, there is a time-synchronous relationship between the marketization state representation and the electricity fee.

The present invention adopts the following technical solutions.

On the one hand, the present invention proposes a method for connecting industrial and commercial users' market-oriented attribute change and electricity bill settlement, including:

Step 1. Based on the interaction mechanism, generate a unique marketization state representation for industrial and commercial users; the determinants of the marketization state representation include: a marketization attribute label, and three marketization attribute discrimination fields; among them, the marketization attribute label includes: the label takes effect Time stamp, label invalidation time stamp; market-oriented attribute discrimination fields include: field effective time stamp, field invalidation time stamp;

Step 2. When settling the electricity bills generated by industrial and commercial users in the historical time period [t _m , t _n ] at time point T, use the sliding time window to monitor the time t _i when the marketization state representation of industrial and commercial users changes one by one, i= 1,2...N; among them, t _m <t _i <t _n <T, N is the total number of time;

Use the time t _i to divide the historical time period [t _m ,t _n ] into multiple sub-time periods, and use the effective marketization attribute labels and effective marketization attribute discrimination fields in each sub-time period to determine the corresponding sub-time period The marketization state representation of industrial and commercial users in China;

Step 3, within each sub-period, determine the user's electricity price according to the marketization state representation of industrial and commercial users;

Step 4: Settle the electricity charges of the industrial and commercial users in the historical time period [t _m , t _n ] by using the user electricity prices in each sub-time period.

Market-oriented attribute labels also include: registered non-trading users, market-oriented direct purchase users, market-oriented retail users, and power purchase agent users;

The market-oriented attribute discrimination field also includes: whether it is delisted without justified reasons, whether it is a high energy-consuming enterprise, and whether it has a coal-fired self-owned power plant.

In different time periods, the marketization state representation of each industrial and commercial user consists of one effective marketization attribute label and three effective marketization attribute discrimination fields, and the marketization attribute label and marketization attribute discrimination fields are independent of each other.

Step 1 includes:

Step 1.1, when industrial and commercial users register, the power trading center pushes the user registration information to the grid enterprise, and the time when the power trading center pushes the user registration information to the grid enterprise is the first time when the label becomes effective, and the first time when the label becomes effective corresponds to the market for industrial and commercial users The moment when the personalized attribute label is changed from "agent electricity purchase user" to "registered non-trading user";

Step 1.2, when industrial and commercial users handle the market entry, the power trading center pushes the user's market entry request to the power grid enterprise through the verification interface, and the power grid enterprise returns to the power trading center whether the user meets the market entry conditions;

If so, the power trading center pushes the user's market entry information to the power grid enterprise, and the time when the power trading center pushes the user's market entry information to the grid enterprise is the second time when the label becomes effective, and the second time when the label becomes effective corresponds to the marketization attribute label of industrial and commercial users. The moment when the "registered non-trading user" is changed to "market direct purchase user" or "market retail user" is also the first time when the label becomes invalid;

If not, the power trading center will not push the user's market entry information to the power grid enterprise, the market-oriented attribute label of the industrial and commercial user will not change, and the label will remain unchanged as soon as it becomes effective;

Step 1.3, after the marketization attribute label takes effect, use the weight classification method based on the TF-IDF algorithm to divide the weight of the marketization attribute discrimination field; use the weight obtained by division and the weighted sum of the marketization attribute discrimination field as " The electricity consumption information of “market direct purchase users” or “market retail users”; among them, when weight classification is performed based on the TF-IDF algorithm, the moment when the weight of any market-oriented attribute discrimination field is not 0 is used as the time of the market-oriented attribute discrimination field Field effective time stamp, the moment when all the market-oriented attribute discrimination fields have corresponding weights of 0 is used as the field failure time scale of the market-oriented attribute discrimination field;

Step 1.4, when the "market direct purchase user" or "market retail user" handles the change of electricity consumption information, the power grid enterprise provides a power consumption information change request to the power trading center, and repeats step 1.3 to update the weight to obtain the "market direct purchase user " or "market retail users" electricity consumption information update content, the power trading center will feed back the market-oriented attribute discrimination field to the power grid enterprise according to the electricity consumption information update content;

Step 1.5, when the "market direct purchase user" or "market retail user" handles delisting, the power trading center pushes the user's delisting request to the power grid enterprise, and the "whether delisting without justifiable reason" in the market attribute judgment field is "No ", and "whether delisting without justifiable reasons" is "No"; the market-oriented attribute labels of industrial and commercial users pushed by power grid enterprises to the power trading center are changed from "market-oriented direct purchase users" or "market-oriented retail users "" is changed to "agent electricity purchase user" is the third time when the label becomes effective, and at the same time, the "whether delisted without justified reasons" in the market attribute judgment field is changed from "no" to "yes", and the third time when the label becomes effective The timestamp when the update field takes effect.

In step 1.3, in the weight classification method based on the TF-IDF algorithm, M(P, W) is used to represent the number of times a marketing attribute discrimination field W is used to mark user P, and TF(P, W) is used to represent a The proportion of the times of marketization attribute discrimination field W in all marketization attribute discrimination fields of user P, using IDF(P, T) to represent the scarcity degree of any marketization attribute discrimination field W in all marketization attribute discrimination fields, That is, the occurrence probability of the marketization attribute discrimination field W; the weight value of any marketization attribute discrimination field W of the user is obtained according to TF(P, W)×IDF(P, T).

Specifically, step 2 includes:

Step 2.1, for the historical time period [t _m ,t _n ] of industrial and commercial users, use the sliding time window to monitor the time t _i when the marketization state representation of industrial and commercial users changes one by one, i=1,2...N;

Step 2.2, use the time t _i to divide the historical time period [t _m ,t _n ] into multiple sub-time periods [t _m ,t ₁ ], [t ₁ ,t ₂ ], ..., [t _i ,t _{i+ 1} ],..., [t _N ,t _n ];

Step 2.3, use one effective marketization attribute label and three effective marketization attribute discrimination fields in each sub-time period to determine the marketization state representation of industrial and commercial users in the corresponding sub-time period; wherein, each sub-time period The marketization state of the industrial and commercial users within is unique.

In step 2.1,

In any sliding time window, if the marketization attribute label or any marketization attribute discrimination field changes, it is determined that the commercial user's marketing state representation in the sliding time window changes;

In any sliding time window, although the marketization attribute label and any marketization attribute discrimination field are changed, but the marketization attribute label is invalid or any marketization attribute discrimination field is invalid, then the market of commercial users in the sliding time window is determined Changes in the representation of the chemical state;

Among them, the effective time scale and label failure time scale of the market-oriented attribute label are compared with the sliding time window to determine whether the market-oriented attribute label is invalid in the sliding time window, and the field effective time scale and The field failure time scale is compared with the sliding time window to determine whether any marketing attribute discriminant field is invalid within the sliding time window.

In step 3, in any sub-period, when the marketization attribute label of the industrial and commercial user takes effect and is "agent electricity purchase user" or "registered non-trading user", the corresponding value of the marketization attribute label is 10, when the industrial and commercial user When the user's marketization attribute label takes effect and is a "marketization direct purchase user" or "marketization retail user", the corresponding value of the marketization attribute label is 00; when the marketization attribute label of the industrial and commercial user fails, the marketization attribute The value corresponding to the label is 00.

In step 3, in any sub-time period, when the three marketization attribute discrimination fields of industrial and commercial users are all in effect and at least one of the marketization attribute discrimination fields is "Yes", the corresponding value of the marketization attribute discrimination field is 01, when When the three marketization attribute discrimination fields of industrial and commercial users are all valid but at least one marketization attribute discrimination field is "No", the corresponding value of the marketization attribute discrimination field is 00; when any marketization attribute discrimination field of industrial and commercial users is invalid, Then the value corresponding to the marketization attribute discrimination field is 00.

The value corresponding to the marketization state representation of industrial and commercial users is the sum of the value corresponding to the effective marketization attribute label and the value corresponding to the effective marketization attribute discrimination field.

When the corresponding value of the marketization state representation of industrial and commercial users is 11, the user’s electricity price is 1.5 times the agency purchase price; when the corresponding value of the marketization state representation of industrial and commercial users is 10, the user’s electricity price is the agency purchase price; When the corresponding value of the marketization state representation is 01 or 00, the user's electricity price is the user's contract price.

The electricity fee F _[tm,tn] of industrial and commercial users in the historical time period [t _m ,t _n ] satisfies the following relationship:

分别表示子时间段[t_m,t₁]的用户电价、子时间段[t₁,t₂]的用户电价、子时间段[t_i,t_i+1]的用户电价、子时间段[t_N,t_n]的用户电价。In the formula,

Respectively represent the user electricity price of the sub-time period [t _m ,t ₁ ], the user electricity price of the sub-time period [t ₁ ,t ₂ ], the user electricity price of the sub-time period [t _i ,t _i+1 ], and the sub-time period [ t _N , t _n ] user electricity price.

On the other hand, the present invention also proposes a system for linking the change of market-oriented attributes of industrial and commercial users and the settlement of electricity bills, including: a market-oriented state representation module, a user electricity price module, and an electricity bill settlement module;

The marketization state characterization module is used to generate a unique marketization state representation for industrial and commercial users; the determinants of the marketization state representation include: a marketization attribute label, three marketization attribute discrimination fields; When the electricity bill generated in the historical time period [t _m ,t _n ] is settled, the sliding time window is used to monitor the time t _i when the marketization state representation of industrial and commercial users changes one by one, i=1,2...N; where, t _m < t _i <t _n <T, N is the total number of times; use the time t _i to divide the historical time period [t _m ,t _n ] into multiple sub-time periods, and use the effective market-oriented attribute labels and effective marketization attribute discrimination field to determine the marketization status representation of industrial and commercial users in the corresponding sub-time period;

The user electricity price module is used to determine the user electricity price according to the marketization state representation of industrial and commercial users within each sub-period;

The electricity fee settlement module is used to settle the electricity fee of industrial and commercial users in the historical time period [t _m , t _n ] by using the user electricity price in each sub-time period.

The beneficial effect of the present invention is that, compared with the prior art, it can support power grid enterprises to accurately and clearly store the market-oriented attributes of power users, efficiently and smoothly carry out information data interaction with power trading centers on market-oriented attributes of power users, and effectively transfer power The user's market-oriented attribute change is connected with the electricity bill settlement work.

In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described in this application are only some embodiments of the present invention, not all embodiments. Based on the spirit of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

On the one hand, the present invention proposes a method for connecting industrial and commercial users' market-oriented attribute change and electricity bill settlement, as shown in Figure 1, including:

Step 1. Based on the interaction mechanism, generate a unique marketization state representation for industrial and commercial users; the determinants of the marketization state representation include: a marketization attribute label, and three marketization attribute discrimination fields;

Among them, the market-oriented attribute tags include: registered non-trading users, market-oriented direct purchase users, market-oriented retail users, agency power purchase users, tag effective time stamp, and tag invalidation time stamp;

The market-oriented attribute discrimination fields include: whether it is delisted without justified reasons, whether it is a high-energy-consuming enterprise, whether it has a coal-fired self-owned power plant, the field effective time mark, and the field failure time mark;

In different time periods, the marketization state representation of each industrial and commercial user consists of one effective marketization attribute label and three effective marketization attribute discrimination fields, and the marketization attribute label and marketization attribute discrimination fields are independent of each other.

The invention generates a unique market-oriented state representation for industrial and commercial users based on an interactive mechanism.

Step 1, as shown in Figure 2, includes:

Step 1.1, when industrial and commercial users register, the power trading center pushes the user registration information to the grid enterprise, and the time when the power trading center pushes the user registration information to the grid enterprise is the first time when the label becomes effective, and the first time when the label becomes effective corresponds to the market for industrial and commercial users The moment when the personalized attribute label is changed from "agent electricity purchase user" to "registered non-trading user";

Step 1.2, when industrial and commercial users handle the market entry, the power trading center pushes the user's market entry request to the power grid enterprise through the verification interface, and the power grid enterprise returns to the power trading center whether the user meets the market entry conditions;

If so, the power trading center pushes the user's market entry information to the power grid enterprise, and the time when the power trading center pushes the user's market entry information to the grid enterprise is the second time when the label becomes effective, and the second time when the label becomes effective corresponds to the marketization attribute label of industrial and commercial users. The moment when the "registered non-trading user" is changed to "market direct purchase user" or "market retail user" is also the first time when the label becomes invalid;

If not, the power trading center will not push the user's market entry information to the power grid enterprise, the market-oriented attribute label of the industrial and commercial user will not change, and the label will remain unchanged as soon as it becomes effective;

Step 1.3, after the marketization attribute label takes effect, use the weight classification method based on the TF-IDF algorithm to divide the weight of the marketization attribute discrimination field; use the weight obtained by division and the weighted sum of the marketization attribute discrimination field as " Electricity consumption information of market direct purchase users” or “market retail users”; among them, when weight classification is performed based on the TF-IDF (Term Frequency–Inverse Document Frequency) algorithm, any market-oriented attribute discrimination field corresponds to a weight that is not 0 The moment is used as the effective time mark of the market-oriented attribute judgment field, and the time when all the market-oriented attribute judgment fields have corresponding weights of 0 is used as the field failure time mark of the market-oriented attribute judgment field;

In the weight classification method based on the TF-IDF algorithm, M(P, W) is used to represent the number of times a marketization attribute discrimination field W is used to mark user P, and TF(P, W) is used to represent a marketization attribute discrimination field The proportion of field W times in all marketable attribute discrimination fields of user P, using IDF(P, T) to represent the scarcity of any marketization attribute discrimination field W in all marketization attribute discrimination fields, that is, marketization attribute The occurrence probability of discriminant field W. If the marketization attribute discrimination field W has a small chance of appearing and is used to mark a certain user at the same time, this will make the relationship between the user and the marketization attribute discrimination field W closer. According to TF(P, W)×IDF(P, T), the weight value of any marketing attribute discrimination field W of the user is obtained.

Step 1.4, when the "market direct purchase user" or "market retail user" handles the change of electricity consumption information, the power grid enterprise provides a power consumption information change request to the power trading center, and repeats step 1.3 to update the weight to obtain the "market direct purchase user " or "market retail users" electricity consumption information update content, the power trading center will feed back the market-oriented attribute discrimination field to the power grid enterprise according to the electricity consumption information update content;

Step 1.5, when the "market direct purchase user" or "market retail user" handles delisting, the power trading center pushes the user's delisting request to the power grid enterprise, and the "whether delisting without justifiable reason" in the market attribute judgment field is "No ", and "whether delisting without justifiable reasons" is "No"; the market-oriented attribute labels of industrial and commercial users pushed by power grid enterprises to the power trading center are changed from "market-oriented direct purchase users" or "market-oriented retail users "" is changed to "agent electricity purchase user" is the third time when the label becomes effective, and at the same time, the "whether delisted without justified reasons" in the market attribute judgment field is changed from "no" to "yes", and the third time when the label becomes effective The timestamp when the update field takes effect.

Through the online data interaction mechanism between the power grid enterprise and the trading center, the present invention constructs a market-oriented state representation with time scale for industrial and commercial users. Within a certain period of time, the market-oriented state representation uniquely corresponds to the electricity consumption information of industrial and commercial users , so as to make full use of market-oriented state representations to identify user information and handle related businesses. Faced with tens of millions of power users, the efficiency of power grid enterprises in maintaining the market-oriented attributes of power users has been improved.

Step 2. When settling the electricity bills generated by industrial and commercial users in the historical time period [t _m , t _n ] at time point T, use the sliding time window to monitor the time t _i when the marketization state representation of industrial and commercial users changes one by one, i= 1,2...N; where, t _m <t _i <t _n <T, N is the total number of time.

Use the time t _i to divide the historical time period [t _m ,t _n ] into multiple sub-time periods, and use the effective marketization attribute labels and effective marketization attribute discrimination fields in each sub-time period to determine the corresponding sub-time period The marketization state characterization of industrial and commercial users in China.

Specifically, step 2 includes:

Step 2.1, for the historical time period [t _m ,t _n ] of industrial and commercial users, use the sliding time window to monitor the time t _i when the marketization state representation of industrial and commercial users changes one by one, i=1,2...N;

In any sliding time window, if the marketization attribute label or any marketization attribute discrimination field changes, it is determined that the commercial user's marketing state representation in the sliding time window changes;

In any sliding time window, although the marketization attribute label and any marketization attribute discrimination field are changed, but the marketization attribute label is invalid or any marketization attribute discrimination field is invalid, then the market of commercial users in the sliding time window is determined Changes in the representation of the chemical state;

Among them, the effective time scale and label failure time scale of the market-oriented attribute label are compared with the sliding time window to determine whether the market-oriented attribute label is invalid in the sliding time window, and the field effective time scale and The field failure time scale is compared with the sliding time window to determine whether any marketing attribute discriminant field is invalid within the sliding time window.

Step 2.2, use the time t _i to divide the historical time period [t _m ,t _n ] into multiple sub-time periods [t _m ,t ₁ ], [t ₁ ,t ₂ ], ..., [t _i ,t _{i+ 1} ],..., [t _N ,t _n ];

In step 2.3, use one effective marketing attribute label and three effective marketing attribute discrimination fields in each sub-time period to determine the marketization state representation of industrial and commercial users in the corresponding sub-time period.

The marketization status of industrial and commercial users in each sub-period is unique.

The market-oriented state representation proposed by the present invention is based on the continuous state quantity of the user's power consumption state based on the time axis, and is closely connected with the electricity bill settlement, realizing the synchronization of the market-oriented attribute change of the power user and the electricity bill settlement in time, which is beneficial to the electricity bill The real-time promotion of settlement work reduces the risk of electricity bill prevention and control of power grid enterprises, reduces the error rate of user electricity bill settlement, and supports the efficient operation of power grid enterprises and trading centers.

Step 3, within each sub-period, determine the user's electricity price according to the marketization state representation of the industrial and commercial users.

Specifically, in any sub-period, when the marketization attribute label of the industrial and commercial user takes effect and is "agent electricity purchase user" or "registered non-trading user", the corresponding value of the marketization attribute label is 10, when the industrial and commercial user When the marketization attribute label of the user takes effect and is a "marketization direct purchase user" or "marketization retail user", the corresponding value of the marketization attribute label is 00; when the marketization attribute label of the industrial and commercial user fails, the marketization attribute label The corresponding value is 00.

In any sub-period, when the three marketization attribute discrimination fields of industrial and commercial users are all in effect and at least one of the marketization attribute discrimination fields is "Yes", the corresponding value of the marketization attribute discrimination field is 01. When all the marketization attribute discrimination fields are valid but at least one marketization attribute discrimination field is “No”, the corresponding value of the marketization attribute discrimination field is 00; The value corresponding to the discrimination field is 00.

The value corresponding to the marketization state representation of industrial and commercial users is the sum of the value corresponding to the effective marketization attribute label and the value corresponding to the effective marketization attribute discrimination field.

When the corresponding value of the marketization state representation of industrial and commercial users is 11, the user’s electricity price is 1.5 times the agency purchase price; when the corresponding value of the marketization state representation of industrial and commercial users is 10, the user’s electricity price is the agency purchase price; When the corresponding value of the marketization state representation is 01 or 00, the user's electricity price is the user's contract price.

Step 4: Settle the electricity charges of the industrial and commercial users in the historical time period [t _m , t _n ] by using the user electricity prices in each sub-time period.

分别表示子时间段[t_m,t₁]的用户电价、子时间段[t₁,t₂]的用户电价、子时间段[t_i,t_it1]的用户电价、子时间段[t_N,t_n]的用户电价。In the formula,

Respectively represent the user electricity price in the sub-time period [t _m ,t ₁ ], the user electricity price in the sub-time period [t ₁ ,t ₂ ], the user electricity price in the sub-time period [t _i ,t _it1 ], the user electricity price in the sub-time period [t _N ,t _n ] user electricity price.

On the other hand, the present invention also proposes a system for linking the change of market-oriented attributes of industrial and commercial users and the settlement of electricity bills, including: a market-oriented state representation module, a user electricity price module, and an electricity bill settlement module;

The marketization state characterization module is used to generate a unique marketization state representation for industrial and commercial users; the determinants of the marketization state representation include: a marketization attribute label, three marketization attribute discrimination fields; When the electricity bill generated in the historical time period [t _m ,t _n ] is settled, the sliding time window is used to monitor the time t _i when the marketization state representation of industrial and commercial users changes one by one, i=1,2...N; where, t _n < t _i <t _n <T, N is the total number of times; use the time t _i to divide the historical time period [t _m ,t _n ] into multiple sub-time periods, and use the effective market-oriented attribute labels and effective marketization attribute discrimination field to determine the marketization status representation of industrial and commercial users in the corresponding sub-time period;

The user electricity price module is used to determine the user electricity price according to the marketization state representation of industrial and commercial users within each sub-period;

The electricity fee settlement module is used to settle the electricity fee of industrial and commercial users in the historical time period [t _m , t _n ] by using the user electricity price in each sub-time period.

The beneficial effect of the present invention is that, compared with the prior art, it can support power grid enterprises to accurately and clearly store the market-oriented attributes of power users, efficiently and smoothly carry out information data interaction with power trading centers on market-oriented attributes of power users, and effectively transfer power The user's market-oriented attribute change is connected with the electricity bill settlement work.
