Description
Technical Field
The embodiment of the invention relates to the technical field of electric power, in particular to a method and a system for improving the participation enthusiasm of interruptible loads in demand response.
Background
At the present stage, renewable energy sources such as wind power and the like are vigorously developed in China to realize adjustment of energy source structures. However, the inverse peak regulation characteristic of wind power and the power demand continuously increase during the peak load period, which increases the peak regulation burden of the system. Accordingly, power systems have developed a demand response technology to relieve system power stress, which requires reliable, efficient, and quick response to users participating in interruptible load programs when the system power is in tension.
Existing demand side response (DR) strategies are largely divided into two categories: price based and incentive based. Among them, the price-based DR is divided into time-of-use electricity prices, peak electricity prices, and real-time electricity prices. The time-of-use electricity price is a common electricity price strategy in China, can effectively reflect an electricity price mechanism of power supply cost difference of a power grid in different periods, and mainly takes measures of properly increasing the electricity price in a peak period, properly reducing the electricity price in a valley period, reducing load peak-valley difference, improving electricity consumption of users and achieving the effects of peak clipping and valley filling.
Load management is an important aspect in demand side response, and can improve the electricity utilization habits of users through regulating and controlling demand side loads, so as to achieve the aims of reducing the maximum load of a power grid, reducing the installed capacity of a system and reducing the operating cost. Peak clipping refers to reducing the load demand of a power grid in a peak period, valley filling refers to increasing the utilization level of idle power generation capacity of a system, and peak shifting and valley filling refers to adjusting the load using mode in the peak-valley period.
However, the user response process is influenced by external environmental factors and the user's own decision, so that uncertainty exists in the actual response. With the popularization of interruptible load projects, the operating risk of the power system is increased to a certain extent due to uncertainty, and the factors are not comprehensively considered by the DR based on the incentive at present, so that the enthusiasm of interruptible load users for participating in demand response is low.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Demand Response (DR) is an abbreviation of power Demand Response, which means that when the price of a wholesale market of power is increased or the reliability of a system is threatened, a power consumer receives a direct compensation notification of inductive load reduction sent by a power supplier; or after the power price rising signal, the inherent conventional power mode is changed, and the purpose of reducing or shifting the power consumption load in a certain period of time to respond to the power supply is achieved, so that the stability of the power grid is guaranteed, and the short-term behavior of the power price rising is restrained. DR is one of the solutions for Demand Side Management (DSM).
The DR based on the incentive means that a DR implementation mechanism formulates a corresponding policy according to the supply and Demand conditions of the power system, and a user reduces the power Demand when the system needs or the power is in tension, so as to obtain Direct compensation or preferential power rates in other periods, including Direct Load Control (DLC), Interruptible Load (IL), Demand Side Bidding (DSB), Emergency Demand Response (EDR), capacity market items, auxiliary service items, and the like. There are generally two ways in which a participating user may obtain an incentive: firstly, the direct compensation independent of the existing electricity price policy is realized; and discount is given on the basis of the existing electricity price. Before the demand response plan is implemented, the DR implementation organization usually enters into a contract with the participating users in advance, contracts the content of the demand response (reduction of the size of the electric load and the accounting standard, the response duration, the maximum response times in the contract period, and the like), notifies the time in advance, the compensation or price discount standard, and the penalty measure of the default, and the like.
In order to effectively mobilize the enthusiasm of the user for participating in the demand response, the incentive fee and the penalty fee of the user can be adjusted. The embodiment of the present invention provides a method for improving the participation enthusiasm of interruptible load in demand response, as shown in fig. 1, including but not limited to the following steps:
step S1: collecting actual response data of all signed interruptible load users participating in demand response;
step S2: determining a user reputation evaluation index;
step S3: calculating actual response data by using the user credit evaluation index, and establishing a response credit set after acquiring the response credit of each user;
step S4: and re-determining the incentive fee and the penalty fee of each user according to the response credibility set.
The collected actual response data refers to data which are collected by interruptible load users who have signed a contract with a power supplier in advance to participate in demand response and participate in demand response within a preset historical time period. The participation of each user in the past interrupt events can be known through the data.
Further, in the embodiment of the present invention, a reputation degree evaluation index of the user may be formulated according to the nature of the demand response, and the reputation degree evaluation index may be used to analyze the collected actual response data to obtain the reputation degree of each signed user.
For example: a total of 10 interrupt events occurred within a preset statistical time period. When the above interruption event occurs, a subscriber a participates in 6 times in total, and a subscriber B participates in 8 times in total, then it can be determined that: the reputation of subscriber B is greater than the reputation of subscriber a. The following steps are repeated: if the times of participation of the subscriber A and the subscriber B are the same, but the subscriber B correspondingly reduces the size of the electric load according to the contract requirement in each response process; however, if the user a reduces the magnitude of the electrical load in a certain response process to meet the contract requirement, it can also be determined that the reputation of the contracting user B is greater than that of the contracting user a.
It should be noted that, in the embodiment of the present invention, no specific limitation is made on the user reputation evaluation index, and all indexes that affect the demand response effect may be used as the user reputation evaluation index.
Further, the determined user reputation evaluation index is used to perform quantitative calculation on the actual response data of each user collected in step S1, and after the response reputation corresponding to each subscriber is determined, a response reputation set is constructed.
Furthermore, different incentive fee and punishment fee grades can be worked out according to the response credit set and the response credit of the signed user for the demand response in a gradient manner. Finally, the grade of the response credit degree of each user is determined so as to determine the incentive fee and the penalty fee when the user signs the contract next time.
According to the method for improving the initiatives of the interruptible load participation demand response, provided by the embodiment of the invention, the actual response data of the users are analyzed, the incentive cost and the punishment cost of each user when the next contract is signed are re-determined, and the initiatives of the users for participating in the demand response are effectively stimulated, so that the risk of large uncertainty of the demand response of the power system caused by the fact that the users do not make decisions to participate in the response is reduced, and the safety and the reliability of the system operation are improved.
Based on the content of the foregoing embodiment, as an option, in the method for improving the enthusiasm for interruptible load participation in demand response provided by the embodiment of the present invention, determining the user reputation degree evaluation index may include: determining a reputation point calculation formula of a user participating in incentive type demand response; determining the total credit points of all interruption events of the user in the statistical period according to a credit point calculation formula; and determining a user reputation evaluation index according to the ratio relation between the total reputation of each user and the excitation response reputation integral reference value.
Specifically, in the embodiment of the present invention, the determining of the user reputation evaluation index may be determining, according to the property of the demand response, related parameters that affect the efficiency of the demand response and the weight of each parameter, and further determining a calculation formula for calculating the reputation score of the user participating in the incentive type demand response. And then, determining a calculation period, for example, taking one year as the calculation period, and the like, acquiring the interruption events occurring in the time period, calculating the credit points of each user according to the data of the participation of each user in the demand response when each interruption event occurs, and accumulating to determine the total credit points of each user. And then, determining an excitation response reputation integral reference value in a calculation period, dividing the total reputation of each user by the excitation response reputation integral reference value, and acquiring a ratio relation of the total reputation of each user and the excitation response reputation integral reference value to serve as a reputation evaluation index of each user.
The method for improving the interruptible load participation demand response enthusiasm provided by the embodiment of the invention determines a method for determining the reputation evaluation index of the user, is used for scientifically analyzing actual response data so as to obtain the reputation evaluation index for measuring each signed user, provides a method for analyzing discrete data, and provides a calculation basis and a theoretical basis for implementing the method for improving the interruptible load participation demand response enthusiasm.
Based on the content of the foregoing embodiment, as an optional embodiment, in collecting actual response data of all signed interruptible class load users participating in demand response, the actual response data may specifically include: in the interruptible event, the load reduction amount of the user under the contract and the actual load reduction amount of the user are reduced.
Since the load reduction amount is the most capable of measuring the enthusiasm of the user for participating in the demand response, in the embodiment of the invention, the collected actual response data is set as the load reduction amount of the user under the contract and the actual load reduction amount of the user under each occurrence of the interruptible event. The credit degree of each user can be determined by the difference between the actual load reduction amount and the load reduction amount.
Alternatively, if the difference between the actual load reduction amount and the contractually specified load reduction amount for a total of three interruptible events for user a is: -10KW, 0KW, and-90 KW; the difference values of the user B are: 0KW, and-20 KW; and respectively summing the difference values of the two users, so that the total difference value of the user A is-100 KW, and the total difference value of the user A is-20 KW. Dividing the difference value by a difference value reference value respectively, if 800KW is adopted, the credit degree coefficient of the user A is-12.5%, and the credit degree coefficient of the user B is-2.5%, and comparing the two values, the following can be obviously obtained: the credit coefficient of the user B is larger than that of the user A, so that compared with the user A, the incentive cost of the user B can be properly increased and the punishment cost of the user B can be reduced when the user A signs a contract next time, so that the incentive effect is achieved, and the enthusiasm of the user A and the user B is improved.
According to the method for improving the enthusiasm of interruptible load participation in demand response, the load reduction amount specified by the contract and the actual load reduction amount of the user are determined to be used as actual response data for observing the demand response of the user, and the excitation accuracy is improved on the premise of effectively simplifying the modeling complexity.
Based on the content of the above embodiment, as an alternative embodiment, the reputation score calculation formula is:
wherein, Fi,mRepresenting the credit score of the ith user in the mth interruption event in the statistical period; k is a radical of1、k2、k3And k4Respectively is the conversion proportion between the credit integral and the load of the user under the four response conditions in the mth interruption event;
indicating that in the m-th interruption event, the load reduction amount of the i-th user under the contract is reduced,
indicating the actual load reduction amount of the ith user in the mth interrupt event; u denotes the fluctuation range of the interruptible load curtailment power allowed by the power provider.
The four response conditions refer to the positive degree of participation in demand response after the user has occurred to the interrupt event, and may include: excellent, good and general and bad. It should be noted that the above calculation formula is only considered from the viewpoint of simplifying the calculation degree, and the situations of user participation in demand response are simply divided into four types in a large aspect, and may also be divided into more or fewer types according to the actual operation needs, such as: the term "excellent" is divided into very excellent and generally excellent, and the examples of the present invention are not limited to the cell.
Further, the calculation formula of the total reputation integral is shown in formula 2:
wherein, FiAnd the total credit points accumulated after the ith user counts M interruption events in the counting period are obtained.
As an alternative embodiment, the step S2 may specifically include the following steps:
step S2.1, determining the credit points of each user participating in the incentive type demand response: in the mth interruption event in the statistical period, the integral calculation formula of the user i is shown as formula 1;
step S2.2, determining the total credit points of each user in the interruption events for M times in the statistical period, as shown in formula 2;

the response credit degree of the ith user in the statistical period is obtained; fiThe total credit score of the ith user is integrated; fi,GZAn incentive response credit benchmark value for the ith user; n is a radical ofIThe total number of interruptible class users participating in the demand response.
Further, in the embodiment of the present invention, the calculating of the actual response data by using the user reputation evaluation index, and after obtaining the response reputation of each user, establishing the response reputation set may specifically include: respectively calculating the total credit integrals of all the users in the statistical period and after all the interruption events according to the actual response data; and building the total reputation points of the users into a response reputation set.
The set of response reputations a may be represented by equation 4 as follows:
wherein N isIIs the total number of interruptible class users participating in the incentive-type demand response.
Based on the above embodiments, as an alternative embodiment, the re-determining the incentive fee and the penalty fee of each user according to the set of the response reputations may include: dividing the user response credit into different gradients according to the response credit set, and comprehensively determining the load excitation cost and the punishment cost of each gradient; and determining the excitation cost and the punishment cost of each user according to the gradient of the response credit degree of each user.
Further, the reputation degree of the user response is divided into different gradients according to the set of reputation degrees of the response, specifically, the reputation degree of the user response is divided into four gradients, i.e. excellent, good, general and bad, which are expressed as:
wherein Q is1、Q2、Q3Respectively, dividing threshold values for different gradients, and Q1>Q2＞Q3(ii) a p represents the rating of the reputation rating of the user response.
Specifically, as an alternative embodiment, the step may include, but is not limited to, the steps of:
step S4.1, divide the reputation of the user response into four gradients of excellent, good and general and bad, as shown in formula 5: .
Wherein Q is1、Q2、Q3The values of the user response credit degree are respectively set to be 90%, 75% and 60%, and p represents the grade of the user response credit degree division.
And 4.2, respectively making four gradient load excitation fees and penalty fees according to the user response credit degrees, as shown in a formula 6 and a formula 7. Wherein the lower the load gradient, the lower the load excitation cost and the higher the penalty cost.

The method for improving the interruptible load participation demand response enthusiasm provided by the invention evaluates the user credit degree in the statistical period, and is favorable for the scheduling and planning personnel to further know the actual response condition of the interruptible user. After the credibility of the user response is evaluated, the system is also favorable for screening out users with poor credibility, so that the risk of large uncertainty of the demand response of the power system caused by the fact that low-credibility users do not participate in the response when a power supplier sends an interrupt signal is reduced. In addition, the credit level of the user response is brought into the examination, the incentive and punishment cost of each user is set by gradient, so that the enthusiasm of the user for participating in the demand response is provided, and the risk of large uncertainty of the demand response of the power system caused by the fact that the user decides not to participate in the response when a power supplier sends an interrupt signal can be effectively reduced.
