Description

一种用户碳表计量数据的校核方法及系统A verification method and system for user carbon meter measurement data

技术领域Technical field

本发明涉及碳排放量的计量技术领域,特别涉及一种用户碳表计量数据的校核方法及系统。The present invention relates to the technical field of carbon emission measurement, and in particular to a verification method and system for user carbon meter measurement data.

背景技术Background technique

碳排放量的准确计量是掌握能源系统中各参与者排放贡献、明确减排责任的重要基础。随着碳流理论的发展,通过获得电源的碳排放强度,即可计算全网各节点的碳排放因子,由此可与用户的电能表结合起来,形成碳表,对用户能耗产生的碳排放量进行计量。Accurate measurement of carbon emissions is an important basis for understanding the emission contributions of each participant in the energy system and clarifying emissions reduction responsibilities. With the development of carbon flow theory, by obtaining the carbon emission intensity of the power supply, the carbon emission factors of each node in the entire network can be calculated. This can be combined with the user's electric energy meter to form a carbon meter, which can measure the carbon emissions generated by the user's energy consumption. Emissions are measured.

用户碳表对碳排放量的计量需要获取当前接入节点的碳排放因子,该因子可以是相关组织公布的年度平均值,也可以是由台区或调度中心进行下发、实时更新的动态区域平均值。然而,受到网络、通讯、延时等各方面的影响,导致碳表更新碳排放量结果时采用的碳排放因子数值可能出现编码错误、坏数据、未及时更新等情况,进而导致输出的碳排放量结果错误。The measurement of carbon emissions by the user carbon meter requires obtaining the carbon emission factor of the current access node. This factor can be the annual average published by the relevant organization, or it can be a dynamic area issued by the station area or dispatch center and updated in real time. average value. However, due to the influence of network, communication, delay and other aspects, the carbon emission factor value used when updating the carbon emission results of the carbon table may have coding errors, bad data, failure to update in time, etc., which will lead to the output carbon emissions. The measurement results are wrong.

目前碳排放的核算和校核主要针对的是煤电企业采用流量计或称重的方式对排放量进行确定,校核主要判断煤电企业排放量是否在允许范围内,缺乏对基于碳流理论的碳表计量结果进行校核的方法,可能导致用户碳排放量计算结果不准确。The current accounting and verification of carbon emissions is mainly aimed at coal power companies using flow meters or weighing methods to determine emissions. The verification mainly determines whether the emissions of coal power companies are within the allowable range. There is a lack of analysis based on carbon flow theory. The method used to check the measurement results of carbon meters may lead to inaccurate calculation results of users’ carbon emissions.

对于碳排放量的计算和获取,目前主要分为两类,一类是针对煤电企业的排放量进行核算,包括对煤粉进行称重、对燃烧排放用流量计进行检测计算排放量;一类是在此基础上,通过碳流理论,将发电部分的碳排放量分摊到用户身上。碳表利用节点碳排放因子和用户用电量计算用户的碳排放量,可以掌握各用户的排放贡献、明确减排责任。The calculation and acquisition of carbon emissions are currently mainly divided into two categories. One is to calculate the emissions of coal power enterprises, including weighing pulverized coal and measuring combustion emissions with flow meters to calculate emissions; Based on this, the carbon emissions from the power generation part are allocated to users through the carbon flow theory. The carbon meter uses node carbon emission factors and user electricity consumption to calculate the user's carbon emissions. It can understand the emission contribution of each user and clarify the responsibility for emission reduction.

现有技术中碳排放量的核算和校核均主要针对的是煤电企业排放量的核算及是否超标的校核,缺乏对于用户碳表计量结果的校核方法。The accounting and verification of carbon emissions in the existing technology are mainly aimed at the accounting of coal power enterprise emissions and verification of whether they exceed standards, and there is a lack of verification methods for user carbon meter measurement results.

具体实施方式Detailed ways

本申请实施例通过提供一种用户碳表计量数据的校核方法及系统,通过各用户碳排放量计算中间值并校验是否出现超差,如出现超差则计算新的碳排放量以修正原有结果,实现对用户碳表计量结果的校核。The embodiment of the present application provides a method and system for verifying user carbon meter measurement data, calculating the intermediate value through the carbon emissions of each user and verifying whether there is an out-of-tolerance. If an out-of-tolerance occurs, a new carbon emission amount is calculated to correct it. The original results can be used to verify the user's carbon meter measurement results.

本申请实施例中的技术方案,总体思路如下:采集各用户碳排放量计算中间值并校验是否出现超差,如出现超差则计算新的碳排放量以修正原有结果,实现对用户碳表计量结果的校核,从而能够识别网络、通讯、延时等引起的用户碳表碳排放量中的超差结果并进行纠正,弥补了当前用户碳表碳排放量缺乏校核方法的空白。其中,采集各用户碳排放量计算中间值并校验是否出现超差是指:利用网络参数及一个周期中各用户的碳排放量根据碳流理论反算多组中间量(包括各排放电源的碳排放强度、d轴和q轴的电流值);若存在异常的排放量计量值,则将导致其中某些组中间量计算结果异常,这样就存在一部分中间量正常值(或很接近正常值)和一部分中间量异常值(远离正常值的那一堆中间量),把中间量计算结果作为多维特征参量,采用支持向量机可将中间量正常值的类和异常值分开,并采用中间量正常值的平均值修正异常值,进而修正异常的用户碳排放量。The general idea of the technical solution in the embodiment of this application is as follows: collect the intermediate value of each user's carbon emission calculation and check whether there is an out-of-tolerance. If there is an out-of-tolerance, calculate a new carbon emission to correct the original result, so as to realize the user's Calibration of carbon meter measurement results, so that out-of-tolerance results in user carbon meter carbon emissions caused by network, communication, delays, etc. can be identified and corrected, filling the gap of the current lack of calibration methods for user carbon meter carbon emissions. . Among them, collecting the carbon emissions of each user to calculate the intermediate values and verifying whether there is an out-of-tolerance means: using network parameters and the carbon emissions of each user in a cycle to back-calculate multiple sets of intermediate quantities (including the emissions of each emission power source) based on carbon flow theory. Carbon emission intensity, current values of d-axis and q-axis); if there are abnormal emission measurement values, it will lead to abnormal calculation results of some groups of intermediate quantities, so that there will be some normal values (or very close to normal values) of the intermediate quantities. ) and a part of the intermediate quantity outliers (a bunch of intermediate quantities far away from the normal value), the calculation results of the intermediate quantity are used as multi-dimensional feature parameters, and the support vector machine can be used to separate the classes of normal values of the intermediate quantity from the outliers, and use the intermediate quantity The average of the normal values corrects the abnormal values, thereby correcting the abnormal user carbon emissions.

在介绍具体实施例之前,先介绍本申请实施例方法所对应的系统框架,如图1所示,系统大概分如下两个部分:Before introducing specific embodiments, first introduce the system framework corresponding to the method of the embodiment of this application. As shown in Figure 1, the system is roughly divided into the following two parts:

用户碳表,用于对用户的碳排放量进行计量,由于受到网络、通讯、延时等各方面的影响,导致碳表更新碳排放量结果时采用的碳排放因子数值可能出现编码错误、坏数据、未及时更新等情况,进而导致输出的碳排放量结果错误;The user carbon meter is used to measure the user's carbon emissions. Due to the influence of network, communication, delay and other aspects, the carbon emission factor value used when the carbon meter updates the carbon emission results may have coding errors or corruption. The data is not updated in a timely manner, which leads to incorrect output carbon emission results;

If an excess occurs, new carbon emissions are calculated to correct the original results and realize user carbon meter measurement. Calibration of results.

实施例一Embodiment 1

如图2所示,本实施例提供一种用户碳表计量数据的校核方法,包括下述步骤:As shown in Figure 2, this embodiment provides a method for verifying user carbon meter measurement data, which includes the following steps:

S101、获取当前区域电网所有用户碳表共n个当前更新周期的碳排放计量值C i ,i=1,2,…,n;S101. Obtain the carbon emission measurement values C i of all users' carbon tables in the current regional power grid for a total of n current update cycles , i =1,2,...,n;

其中,当前区域电网为技术应用者所关心的区域,大到某个省份或某个城市,或者小到某个社区或某个单位等。由于整个电网是互联的,理论上一个用户的碳排放因子与全国范围的火电厂都相关,这样会导致计算量过大,因此需要限制区域电网,在当前区域电网与其他区域电网相连的点或联络线进行等值,获得等值电源的碳排放强度。Among them, the current regional power grid is an area that technology users are concerned about, which can be as large as a certain province or a certain city, or as small as a certain community or a certain unit. Since the entire power grid is interconnected, theoretically a user's carbon emission factor is related to thermal power plants across the country. This will lead to excessive calculations. Therefore, it is necessary to limit the regional power grid. At the point where the current regional power grid is connected to other regional power grids or The tie lines are equalized to obtain the carbon emission intensity of the equivalent power supply.

S102、构建n−3m+1组碳排放计量值集合Z p, p=1,2,…,n-3m+1,m为当前区域电网中产生碳排放的电源的数量,m<<n,即选择第1~3m个碳排放计量值作为第1组碳排放计量值集合Z 1,并依次选择第2~3m+1、3~3m+2、…、n-3m+1~n个碳排放计量值作为第2、3、……、n−3m+1组碳排放计量值集合Z 2Z 3、……、Z n-3m+1S102. Construct n −3 m +1 sets of carbon emission measurement value sets Z p, , p=1,2,…, n -3 m +1, m is the number of power sources that produce carbon emissions in the current regional power grid, m<<n, that is, the 1st to 3m carbon emission measurement values are selected as the first group Set Z 1 of carbon emission measurement values, and select the 2nd to 3m+1, 3~3m+2,…, n -3 m +1~ n carbon emission measurement values as the 2nd, 3rd,…, n − 3 m +1 set of carbon emission measurement values Z 2 , Z 3 ,..., Z n -3m+1 ;

S103、针对每组碳排放计量值集合Z p 对应构成个方程组Θ p p=1,2,…,n-3m+1;S103. For each set of carbon emission measurement values Z p , a set of equations Θ p is formed, p =1,2,…, n -3 m +1;

;

其中:in:

C p+j-1为第p+j-1个用户的碳排放计量值; C p + j -1 is the carbon emission measurement value of the p + j -1th user;

T为碳排放因子更新周期;T is the carbon emission factor update cycle;

K本身无含义,仅为简化表达式的符号,上标p,j表示方程组Θp中的第j个方程中的变量;公式推导中可以将3m个变量归纳成如下的4个K:,/>,/>K itself has no meaning and is only a symbol for simplified expressions. The superscripts p and j represent the variables in the j-th equation in the system of equations Θp; in the derivation of the formula, the 3m variables can be summarized into the following 4 Ks: , ,/> ,/> ;

G p+j-1B p+j-1分别为第p+j-1个用户的等值电导和电纳,通过区域电网阻抗矩阵计算得到,区域电网阻抗矩阵从电网调度中心获得; G p + j -1 and B p + j -1 are the equivalent conductance and susceptance of the p + j -1th user respectively, which are calculated through the regional grid impedance matrix. The regional grid impedance matrix is obtained from the grid dispatch center;

分别为第p+j-1个用户与第k个电源之间的等值电阻和等值电抗,通过区域电网阻抗矩阵Kron降阶消去无源节点计算得到; They are the equivalent resistance and equivalent reactance between the p+j -1th user and the kth power supply respectively, which are calculated by eliminating passive nodes by reducing the order of the regional grid impedance matrix Kron;

分别为方程组Θ p 计算得到的第k个电源输出电流的dq轴分量; are respectively the d and q -axis components of the k -th power supply output current calculated by the equation system Θ p ;

S104、通过每个方程组Θ p 求解第p组中间量X p S104. Solve the p -th group of intermediate quantities X p through each system of equations Θ p :

;

每组中间量X p />和/>共3m个变量(k=1,2,…m),以及3m个方程,可通过数值方法或最小二乘方法求出唯一解;The middle amount of each group X p is , /> and/> There are a total of 3m variables (k=1,2,…m) and 3m equations, and the unique solution can be found through numerical methods or least squares methods;

S105、判断各中间量X p 是否出现超差,若是,则将超差中间量X s 对应的碳排放计量值集合Z s 修正为Z s ';其中,s为第s个超差中间量,s∈p。S105 . Determine whether each intermediate quantity X p is out of tolerance. If so, correct the set of carbon emission measurement values Z s corresponding to the out - of - tolerance intermediate quantity s∈p.

所谓的超差是指异常的排放量计量值,排放量计量值是否异常则取决于误差的要求,如对于误差为1%的碳表而言,计算结果偏离排放量计量值正常值均值的1%(或设置一定的裕度,如1.1%)就算异常。The so-called out-of-tolerance refers to an abnormal emission measurement value.
