The invention is realized by the following technical scheme: a method for carbon emission reduction metering at the power utilization side of a transformer area comprises the following steps:
s1: acquiring the node carbon potential of the distribution network node of the distribution area,Electric quantity of new energy output in the transformer area and electric quantity consumed in the transformer area are as follows: the node carbon potential refers to carbon emission equivalent to the power generation side caused by unit electricity consumption of the node, and the unit is generally KgCO 2 and/Kwh, and for a power supply node, the node carbon potential is equivalent to the real-time power generation carbon emission intensity of a power plant. In addition, the consumed electric quantity of the distribution area refers to the electric quantity consumed by the power utilization side of the distribution area, and can be a positive value or a negative value, and when the consumed electric quantity is the positive value, the new energy does not exist in the distribution area or the new energy output is insufficient to support the electric quantity required by the load in the distribution area, the distribution network is used as an external power supply to transmit the electric quantity to the distribution area; when the output of the new energy in the distribution area is negative, the output of the new energy in the distribution area is enough to support the electric quantity required by the load in the distribution area, and the surplus electric quantity is transmitted to the electric quantity of the distribution network. The consumed electric quantity of the distribution room can be obtained by reading a distribution room general table, and the process specifically comprises the following steps:
the main network can obtain the instantaneous carbon potentials of all nodes of the main network based on a carbon flow calculation technology, so that the distribution network nodes can obtain the instantaneous carbon potentials rho of the nodes of the main network corresponding to the distribution network nodes 1 And the generated power P provided by the main network node to the distribution network node is obtained from the acquisition equipment of the gateway of the distribution network node transformer substation 1 . In addition, unit power generation amount carbon cost accounting can be performed on each power supply node in the distribution network node, specifically, the instantaneous carbon potential ρ = [ ρ = [ ρ ] } of each power supply node is obtained 2 ，ρ 3 ，ρ 4 ，...，ρ n ]And obtaining the generated power P = [ P ] from the acquisition equipment of each power supply node in the distribution network node 2 ，P 3 ，P 4 ，...，P n ]. Then, neglecting the line impedance, the instantaneous carbon potentials of all nodes on the distribution network node line can be considered to be consistent, and according to the proportion sharing principle, the node carbon potential e of the distribution network node where the distribution area is located can be calculated as:
the network topology structure of the distribution network nodes is tree-shaped, radial or annular.
S2: obtaining the carbon emission of unit alternative energy of each electric energy alternative load in the transformer area: the specific process is as follows: the electric energy replaces the energy of the loadThe energy source is electric energy or other energy sources directly generating carbon emission, wherein the energy sources directly generating carbon emission mainly refer to fossil fuels. For example, the electric energy replacement load includes, but is not limited to: the heating system comprises an automobile using gasoline and electricity as energy sources, an automobile using diesel oil and electricity as energy sources, heating equipment using coal and electricity as energy sources, a dryer using coal and electricity as energy sources, heating equipment using natural gas and electricity as energy sources and the like. The carbon emission of the unit alternative energy refers to the carbon emission caused by the same effect corresponding to the unit electric energy generation when other energy directly generating carbon emission provides energy for the electric energy alternative load. For example, if an average one-hour electricity can drive an electric vehicle for 10 kilometers, 0.7L of gasoline needs to be consumed to drive the vehicle for 10 kilometers, and 1.6kg of carbon dioxide is generated from 0.7L of gasoline, the carbon emission per unit of alternative energy is 1.6KgCO 2 。
S3: the method comprises the following steps of obtaining the consumed electric quantity of each electric energy alternative load in a station area in the metering time, and calculating the carbon emission reduction quantity of each electric energy alternative load in the station area in the metering time by combining the obtained node carbon potential of a distribution network node where the station area is located, the electric quantity of new energy output in the station area, the consumed electric quantity of the station area and the carbon emission quantity of unit alternative energy of each electric energy alternative load, wherein the specific steps are as follows:

Adding the power consumption of the distribution area for 24 hours to obtain the total power consumption W of the distribution area in one day General (1) Then dividing the total carbon emission F of the transformer area in one day by the total consumed electricity W General assembly That is, the amount of carbon emission A generated on the power generation side per unit amount of electricity consumed in the platform area can be obtained, where A = F/W General (1) 。
And then subtracting the carbon emission A generated by unit electricity consumption in the platform area from the carbon emission B of the unit alternative energy of each electric energy alternative load to obtain the unit carbon emission reduction C, C = A-B of each electric energy alternative load.
Finally, multiplying the unit carbon emission reduction C of each electric energy replacing load by the electric quantity W consumed by each electric energy replacing load in one day x Namely, the carbon emission reduction W of each electric energy replacing load in the intra-day district can be calculated Reducing the weight of Wherein W is Reducing ＝C*W x 。
