Description

Technical Field

[0001] The present invention relates to the technical field of integrated energy carbon flow analysis, and in particular to a method and device for evaluating carbon emission levels of an enhanced micro-energy grid integrated energy system. Background Art

[0002] The carbon emission flow related indicators in the energy flow network of the integrated energy system are called carbon flow indicators. Currently, the commonly used carbon flow indicators include carbon flow, carbon flow rate, carbon flow density, etc. Among them, carbon flow is the cumulative amount of carbon emissions corresponding to the carbon flow that follows the energy flow through a branch or node over a period of time, which can characterize the size of the carbon emission flow on the branch or node. In terms of numerical values, the carbon emission flow of a branch or node should be the total amount of carbon dioxide emitted by the production side to maintain a given energy flow of the branch or node, including the actual carbon emissions generated by a certain production node in the system and the carbon emissions from the production side of the system or external sources related to the consumption of various energy sources by the node. The unit is kgCO 2 The carbon flow rate is the carbon emission flow rate of a branch or node passing through the energy flow in unit time, referred to as the carbon flow rate, and the unit is kgCO 2 / h. Carbon flow density is also called carbon intensity, which indicates the carbon emission on the production side corresponding to the energy generated by each node or flowing through each branch. It is the ratio of the carbon emission flow rate of the node or branch to the active power, and the unit is kgCO 2 / (kW·h). In the power system, node carbon potential generally refers to the carbon emissions on the power generation side caused by the generation or transmission of unit electric energy at the node.

[0003] The existing public patent document CN116526488A discloses a carbon flow analysis method for a power system with distributed power generation access. The carbon flow analysis model in this method belongs to a static carbon emission accounting model for the power grid. It averages the carbon emissions in a certain period of time according to the power at each node to obtain a node carbon emission intensity index, also known as node carbon potential. This method, combined with the carbon flow analysis method, can calculate the carbon emission intensity per kilowatt-hour at different times, different nodes and branches of the power grid. It can be applied to the fields of carbon emission responsibility sharing, carbon emission reduction operation, and low-carbon planning of power systems. However, this method cannot make an overall evaluation of the overall level of carbon emissions of the multi-energy coupled integrated energy system, nor can it reflect the overall level of equivalent carbon emissions on the production capacity side related to the comprehensive energy supply required by the various heterogeneous loads of each user on the load side.

BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 It is a flow chart of the carbon emission level evaluation method of the enhanced micro-energy grid integrated energy system according to the first embodiment of the present invention. DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0026] The first embodiment of the present invention relates to a method for evaluating the carbon emission level of an enhanced micro-energy grid integrated energy system. This embodiment is aimed at an enhanced micro-energy grid with electricity as the core, and defines carbon potential as the carbon intensity corresponding to the energy flowing into or out of a node per unit time, that is, the carbon potential is used to represent the carbon emissions on the production capacity side related to the consumption, output, charging, or release of unit energy at a certain node. Among them, the enhanced micro-energy grid is a new type of micro-energy grid that has the ability to efficiently gather and control comprehensive energy internally, has the ability to interact efficiently with the power grid, and has the ability to interconnect and radiate with a radius of tens of kilometers in the surrounding area. The total carbon potential of a certain type of energy flow input by its node is numerically equal to the weighted average of the carbon flow density of all similar energy flow branches flowing into the node with respect to the functional flow, which can be expressed as:

[0027] ;

[0028] In the formula, For branch The functional flow, For branch The carbon flow density, For Node The nodal carbon potential of For branch A collection of .

[0029] According to the above carbon flow analysis method, the carbon potential of the node output energy flow is determined according to the carbon diversion principle, among which the carbon potential of the node output homogeneous energy flow is equal, and the carbon potential of the output heterogeneous energy flow is related to the heterogeneous energy flow diversion ratio, which is the ratio of the carbon emissions related to the node output of a single heterogeneous functional energy flow to the output energy per unit time.

[0030] The definition of carbon potential can make the upstream carbon emissions caused by the conversion or transfer of energy at each downstream node in the system equivalent to the capacity side, that is, the carbon potential is used to represent the equivalent carbon emission value on the capacity side related to the node's consumption, output, charging, or release of unit energy. For a capacity node, its carbon potential is equivalent to the carbon emission intensity of the capacity equipment at the node.

[0031] like Figure 1 As shown, the enhanced micro-energy grid integrated energy system carbon emission level evaluation method of this embodiment includes the following steps:

[0037] The daily average carbon potential of a single heterogeneous load can be calculated through the calculation model of the daily average carbon potential of a single heterogeneous load. This indicator is used to describe the comprehensive level of carbon emissions on the upstream energy supply side caused by the consumption of various heterogeneous loads on the demand side in a typical day. Its value is the time-weighted average carbon potential of the heterogeneous loads such as cold, heat, and electricity in each control period in a typical day.

Its value is the seasonal average carbon potential of the three loads of cold, heat and electricity in each energy supply season scenario, weighted by the proportion of typical days in the season.

[0042] The calculation model of annual average carbon potential of single heterogeneous load is:

[0043] ;

[0044] in, Single heterogeneous load The annual average carbon potential of For energy supply season scene A collection of .

[0045] The annual average carbon potential of a single heterogeneous load can be calculated through the annual average carbon potential calculation model. This indicator is used to describe the comprehensive level of carbon emissions on the upstream energy supply side caused by the consumption of various heterogeneous loads on the demand side over an inter-annual time span. Its value is the annual average of the typical daily average carbon potential of the three loads of cold, heat and electricity, weighted by the proportion of typical days in the whole year.

[0046] Step 2: construct a multi-energy coupling comprehensive carbon potential index calculation model for heterogeneous loads based on the single heterogeneous load carbon potential index, and calculate the multi-energy coupling comprehensive carbon potential index of the heterogeneous load according to the multi-energy coupling comprehensive carbon potential index calculation model for the heterogeneous load.

It includes the multi-energy coupling typical daily root mean square carbon potential calculation model, the multi-energy coupling energy supply quarterly root mean square carbon potential calculation model and the multi-energy coupling annual root mean square carbon potential calculation model.
