Abstract

The invention relates to an electric power system carbon emission real-time measuring method and a carbon meter system and belongs to the electric power system low-carbon technical field. The method includes the following steps that: the basic index of the carbon emission flow of an electric power system is determined; corresponding initial data are generated according to power flow distribution in an electric power network, the injection power of power plants and the topological structure data of the network; the carbon emission flow of the electric power network is calculated according to the obtained initial data; and the carbon potential of each node, branch carbon flow rates and corresponding load carbon flow rates can be obtained. The carbon meter system is composed of carbon meters which are dispersed at various positions of China, a central server and communication lines connected with the carbon meters and the central server, wherein the carbon meters are divided into power generation-side carbon meters, network-side carbon meters and user-side carbon meters, wherein the network-side carbon meters is composed of power transmission network carbon meters and power distribution network carbon meters. With the electric power system carbon emission real-time measuring method and the carbon meter system of the invention adopted, real-time continuous measurement of the carbon emissions of different main bodies of the electric power system can be realized.

Description

technical field [0001] The invention belongs to the low-carbon technical field of power systems, and in particular relates to a method for real-time measurement of carbon emissions in a power system and a carbon meter system. technical background [0002] Issues such as the energy crisis and global climate change have aroused people's increasing concern. Reducing the excessive consumption of fossil fuels and realizing low-carbon development has become the common goal of all industries in all countries. As an important part of energy supply, the power industry is also a major industry that consumes fossil fuels, resulting in a large amount of carbon emissions. Since my country's power source structure is dominated by coal-fired thermal power, this phenomenon is particularly significant in my country. According to statistics, in recent years, the carbon dioxide emitted by my country's power industry accounts for about half of the country's carbon emissions caused by fossil f...

Problems solved by technology

The existing macro-statistical method attributes all carbon emissions to the power plant level, which cannot reflect the network characteristics of the power system and ignores the flow and distribution of carbon emissions from "source" to "exit".

Moreover, it is impossible to realize real-time measurement of carbon emissions, and it is also impossible to intuitively display the carbon emissions caused by users' electricity consumption.

Therefore, it is not conducive to power users to respond to real-time carbon emissions, and to reduce carbon emissions by adopting low-carbon electricity consumption measures
