摘要： The present disclosure discloses a method and apparatus for measuring carbon emission of a district heating system, an electronic device, and a medium. The method includes: obtaining a steady carbon emission amount of a current district heating system using a pre-trained steady carbon emission flow model; obtaining a dynamic carbon emission amount of the current district heating system using a pre-trained dynamic carbon emission flow model; and counting a carbon emission amount of the current district heating system based on the steady carbon emission amount and the dynamic carbon emission amount. Therefore, the present disclosure can effectively identify carbon emission details of each link of a source, a grid, and a load of the district heating system, clarify carbon emission responsibilities on both a source side and a load side, and realize accurate measurement of carbon emission of the district heating system, which has high application value.

摘要： Provided is a carbon emission flow calculation method for a regional integrated energy system. The method includes: establishing a single-period steady-state carbon emission flow model of an energy conversion device by modeling carbon emission of each single-input-single-output conversion device and each single-input-multi-output conversion device; obtaining a matrix expression of carbon emission flow based on the single-period steady-state carbon emission flow model of the energy conversion device and establishing a single-period steady-state carbon emission flow model of the regional integrated energy system; and establishing a standardized multi-period carbon emission flow model of the regional integrated energy system by combining a multi-period coupled steady-state carbon emission flow model of energy storage devices and the single-period steady-state carbon emission flow model of the regional integrated energy system, to obtain actual carbon emission flow of the regional integrated energy system by solving the standardized multi-period carbon emission flow model.

摘要： The present disclosure provides a system for measuring carbon emissions in a power system. The system includes: generation carbon meters, distributed respectively in generators in the power system; network carbon meters, distributed respectively in nodes in the power system; consumption carbon meters, distributed respectively in consumers in the power system; and a center server, in which each carbon meter is configured to collect data for measuring the carbon emissions. The center server is configured to acquire the collected data and to measure the carbon emissions according to the acquired data, and to send measuring results to the corresponding carbon meter. Then each carbon meter is further configured to display according to the measuring results. The carbon emission may be measured in real time.
