AI Technical Summary

Technical Problem

Existing methods for analyzing carbon emission flows in power systems require obtaining power flow information for the entire network at once. However, the accuracy and comprehensiveness of power flow information from distribution networks and microgrids are not perfect, resulting in large measurement errors and failing to meet the internationally recognized "three-fold" principle of carbon measurement (measurable, reportable, and verifiable).

Method used

A centralized-distributed collaborative carbon emission measurement method is adopted. By collecting the topology, power flow distribution and historical carbon emission data of the transmission and distribution networks, a carbon measurement system architecture is constructed, including centralized and distributed carbon measurement system modules. The centralized module calculates the carbon emission factor of the transmission network nodes and sends it to the distributed modules for local iterative calculation. A local coordination mechanism is established between the distributed modules, and the data is finally integrated and stored by the centralized module.

Benefits of technology

This technology enables the application of carbon emission measurement for electricity users, solving the problems of existing technologies. It achieves real-time calculation of carbon emissions from electricity consumption, improves the spatiotemporal resolution of carbon emission analysis, meets the requirements of measurability, reportability, and verifiability of carbon metering, and reduces metering costs.
