“One Graph of Electricity Carbon” Spatiotemporal Data Analysis and Management System

The current electricity carbon emission analysis and management methods lack timeliness. The calculation does not consider the developmental differences in energy generation types and quantities in different regions, the time-varying characteristics of power generation, and the power flow transmission in the power grid. The management system lacks an intuitive reflection of regional electricity carbon intensity’s spatial and temporal evolution. This paper proposed a time-sharing and partitioned electricity carbon intensity calculation method based on the coupling analysis of power and carbon flow. Using graph database and graph computing, this paper introduced the construction process of the “one graph of electricity carbon” spatiotemporal data analysis and management system and provided various visualization solutions and application scenarios in a provincial power grid. This system realized the automatic division of different regions, precise calculation of carbon intensity, and carbon flow tracking.
