Applications and Prospects of Digital Technologies in Source-Grid-Load-Storage Coordination

The integration of a high proportion of renewable energy sources and the pursuit of carbon peaking and carbon neutrality present both new opportunities and challenges for power systems. One of the primary characteristics of a new power system is the efficient coordination among power generation, grid, load, and energy storage. A crucial pathway towards the development of source-grid-load-storage coordination involves the deep integration of advanced digital technologies with grid operations. This article explores the application of digital technologies in source-grid-load-storage coordination from three critical perspectives: precise sensing, efficient utilization and sharing of data, and intelligent analysis and operational control of power systems. The insights provided in this article can serve as references for the profound integration and application of digital technologies in the construction of the new power system.
