Stem Cell Networking Technology 2.0 for Grid Security

This document introduces Stem Cell Networking Technology 2.0, a grid-forming solution designed to address stability challenges in modern power systems with high renewable energy penetration. It highlights issues like low inertia, low short-circuit ratio, and weak damping caused by photovoltaic and wind power integration. The technology provides multi-dimensional grid support on the AC side, dynamic energy optimization on the DC side, autonomous collaborative control at the station level, and full-link simulation capabilities. Verified by TÜV Rheinland, it includes project cases such as the Caipeng 20MW/80MWh storage in Tibet and the Hongyuan Anqu 50MW/100MWh project in Sichuan. The white paper discusses challenges like power angle, voltage, and frequency stability, as well as broadband oscillation, and offers solutions adapted to grid conditions for safe and stable operation.
