Abstract:Regarding the common challenges in the current integrated regulation of Source-Grid-Load-Storage system, such as the lack of an integrated regulation strategy for "new energy + large-scale energy storage", insufficient proactive support capability, and multiple system frameworks, a study was conducted using the first national "Source-Grid-Load-Storage" integrated project as a case to explore an integrated regulation management model. The study focused on technical innovations such as regional wind and solar power joint prediction, the key mechanism of the "grid-source" coordination for grid-friendly new energy power plants, collaborative optimization control and protection of wind and solar storage stations, rapid primary frequency regulation of new energy, and virtual inertia support. In addition, the study also conducted research and development on the integrated data centralized control platform for wind and solar storage stations, innovative "centralized control + direct control" dual scheduling modes, and full-chain research and development management innovation. The results show that the integrated centralized control platform provides data support for the source-grid-load-storage integrated operation from four aspects: measurability, controllability, adjustability, and supportability, meeting the requirements of smart control, grid-friendly connection, and stable operation of wind and solar energy storage stations, and achieving the goals of panoramic intelligence, grid-friendly operation, and collaborative wind and solar storage. The research results can provide support for accelerating the construction of Source-Grid-Load-Storage system, innovating integrated regulation management models, and promoting the formation of standardized implementation paths for Source-Grid-Load-Storage system.
