Abstract:
In response to the current challenges including the lack of regulation strategy for "new energy+large-scale energy storage, " insufficient proactive support capacity, and the presence of multiple systems, this paper takes the example of the first integrated "generation-grid-load-storage" project in the country to explore the application of an integrated control and management model. The main research contents include joint forecasting of regional wind and solar power, key coordination mechanisms between grid-friendly new energy power plants and the grid, coordinated optimization control and protection of wind and solar energy storage stations, technical innovations in rapid primary frequency regulation and virtual inertia support of new energy, as well as the development of an integrated data control platform for wind and solar energy storage stations and the innovation of a "centralized control + direct control" dual dispatching mode. The research results show that the integrated control platform provides data support for the integrated operation of generation, grid, load, and storage from the aspects of measurability, controllability, adjustability, and supportability, meeting the requirements for the integrated connection of new energy power plants and the stable operation of wind and solar energy storage. It has achieved the goals of panoramic intelligence, grid-friendliness, and coordinated operation of wind and solar energy storage. The research findings help accelerate the development of integrated generation, grid, load, and storage projects, and provide reference for the standardized implementation path of integrated generation, grid, load, and storage.
