Abstract: With the increasing number of domestic power grid projects in the source network load storage area, there are some technical problems in the isolated operation process of the "source network load storage" area power grid, and effective technical measures need to be taken to achieve the isolated, safe and stable operation of the regional power grid. This article proposes an integrated coordinated control scheme for source network load storage suitable for regional power grids. The entire system is divided into three levels of control, ensuring the stable and economic operation of the source network load storage system, and providing safe, stable, and reliable solutions for grid connected and independent source network load storage.
