One of the tools provided to the farmers is solar minigrid technology from Sunnova, which is being used to power off-grid irrigation systems at three newly established farms in Aweil, South Sudan. Minigrids, which are sometimes referred to as remote microgrids, are typically used in remote areas that do not have access to a central grid.

READ MOREThe function of microgrid control is of three sections: (a) the upstream network interface, (b) microgrid control, and (c) protection, local control. Microgrid control is assessed in many studies, and it can be grouped based on the tree diagram, Figure 8. This classification has been performed based on the studies found in the literature.
