distribution automation is a type of intelligent control over electrical power grid functions to the distribution level . The electrical power grid is typically separated into transmission systems and distribution systems. Electric power transmission systems operate above 110kV, whereas Electricity distribution systems operate at lower voltages. Normally, electric utilities with SCADA systems have extensive control over transmission-level equipment, and good control over distribution-level equipment. But Often unable to control smaller entities such as Distributed energy resources (DERs), buildings, and homes .Distributed generation is increasingly important in power grids around the world. This generation can help to support local power grids in the presence of blackouts, and ease the load on long-distance transmission lines
