Screening method for DG interconnection to distribution system

Penetration level of distributed generation (DG) on the grid is increasing worldwide. For the connection of new DG to the distribution network, various factors are considered including technical requirements that ensure the DG does not adversely affect the operation and safety of the network. Distribution system operators (DSO) have to perform impact studies of DG but these studies need cumbersome modeling and simulating of the target distribution network whenever DG is connected and the long time required for technical review. Therefore, utility engineers need the screening methods that can straightforwardly indentify cases with no impact on distribution system or those applications requiring detail studies. This paper presents the screening process and evaluation methods with simple rule on bank level and feeder level, respectively.
