Distributed generation as voltage support for single wire earth return systems [PDF]
IEEE Power Engineering Society General Meeting, 2004., 2004 Key issues for distributed generation (DG) inclusion in a distribution system include operation, control, protection, harmonics, and transients. This paper analyzes two of the main issues: operation and control for DG installation. Inclusion of DG in distribution networks has the potential to adversely affect the control of voltage.
