Impact of Green Power Distributed Generation

This article discusses green power distributed generation (DG) sources (of 10 MW or less), which are connected to a utility system at the distribution level, and their impact on distribution system reliability. The article also summarizes the specific reliability and protection issues in interconnecting green power generators to utility systems to mitigate the aforementioned reliability issues. These issues are not adequately discussed in IEEE standard 1547, which addresses the interconnection of DG to utility systems.
