Integrating Dispersed Storage and Generation(DSG) with an Automated Distribution System

Dispersed storage and generation (DSG) devices connected to an electric distribution system can cause operational problems-reenergization of distribution feeders under repair by utility personnel production of harmonics by DSG power inverters, and voltage regulation because of fluctuating DSG generation¿on an electric utility system. Many of these problems can be overcome by carefully applied automated control schemes. This paper discusses both emergency-and normal-state operations for distribution systems with DSG devices and presents concepts for improving these operations by applying automated control schemes.
