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.
