Smart Distribution Automation System

The increased utilization of renewable energy sources (RES) and interconnected feeders require improvements in electric power distribution protection systems (DPS). The behavior of RES such as wind turbines and PV generators under fault and voltage transient events should be properly analyzed for the reconsideration of DPS design. In this paper, a distribution system employing wind turbines, PV generators, and interconnected feeders is analyzed using DIgSILENT software. A Smart Distribution Automation System (SDAS) with integrated DPS is proposed to achieve fault identification, isolation and restoration tasks.
