Abstract: The Distributed Generators (DGs) offer great opportunity to modernize the electrical infrastructure and apply the concept of the smart grid. One of the many virtues of the DGs is the expected improvement in the reliability of the power distribution systems. Specifically, the DGs could be used during major outages and blackouts to provide service to customers in the healthy parts of the distribution grid. In addition, it helps to alleviate the congestion of the electrical network during peak hours, which contributes to improving the reliability indices in all. In this work, we model the impacts of the DGs on the reliability and compare the results with those obtained when building new distribution substation at the feeder. Parts of the simulation will include a partial economic comparison on the savings from each option.

Keywords: Distributed generators, power system reliability, smart grid, microgrid
