چکیده
The research work done in this paper is directed into two main routes. The first one is evaluating the impact of different conventional and renewable types of generation techniques on distribution systems’ reliability. The second route is developing an appropriate algorithm to model the operation schedules of distributed generators to obtain realistic and applicable reliability analysis for distribution systems integrated with distributed generators. Case studies are offered and the results obtained are presented and discussed.
