Reliability Assessment of Distribution Power Network

As renewable energy sources become more widely available, distributed generation (DG) is expected to grow in distribution networks. This research presents a methodology for analysing the reliability of such distribution networks, which can be used in early planning studies. The IEEE 33-bus radial distribution system's reliability is tested first without DG and subsequently with DG connected at various load sites. The reliability indices are calculated using an analytical method. The influence of DG location, number, and availability on reliability indices is examined. The effect of random load variation on system reliability is studied. Because different DG locations provide different reliability indices, the location with the lowest value is picked.
