Abstract: The distribution system is prone to failures and disturbances due to weather related issues and human errors. The distributed generation is expected to play a key role in the power system. The reliability of the power supply can be improved in the presence of distributed generation (DG). In this paper, general assessment of the impact of distributed generation (DG) on the distribution system reliability is presented. The reliability improvement is measured by reliability indices. A typical case study is presented where distribution system reliability indices are calculated for an existing system without DG and compared with insertion of DG in the system.
