Reliability enhancement of radial distribution systems with DG penetration

The paper investigates the impact of penetration of Distributed Generation (DG) on the reliability of a radial distribution network. The authors evaluate the reliability of a radial network with and without DG connection at different load points. Reliability evaluation is performed using the analytical and Monte Carlo Simulation (MCS) techniques and enhancement of reliability is compared with both techniques for DG placement at different load points. Results demonstrate that DG penetration does improve the reliability of the network and the location of DG in the network has an impact on the extent of improvement. Results clearly indicate that different locations give different reliability improvements and the location with the best improvement might be chosen.
