Reliability Assessment of Power System with Renewable Source using ETAP

The reliability assessment of future distribution network is an important subject due to the increasing demand for reliable service with the need for a lower frequency and also lower duration interruption. The connection of future distribution networks may not be simple radial circuits and analysing the reliability of such a network is usually complicated and time consuming. In this project, the reliability in the distribution system by using Photovoltaic (PV) system as a Distributed Generation (DG) is described. The power flow analysis is also used to determine the optimum location and size for DG by using PSAT tool in MATLAB software. The IEEE 14-bus system is used to illustrate the analysis and calculate reliability indices by using ETAP software. Based on this study, the installation of DG can improve the voltage profile of buses and reduce power losses.
