The Impacts of PV-Wind-Diesel-Electric Storage Hybrid System on the Reliability of a Power System

The integration of renewable energy resources into the conventional distribution system has changed the single power source to bidirectional and multiple power sources. This will increase the reliability of the system and as well as reducing the power outage that is associated with the radial distribution network. This paper presents an analytical method to investigate the impacts of using photovoltaic (PV), wind turbine generator (WTG), electric storage system (ESS) and diesel generator on the reliability of the distribution power system. The proposed technique is implemented on the feeder 1 of the Roy Billinton Test System (RBTS) distribution network to establish the fact that renewable energy resources can be utilized to improve the reliability of a power system. The results obtained from the study show that the application of DG technologies has achieved better results.
