On the Reliability Improvement of Distribution Systems Using PV Grid-Connected Systems

The purpose of this paper is to examine issues related to the distribution system reliability improvement using photovoltaic (PV) grid-connected systems. The output characteristics of a PV system are experimentally measured. The measured data are used to investigate the efiects of PV system installation to improve the distribution system’s reliability. The system constraints such as, recovered real power, and loading reduction of the tie line/switch after the installation of PV grid-connected systems are concentrated. Simulation results show that with the action of a tie switch, system losses and loading level of the tie switch can be reduced with proper installation location.
