Abstract:

This paper investigates the impact of photovoltaic generation system (pvgs) on the distribution system. The installations of various types of distributed generators (dgs) on the distribution system have significantly changed the operating, planning and maintaining strategies of the utility. In this paper, one practical Taiwan Power Company (taipower) distribution system with a large-scale of pvgs is selected for study. Many power quality issues like steady state voltage variation, reverse power, voltage unbalance, short-circuit current and harmonic are analyzed by considering many different operation scenarios of the distribution system and pvgs. The simulation results are compared with the related standards and it is found that the pvgs impact on the concerned power quality and reliability issues are all within the limits. It is concluded that the simulation results of the paper are very helpful to the electric utilities and pv producers for providing better power quality as well as increasing photovoltaic (pv) penetration in distribution grids.
