Abstract

The grid connected PV systems represent the future growing market segment today; their influence on the utility is emphasized in this paper. A power balanced model of a grid-connected PV system is developed on PSASP, this model focuses on the injection power of the PV system, the dynamic relationship between the injection power and the solar radiation is mathematically described, the dynamic power flow of the PV system caused by the typical days in different weather mode is simulated, the fluctuations of the utility voltage caused by the change of the injection power are analyzed, load characteristics influenced by the PV Systems are explored in detail.
