This paper summarizes basic principle and output characteristic of grid-connected photovoltaic generation system. Gansu Jinchang power grid was selected as an example for analyzing affect on the power grid by photovoltaic generation in aspects of load characteristic,voltage,power grid protection,power grid planning,dispatching operation and dispatching automation. Combining self safe and stable operation of Jinchang power grid,relevant technical requirements for grid-con-nected photovoltaic generation system were proposed from the point of technical reliability which was of importance to en-sure safe and stable operation of Jinchang power grid.
