When the photovoltaic power station is connected to the utility grid, the adverse impact was made on many aspects due to the inherent characteristics and the change of grid structure and power flow, such as power quality, planning operation and relay protection. For better use of solar energy and less effect on power energy quality of the system, making power quality testing and evaluation are needed in the design period before the photovoltaic substation connected into power system. In this paper, the power quality requirements of a practical distributed PV power station are summarized. The numerical model of grid-connected photovoltaic power station is built based on the Matlab/Simulink platform, and the power quality testing and evaluation of the photovoltaic substation connecting into power system are made. The results show that the power quality demands of the connecting points of the photovoltaic substation are satisfied, and the photovoltaic power station is allowed to connect into the power system.
