| Abstract: | This paper firstly introduces the PV generation related principle,the operation mode of PV systems,and summarizes the current research about the impact of PV connection to the grid.Secondly,the model of PV system is established based on software PSASP,in which the characteristics of PV cell are simplified.In the light of Benchmark＇s model,typical middle voltage distribution networks and micro-grid of low voltage are simulated which is in different access forms under different weather conditions.The study also takes the capacity of PV generation systems into consideration,along with the impact to voltage quality of steady-state operation,and the measures are put forward to improve the voltage quality at last. |
