汪泽, 李春兰, 王长云, et al. Research of the Large Photovoltaic Power Station Access Influence on the Stability of Distribution Network[J]. 2016, (4): 50-54. DOI: 10.16056/j.1005-7676.2016.04.014.
In view of the stability of the grid connected photovoltaic system
the influence of photovoltaic power station on the static voltage stability of distribution network was analyzed by drawing the P-V curve. The effects of PV power station
the three phase short circuit fault and the output fluctuation of photovoltaic power station on the transient voltage stability of the system were analyzed. The simulation results showed that when PV power station and grid connected closer
the stability of the voltage static would be better. With a shorter fault clearing time
the influence of the photovoltaic power station on the transient stability of the system would be smaller. The main factor that affected the stability of the system was the active power output fluctuation.
