摘　　要：对某独立的地区电网中接入光伏电站的最大安装容量进行计算,并分析了在稳态情况下对电压和网损的影响以及光伏电站出力突变对系统暂态稳定的冲击影响。分析发现影响光伏电站容量的主要因素是节点电压的安全和稳定约束。The large-scaled photovoltaic power station will have an impact on the operation of electric grid, and the capac- ity calculation and analysis of the PV station to meet the requirements of security and stability of electric grid are the im- portant parts for planning and operating of PV station. The largest PV station＇s capacity in an independent area network I was calculated; the impacts on voltages and power losses under steady-state condition were analyzed; and also, the im- pacts on transient stability caused by variation of PV power were analyzed in the paper. The analyses reveal that the main factors affecting the capacity of PV power station am the security and stability of the bus voltage.
