Study of reliability of grid connected photovoltaic power based on Monte Carlo method

Research the influence of the reliability after the photovoltaic power station connected to distribution network. First, The basic method and analysis index of the reliability analysis to distribution network with photovoltaic power are introduced. Then, the example model has been established, that PV power is connected to the node of downstream end of the trunk line in distribution system. The reliability of the distribution network with photovoltaic power are analyzed by using Monte Carlo simulation. Finally, the line in distribution system with PV power is sampled by Monte Carlo simulation, and the index of load point and system are got a statistical then. The results is shown that reliability level of the distribution system´s supply and operation can be improved by connecting photovoltaic power to system reasonable, and operation of the grid can be more reliable and stable.
