Grid integration of solar photovoltaic (PV) systems has been escalating in recent years, with two main motivations: reducing greenhouse gas emission and minimizing energy cost. However, the intermittent nature of solar PV generated power can significantly affect the grid voltage stability. Therefore, intermittent solar PV power generation and uncertainties associated with load demand are required to be accounted to gain a holistic understanding on power grid voltage stability with high penetration of PV energy sources. This paper presents a framework for power grid voltage stability analysis considering uncertainties associated with PV power generation and load demand using Monte Carlo simulation. Commonly used voltage stability indicators such as critical eigen value, line loss, reactive power have been considered in the proposed framework. The proposed methodology has been verified by analysing voltage stability of IEEE 14 bus test system, with high penetration of PV energy sources and considering uncertainties associated with load demand. The results provide a clear insight to voltage stability of power grid with different penetration level of PV energy sources into the power grid.
