The access of large-scale wind power has a serious impact on the voltage stability of AC/DC power systems. In this paper, probabilistic events combined with risk assessment are applied to the analysis of voltage stability and voltage stability risk indicators are proposed. Based on the improved Monte Carlo method, the Latin hypercube sampling establishes a risk assessment process for AC/DC voltage stability. The weak areas of the system are accurately identified, and different wind power access scenarios and VSC control mode and control parameters are studied. The feasibility of the proposed evaluation method was verified by an improved 10-node and 39-node system.
