N2 - With the rapid development of power system and the integration of renewable energy sources, the uncertainties of power system become more complex, which introduce a more challenging for the assessment of voltage stability. This paper presents an analytical solution of static voltage stability assessment based on the PQ plane analysis method with elaborately selected voltage stability indices, and the load uncertainty is taken into account during analysis as well. Case studies are conducted based on the single-load-infinite-bus system, and the impacts of system key parameters and uncertainties of load on the voltage stability are studied respectively. Simulation results demonstrate that the proposed indices are effective in assessing the voltage stability closely pertinent to a load with low computational burden.
