This paper presents the application of aprobabilistic multi-stability assessment of a modified two-areasystem under the presence of low and high uncertainty sources.The stability of the network is assessed under four stabilityregimes: frequency, small-signal rotor angle, large-signal rotorangle, and long-term voltage. The probabilistic assessment iscarried out using Monte Carlo simulation. Two casesconsidering low and high uncertainty are investigated. Theobtained results are presented in the form of parallel coordinateplots so that the interaction between multiple stability regimescan be more easily understood. It is observed that the poorresponse of small-signal rotor angle stability generallycorresponds to poor response of other stability types in lowuncertainty case. However, once the level of uncertaintyincreases and more sources of uncertainty exist, thisrelationship is significantly changed
