A systematic approach to the construction of stochastic models of electric power systems for small disturbance stability analysis is presented. In this study, the cumulative effects of small-magnitude random fluctuations of electrical loads are considered as sources of eventual loss of stability, and a security measure is derived to determine the small-disturbance stability limits of the stochastic system. The electric power system models were tested on a 30-bus power system and compared according to the relative effects of load fluctuations on the proposed security measure
