Probabilistic load flow (PLF) is a powerful and widely used tool to address the random nature of renewable energy resources for planning operation power systems. In this study, new approach using combination multiple integral method (MIM) cumulant (CM) proposed PLF studies. The problem with high dimensionality decomposed into bi-level solved by MIM CM reduce computational burden significantly while achieving satisfactory accuracy. applied IEEE 118-bus system compared point estimate method. Simulation results show that achieves great efficiency
