In this paper it is proposed a methodology for simulating the behavior of electrical distribution networks, with the presence of intermittent sources of energy, based on a computational environment integrating power system static and dynamic simulation. The methodology represents an improvement over the simple implementation of power flow cases for different points of time series representing the evolution of the daily load and intermittent generation, as it takes into account the chronological timing of the actions of control and protection devices. On the other hand, the computational requirements are similar to the execution of a sequence of power flow cases.
