Simulation studies on AC electric networks may comprehend periods of quasi-stationary operation and rapid transients. The adoption of a phasor-based approach results in high simulation efficiency; but is limited to the first of the two situations above; while for the second; time domain models are required. For system studies where both situations have to be simulated; a modelling paradigm is thus required that can join the two approaches in all the described components; and by which the simulator of an entire network can be endowed with the capability of moving back and forth from a phasor to a time domain system description automatically; taking care of the proper re-initialisations when necessary. In this paper we propose a possible solution; and apply our ideas by presenting the first nucleus of a Modelica library designed along them. We also show some simulation examples to support the validity and practical convenience of the proposal.

Keywords: AC networks; phasor models; time domain models; efficient simulation.
