1. A method for power system model conversion and quality verification, the method comprising:
obtaining a phasor-domain model of a power system;
obtaining a raw file that represents a representable subset of parameters of the phasor-domain model as parameters of a bus-branch model;
modifying values of the parameters of the bus-branch model in the raw file as needed for the raw file as modified to represent the representable subset of parameters of the phasor-domain model with at least a minimum level of accuracy;
generating, from the phasor-domain model, a supplementary file that represents a non-representable subset of parameters of the phasor-domain model which is not representable by the raw file;
obtaining a time-domain specific parameter file that represents parameters specific for modeling the power system in a time-domain;
converting the phasor-domain model of the power system to a time-domain model of the power system, based on the raw file as modified, the supplementary file, and the time-domain specific parameter file; and
performing fault simulation-based quality verification of the time-domain model by:
comparing results of fault simulation in the power system as modeled with the phasor-domain model and results of fault simulation in the power system as modeled with the time-domain model; and
based on said comparing, modifying the time-domain model as needed to reduce discrepancy between the results of fault simulation in the power system as modeled with the phasor-domain model and results of fault simulation in the power system as modeled with the time-domain model.
