Abstract

A computer implemented method, a system and computer program for time-domain phasor simulation of a power grid in an EMT simulation software are provided. The method a) builds a grid impedance matrix from passive electrical elements; b) separates the grid impedance matrix into real and imaginary parts; c) computes an inverse matrix of the real and imaginary parts of the grid impedance matrix, the inverse of the real part being named conductance matrix and the inverse of the imaginary part being named susceptance matrix; d) computes nodal current injections from active elements or sources; e) separates the computed nodal current injections into real and imaginary parts; f) executes (extended) nodal analysis algorithm on the conductance matrix with the real and imaginary parts of the current injection and on the susceptance matrix with the real and imaginary parts of the current injection, obtaining four voltage vectors; and g) builds a complex nodal voltage vector using the four voltage vectors.
