Abstract

See full text

An equivalent-conductance-compensated globally-linear symmetric method for obtaining power flows in a DC power network, including: establishing an equivalent-conductance-compensated globally-linear function that relates all bus translation voltages to a bus injection power according to given bus load parameters and given bus source parameters of the DC power network; establishing an equivalent-conductance-compensated globally-linear symmetric matrix-equation model for power flows in the DC power network according to the equivalent-conductance-compensated globally-linear function and a given slack bus serial number; establishing an equivalent-conductance-compensated globally-linear symmetric matrix relation between non-slack bus injection powers and all the bus translation voltages by using M-P inversion of matrices according to the equivalent-conductance-compensated globally-linear symmetric matrix-equation model; and calculating each bus per-unit voltage and each branch-transferred power in the DC power network according to the equivalent-conductance-compensated globally-linear symmetric matrix relation.
