Modeling of DC/DC Converter for DC Load Flow Calculation

With the development of power electronic techniques, more and more attention has been paid to DC power systems. This paper analyzes the load flow issues containing DC/DC converters in a DC power system. The load flow model of DC/DC converters, which considers the power losses and control strategy of the converter, has been presented and integrated into the traditional load flow algorithm by modifying the Jacobian matrix. Two typical DC/DC converter examples have been presented: the boost converter and full bridge converter.
