In this paper, the harmonic penetration method is developed as a component-based application. The direct nodal voltage harmonic solution is developed as an independent software component and then integrated with existing three-phase power-flow software components. The harmonic solution reuses many facilities available in the fundamental frequency power-flow object components. The nonlinear devices such as six pulse converters are modeled as entity objects and inherited from the basic object-oriented power-system device model at fundamental frequency. Also, the linear solver also is reused form the power-flow component library. The application of object components shows that the development of complicated algorithms becomes easy due to the high code reusability.
