“…Those residences without nonlinear loads were assumed to draw linear loads of 6.9 kVA at a 0.85 lagging power factor and were modeled as an appropriate parallel R-L combination [4]. Those residences with a nonlinear load were assumed to draw a linear load of 1 kVA at a 0.85 lagging power factor, which was also modeled as an appropriate parallel R-L combination, plus a 5.9 kVA nonlinear load.…”

Electric utilities have expressed concern over increased nonlinear loading of residential power distribution systems. The number and variety of power electronic products found in the typical home continues to grow rapidly, imposing a burden on local power companies to supply reliable, distortionfree service. In order to adequately prepare for the future, utilities must be able to predict the harmonic impact of new power electronic equipment and evaluate the ability of existing power systems to accommodate these nonlinear loads. This paper describes a modeling methodology that uses SPICE simulation software to predict the voltage distortion caused by nonlinear residential loads. Results of applying the methodology to a specific distribution system containing either of two different types of harmonic-rich loads, i.e., variable speed air conditioners or electric vehicle battery chargers, are presented as well.

A voltage source converter (VSC) is one of the most widely used power converters in a power system. In this paper, a timedomain-based accelerated steady-state method is proposed to solve for a closed-loop pulse-width modulated (PWM) VSC with dq-frame controllers, which is able to account for the harmonic interactions between the converter and the rest of the power network, between the AC and DC sides of a VSC, and between the converter and its controllers. The proposed time-domain method is based on the modified time-domain shooting method, where the Jacobian matrix is updated by the quasi-Newtons method. This will drastically increase the computation efficiency as it avoids re-evaluating and inverting the Jacobian matrix, whose size is usually very large for a PWM-VSC due to high number of times of switching. All the results are shown to be consistent with those obtained by a PSCAD/EMTDC model, which has been validated with the experiment in a previous publication.
