PROJECT TITLE :

A Generalized Approach to the Load Flow Analysis of AC-DC Hybrid Distribution Systems - 2017

ABSTRACT:

This paper proposes a unified load flow (LF) model for AC-DC hybrid distribution systems (DSs). The proposed model will be applied in hybrid DSs with mixed configurations for AC/DC buses and AC/DC lines. A brand new classification of DS buses is additionally introduced for LF analysis. A set of generic LF equations has been derived based mostly on comprehensive analysis of the possible AC-DC hybrid system configurations. 3 binary matrices, which are used as a means that of describing the configuration of the AC and DC buses and contours, have been employed in the construction of the unified power equations. These matrices enable one configuration at a time to be activated in the facility equations. The proposed LF model is generic and will be used for each grid-connected and isolated hybrid DSs. The new model has been tested using many case studies of hybrid DSs that embody completely different operational modes for the AC and DC distributed generators. As a suggests that of evaluating the effectiveness and accuracy of the proposed model, the LF solution was compared to the answer made by PSCAD/EMTDC. A comparison of the results reveals the efficacy of the proposed model.
