Shahnia, Farhad, Ghosh, Arindam, Ledwich, Gerard, & Zare, Firuz (2012) An approach for current balancing in distribution networks with rooftop PVs. In Proceedings of the 2012 IEEE Power and Energy Society General Meeting,, IEEE, Manchester Grand Hyatt, San Diego, CA, pp. 1-6.
Current unbalance is a significant power quality problem in distribution networks. This problem increases further with the increased penetration of single-phase photovoltaic cells. In this paper, a new approach is developed for current unbalance reduction in medium voltage distribution networks. The method is based on utilization of three single-phase voltage source converters connected in delta configuration between the phases. Each converter is controlled to function as a varying capacitor. The combination of the load and the compensator will result in a balanced load with unity power factor. The efficacy of the proposed current unbalance reduction concept is verified through dynamic simulations in PSCAD/EMTDC.
