Abstract:	摘要： The Kyoto protocol recommended that industrialized countries limit their green gas emissions in 2012 to 5.2% below 1990 levels. Photovoltaic (PV) arrays provide clear and sustainable renewable energy to electric power systems. Solar PV arrays can be installed in distribution systems of rural and urban areas, as opposed to wind-turbine generators, which cause noise in surrounding environments. However, a large PV array (several MW) may incur several operation problems, for example, low power quality and reverse power. This work presents a novel method to reconfigure the distribution feeders in order to prevent the injection of reverse power into a substation connected to the transmission level. Moreover, a two-stage algorithm is developed, in which the uncertain bus loads and PV powers are clustered by fuzzy-c-means to gain representative scenarios; optimal reconfiguration is then achieved by a novel mean-variance-based particle swarm optimization. The system loss is minimized while the operational constraints, including reverse power and voltage variation, are satisfied due to the optimal feeder reconfiguration. Simulation results obtained from a 70-bus distribution system with 4 large PV arrays validate the proposed method. 出版者： Cairo, Egypt: Hindawi Publishing Corporation 出版日期： 2014-01-01 出處： International Journal of Photoenergy, 2014-01, Vol.2014 (2014), p.1-10 資源來源： Directory of Open Access Journals (DOAJ) 版權： Copyright © 2014 Ying-Yi Hong et al. 版權： COPYRIGHT 2014 John Wiley & Sons, Inc. 版權： COPYRIGHT 2014 Hindawi Limited 版權： Copyright © 2014 Ying-Yi Hong et al.
