Experimental Multi-objective Evaluation of Radial and Loop Distribution Network Configuration Using Distribution Network Equipment

摘要

In this paper, the authors propose an experimental multi-objective evaluation method based on use of distribution network equipment to evaluate distribution network configuration candidates with distributed generators such as photovoltaic generation system and wind power generation system by hourly changing states of sectionalizing switches satisfied with constraints of voltage and line current limit. In the proposed experimental multi-objective evaluation method, the optimal network configuration is determined by using multi-objective evaluation based on total distribution loss rate, maximum voltage total harmonic distortion, and maximum voltage imbalance rate in order to reduce distribution loss and keep power quality. The proposed method is applied to radial and loop distribution network configuration by using an experiment of scaled-down three-phase distribution network with one bank distribution transformer, 5 distribution lines, 5 sectionalizing switches, 12 single-phase loads and 5 DGs.
