Abstract

To address the uncertainty of the distributed power generation, the information gap decision theory was deployed for modeling. First, the optimization model in planning the AC/DC hybrid distribution networks based on the soft open points was proposed by using the information gap decision theory, and selected the comprehensive cost and voltage fluctuation as the objective functions. Secondly, the fuzzy normalization and weighting processes were conducted on the aforementioned two objective functions. Finally, the proposed optimization model was tested based on the improved IEEE 33-node distribution system. The results show that the proposed model in planning the AC/DC hybrid distribution networks with soft open points can effectively improve the voltage quality, the economy and reliability of the AC/DC hybrid distribution networks.
