Tác giả hoặc Nhóm tác giả: Tran The Hoang, Quoc Bao Duong, Quoc Tuan Tran, Yvon Besanger, Tung Lam Nguyen
Nơi đăng: 2020 IEEE Power & Energy Society General Meeting (PESGM); Số: 1;Từ->đến trang: 1-6;Năm: 2020
Lĩnh vực: Kỹ thuật; Loại: Báo cáo; Thể loại: Quốc tế
TÓM TẮT
With the rapid advancement of power electronic technologies and the reduction of photovoltaic cell price, the share of solar energy in the total power production has been booming recently. On the one hand, the increase in the amount of power delivered by solar energy can be beneficial in many economic and environmental aspects. On the other hand, this can cause various technical challenges to network operators. One of these issues is related to classifying faults located in distribution networks with high penetration of photovoltaic systems. Although many studies have paid significant attention to developing new algorithms applicable for a more active today distribution networks, there is still space for other improvements. Hence, after reviewing state-of-the-art researches, this paper was intended to develop a fault classification that is based on artificial neural networks. In particular, a technique so-called Multiplayer Perceptron Classifier was selected for the proposed algorithm. First, the authors generated a data set for the study by modeling and simulating a real distribution network with practical parameters provided by a local utility in the environment software PowerFactory/DigSILENT. Multiple fault scenarios were simulated. Second, a part of the generated data collection was used for network learning. Finally, the performance of the proposed methodology was demonstrated via testing on the remaining number of generated data.
