Abstract

AbstractA comprehensive evaluation method for energy effectiveness of AC/DC hybrid distribution network is proposed in this paper. This paper first analyzes the topology and main working mode of AC/DC hybrid distribution system with HFB-EER, then analyzes the new factors affecting the effectiveness of AC/DC hybrid distribution system, and deduces the quantitative models of various factors. Then, from four aspects of medium voltage AC distribution network, EER and distribution transformer, low voltage DC distribution network and low voltage AC distribution network, the energy effectiveness evaluation index system of AC/DC hybrid distribution network with HFB-EER is constructed. Finally, taking a distribution network as an example, the effectiveness evaluation is carried out, and the results show that the improved evaluation index system can effectively evaluate the energy effectiveness.KeywordsElectric energy routerEffectivenessHigh frequency AC bus
