Routing Planning Strategy of Energy Router Based Power Distribution Systems Considering Transmission Line Fault

Energy internet is a new generation of integrated energy system with electric power as its hub and platform. Energy router is the basic equipment of future energy internet, so it is very important to study routing planning strategies. Existing studies only propose planning schemes with the objective of minimizing power losses, but a single planning objective cannot meet the needs of the continuously developing distribution network. Transmission lines in distribution network may occur fault due to internal and external factors of power system. In order to improve the reliability of power supply in distribution network, this paper proposes a multipath routing planning strategy which considers the conversion losses of energy router, transmission losses of transmission line and transmission line fault rate. The routing planning strategy proposed in this paper adopts multiple paths to transmit power, which can effectively reduce the power transmission losses between energy routers, prevent power transmission congestion in transmission lines, and adaptively allocate the transmission power of different paths, thus improving the reliability of power supply in distribution network. The effectiveness of the proposed routing planning strategy is verified by simulation, and compared with conventional multipath routing planning strategy, the superiority of the proposed strategy is verified.
