Urban multi-energy distribution network(UMEDN)belongs to the terminal of Energy Internet's planning and operation. The coordinated planning of UMEDN is vital to improve the reliability and economy of energy supply. From the perspective of energy distribution network

an electricity/natural gas/heat distribution network coupling model that integrates electrical reconfiguration is proposed. First

a mathematical model of energy hub(EH)is constructed. Then

considering the constraints of urban distribution network

gas distribution network

heat distribution network and EH

simulating the working condition of UMEDN by hourly time scale

aiming at the minimum total cost

a mixed integer quadratic programming model is established. The best type

time and location of energy source

pipelines and EH via the proposed model are obtained. The simulation results show that the collaborative planning and operation of UMEDN incorporating electrical reconfiguration and EH can significantly improve system reliability

and reduce the capacity of related equipment

decrease energy distribution loss and the overall costs of planning and operation.
