摘要

城市多能源配网(UMEDN)处于能源互联网末端，实现UMEDN的协同规划与运行对提升多能量供给的可靠性与经济性至关重要。从能源配送网络的角度出发，提出了融合配电网重构的配电/气/热网扩展规划模型。首先，构建了能源集线器的数学模型；然后，考虑城市配电网、配气网、配热网以及能源集线器的相关约束，通过小时级别时间尺度模拟UMEDN的运行工况，以总成本最小为目标，建立了混合整数二次规划模型。采用所提模型可得到能量源、配送管道及能源集线器的最优建设类型、投运时间以及建设位置。仿真结果表明考虑配电网重构以及能源集线器的UMEDN协同规划能显著提升系统可靠性，降低相关设备的配置容量，减少能量传输损耗，从而显著降低总体规划与运行费用。

Abstract

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.
