| 摘要: |
| 提出了一种考虑配电网重构及小时级潮流变化的配电-气网(EGDN)联合规划模型。一方面，融入配电网重构来优化系统的运行状态，两网协同规划能发挥不同能源间的互补共济作用，提升系统的可靠性和运行效率；另一方面，所提模型考虑小时级配电网和配气网的潮流方程，以精细化描述系统的运行状态。为了求解该非线性非凸模型，适当松弛原问题，将其转换为可直接求解的混合整数二阶锥规划(MISOCP)问题。仿真结果表明所提规划模型显著提升了系统的可靠性，降低了相关设备的配置容量，减少了能量传输损耗，降低了总体规划与运行费用，证明了MISOCP模型与简单的混合整数线性规划模型相比，更能获得满足实际工程需求的规划方案。 |

| Abstract: |
| A joint planning model of EGDN(Electricity-Gas Distribution Network) considering the reconfiguration of electricity distribution network and hourly power flow variation is proposed. On the one hand, the reconfiguration of electricity distribution network is integrated to optimize the operation state of the system, and the collaborative planning between the two networks can play a complementary and mutual role among different energy sources and improve the system's reliability and operational efficiency. On the other hand, the operation state of the system is described in detail by considering the power flow equation of electricity distribution network and gas distribution network hourly. In order to solve this non-linear non-convex model, the original problem is appropriately relaxed and converted into a MISOCP(Mixed Integer Second-Order Cone Programming) problem which can be solved directly. Simulative results show that the proposed planning model significantly improves the reliability of the system, reduces the configuration capacity of related equipment, decreases the energy transmission loss, and reduces the overall planning and operating costs. It proves that MISOCP model is more able to obtain the planning scheme meeting the actual engineering requirements, compared with the simple mixed integer linear programming model. |
