摘要(Abstract)：

为促进区域间资源互补互济，提升新能源消纳水平，提出一种计及直流联络线功率调整和电-气-热耦合的输配协同优化调度模型。首先，建立直流联络线的功率调整模型，利用联络线的调整能力提升系统运行灵活性；然后，针对受端电网建立考虑电-气-热耦合的主动配电网模型，在此基础上进行送受端直流联络线和受端输配协调多能互补系统的协同优化。采用线性化的交流潮流近似计算配电网网损，对天然气管道气流Weymouth方程的非凸性进行增量线性化处理，从而将模型转换为混合整数线性规划问题。最后，通过算例验证了所提模型和方法的有效性。
To promote inter-regional resource complementarity and improve the level of new energy consumption,a collaborative optimal scheduling model for coupled transmission and distribution systems considering DC tie-line power adjustment and electricity-gas-heat coupling is proposed. Firstly,a power adjustment model of DC tie-line is established to make full use of the adjustment capacity of the tie-line to improve the operation flexibility of the system. Secondly,an active distribution network model considering the electricity-gas-heat coupling is established for the receiving-end grid. Moreover,the coordinated optimization of the HVDC tie-line and the multi-energy complementary system of receiving-end is carried out. The linearized AC power flow is used for approximate calculation of the distribution network loss,and nonconvexity the Weymouth equation of natural gas pipeline flow is incrementally linearized. In so doing,the model in this paper is transformed into a mixed-integer linear programming(MIP)problem. Finally,an example is given to verify the effectiveness of the proposed model and method.
