摘　　要：对跨区域互联电力市场的输电阻塞问题进行了分析,并提出了一种基于需求侧响应的阻塞管理方法,通过整合需求弹性、温控型负荷和可中断负荷等多种需求侧资源,和设置补偿价格、阻塞价格等价格信号,进行灵活的负荷计划调整,进而缓解和消除阻塞。根据用户的需求弹性系数建立了分时电价响应模型,并基于温控负荷的热力学特性建立了温控负荷和可中断负荷的联合响应模型。通过节点电价和最优潮流计算确定阻塞价格和补偿价格。并在考虑输电损耗和和用电时差的基础上,对跨区域互联系统阻塞问题进行了分析。分别设置了3个场景,对互联电力市场阻塞程度、区域电价、阻塞剩余等进行了详细的分析,验证了所提模型和阻塞管理机制的有效性。The transmission congestion problem of cross-region interconnected electricity market is studied, and a congestion management mechanism based on demand response is proposed. By integrating demand side resources such as demand elasticity, temperature- controlled loads and interruptible loads, and by setting reasonable price signals such as congestion price and compensation price, the mechanism can lead to flexible adjustment of load demands so that the congestion can be effectively relieved. The time-of-use response model is established according to user demand, as well as the integral optimization model of interruptible load and residential thermo- statically-controlled load. Congestion price and compensation price is determined by solving the multi-period optimal power flow equa- tions. Besides, the effect of transmission loss and time difference on degree of congestion of cross-region interconnected power system are also involved in the analysis. Three scenarios are set up to analyze the congestion condition, regional electricity price and congestion surplus, and the effectiveness of the proposed models and mechanism is verified.
