中文摘要：

针对当前集中交易为主同时存在大用户直供试点的市场模式，提出了一种点对点阻塞电价计算方法。给出了该算法的基本思想及详细描述．根据集中交易中无约束经济调度和考虑单个阻塞线路传输容量经济调度购电成本的差值计算阻塞线路传输单位能量的阻塞费用．进而基于功率传输分配系数矩阵计算点对点阻塞电价．根据需要可以在协议双方之间分摊。该算法中．加重阻塞的协议要支付阻塞费用．而减轻阻塞的协议应得到阻塞补偿．且阻塞费用（阻塞补偿）的大小取决于协议对阻塞线路潮流影响的程度。对PJM电力市场中的5节点算例进行了试算．并与金融输电权进行了对比，结果表明：点对点阻塞电价计算方法能够提供有效管理阻塞的经济信号．且简便易操作。

英文摘要：

To the current trial power market with primary centralized-agreements and a few bilateral -agreements,a calculation app＂oach for node-to-node congestion price is introduced. Its basic concept and detailed formulation are given. The congestion cost of each congested line for unit energy transmission is calculated according to the difference of the total energy cost between the economic dispatch with the corresponding single line capacity constraint and without any line capacity constraint. The node- to- node congestion prices are then computed based on the power transmission distribution factors. If necessary,the congestion price can be allocated to both parties of an agreement. The agreements aggravating congestion are charged while the agreements alleviating congestion are compensated,and the amount（congestion charge or compensation）depends on the influence on the congested power flows. A five-node example from the PJM power market is tested and compared with the financial transmission rights mode. Results indicate that this approach is easy to operate,supplying the economic signals for effective congestion management.
