| 摘 要： | 节点边际电价在电力交易和处理输电阻塞中具有重要作用。文中建立了计算节点边际电价的线性规划模型，分析了利用传统线性规划方法求解节点电价存在的困难，提出了基于原–对偶内点法的节点边际电价计算方法。对典型的6节点电力系统进行了计算验证，结果表明，所提出的方法计算结果符合理论要求，计算速度快，收敛性好。

| Abstract: | Locational marginal price (LMP) plays an important role in electric power transaction and treatment of power transmission congestion. A linear programming model for calculation of LMP is established; the difficulties existing in the solution of LMP by traditional linear programming are analyzed; and a calculation approach for LMP based on primal-dual interior point method is proposed. The calculation results of typical 6-bus power system show that the proposed method can find satisfied result, the calculation speed is fast, and the convergence is good. |
