输电阻塞的费用计算与分配

Adjustment and Calculation of Transmission Electrity Congestion Cost in Electric Power Markets

为了解决输电阻塞管理的现实问题,给出了一个以购电费用最小为目标的阻塞费用计算和分摊模型。首先利用Lagrange乘子法求出阻塞费用;其次又提出了基于Aumann-Shapley值的阻塞费用分摊法,应用Gauss-Legendre积分公式求出每条阻塞线路上的阻塞费用;最后根据各发电机组对阻塞线路的贡献,将阻塞费用再分摊到各发电机组。

With the reform and development of electricity market in our country,the transmit electricity congestion seems to be important. To solve the practical problems ,this paper gives an congestion cost calculation and share model which is aimed for the minimum fee purchasing costs. First, using Lagrange multiplies acquire congestion cost. Second, providing congestion cost sharing based on Aumann-shapley value, applying Gauss-legendre integrate formula to obtain the congestion cost of every congestion lines. Lastly, according to every generator contributes to congestion lines, the congestion cost shares to every generator.
