摘要
就全国大学生数学建模竞赛2004B电力市场的输电阻塞管理问题,利用多元线性回归分析,给出了各线路上有功潮流关于各发电机组出力的近似表达式;通过引入阻塞费用补偿价格因子,给出了阻塞费用计算公式;按照安全性、经济性目标,建立了输电阻塞管理问题的规划数学模型;对利用MATLAB优化工具箱求解的结果进行了分析与检验,验证了所建模型及所提算清的正确性和有效性.
In terms of the management of transmission congestion in power market in CUMCM2004, the approximation formula of active power flow in all lines concerning motor generators' injection power is presented by means of multivariate linear regression analysis. Furthermore, a formula is posed to reckon the cost of transmission congestion through the introduction of the congestion cost compensation price-factor. Based on the principle of safety and economy, the programming models to eliminate transmission congestion are constructed. The results from MATLAB optimization toolbox as well as the rationality and validity of these models are analyzed and tested.
