非合同交易电力市场网损和输电设备瞬时使用程度分摊

LOSS AND TEMPORARY USAGE ALLOCATION FOR NON-CONTRACT ELECTRICITY MARKET

该文根据交流潮流计算结果 ,将线路充电电容功率、区域静止无功补偿功率、线路潮流、负荷节点和发电机节点功率分别用电流表示 ,得出支路电流有向流图。利用比例共享原则得出非合同交易中负荷节点MVA功率、发电节点MVA功率在线路电流中的贡献。利用非线性函数贡献因子理论得出负荷节点MVA功率、发电节点MVA功率对线路损耗功率、瞬时使用程度的贡献因子。由此能增加电力市场的透明度。该文方法的一个显著特点是理论基础可靠 ,所得基金项目 :教育部留学回国人员基金资助项目 ( 199936 3)。分摊结果十分简捷 ,可适用于电流实部和虚部方向不相同的系统运行情况。另外 。

Based on the results of AC power flow solution,the charging power,regional compensation reactive power,branch power flow,load node power and generation node power are represented by related currents,respectively.The current flow diagram is obtained.By using the proportionality share principle and topological analysis methods,the approach for tracing MVA load power and MVA generation power is proposed for the non contract market.Based on the newly developed nonlinear function contribution theory,the loss and temporary usage allocation method is proposed.The results can improve the transparency of power market.The advantage of the method is reliable theoretically and simple.The method in this paper can deal with the operation status where the direction of real part current is different from the direction of imaginary part current.Loss and temporary usage will not be allocated to regional compensation power and charging power.Detailed results are presented.
